The rebel barons of England formally repudiate their feudal allegiance to King John — a step known in medieval law as diffidatio — and begin the brief, decisive civil conflict that historians now call the First Barons' War. Six weeks later, on 15 June 1215, John will be obliged to seal the Great Charter — Magna Carta — at Runnymede on the Thames, the document that for the first time binds an English king under the law and that, half a millennium later, gives the American Founders the language of due process and trial by jury.

At a kurultai of his supporters at Kaiping in Inner Mongolia, the 45-year-old Kublai — grandson of Genghis Khan — is proclaimed Great Khan of the Mongols. The election is contested by his younger brother Ariq Böke, and the resulting four-year civil war ultimately splinters the unified empire into the four khanates. Kublai goes on to complete the conquest of Song China and, in 1271, founds the Yuan dynasty in Beijing — the first non-Chinese dynasty to rule all of China. Marco Polo will spend seventeen years at his court and bring back to medieval Europe the first reliable accounts of the empire's scale, sophistication and paper money.

In Connecticut, Mary Dixon Kies receives a US patent for a technique of weaving straw with silk and thread — used in the manufacture of fashionable bonnets at a time when President Jefferson's embargo had cut off European imports and millinery had become an unexpectedly lucrative American industry. The patent is signed by President James Madison himself; First Lady Dolley Madison sends Kies a personal letter of congratulation. Kies is the first American woman known to receive a US patent in her own name; her original patent papers were destroyed in the great Patent Office fire of 1836, but the certificate and the date have been confirmed from contemporary records.

The 20-year-old apprentice surgeon John Keats sees his first poem in print — the sonnet "O Solitude! if I must with thee dwell" — published by Leigh Hunt in the radical London weekly The Examiner. Keats has only nine more years to live; in those years he will write "Ode to a Nightingale," "Ode on a Grecian Urn," "To Autumn" and the unfinished "Hyperion," and become one of the central figures of English Romantic poetry. He dies in Rome of tuberculosis in 1821 at twenty-five, asking that his epitaph read: "Here lies one whose name was writ in water."

On the same day Napoleon dies on Saint Helena, the first issue of The Manchester Guardian appears in the cotton-mill capital of the English north — a weekly newspaper founded by the textile merchant John Edward Taylor in the wake of the Peterloo Massacre to give a moderate, reform-minded voice to the new industrial middle classes. It will become a daily in 1855, drop "Manchester" from its name in 1959, and remain one of the world's most influential English-language papers — defining Britain's liberal tradition, breaking the Snowden / NSA story in 2013, and now read worldwide as simply The Guardian.

In the dense second-growth thickets of Spotsylvania County, Virginia, Union forces under Lieutenant General Ulysses S. Grant and Confederate forces under General Robert E. Lee meet in the first engagement of Grant's Overland Campaign — the start of an unbroken series of battles that will end eleven months later at Appomattox. The two-day fight is brutal: dry undergrowth catches fire and burns wounded soldiers alive between the lines. Casualties are roughly equal — about 18,000 Union, 11,000 Confederate — but where every previous Union commander has retreated after a draw with Lee, Grant orders his army to advance. His soldiers cheer when they realise which way they are marching.

In the small upstate town of Waterloo, New York, businesses close, flags fly at half-staff and townspeople carry flowers and flags to the graves of Civil War veterans in a coordinated village-wide observance — the first Memorial Day. Several other American towns claim the original observance, but Waterloo's case rests on the day being a planned, official, community-wide event repeated every year afterward, and on May 7, 1966, exactly a hundred years on, President Lyndon B. Johnson and Congress jointly recognised Waterloo as the official birthplace of the holiday. Memorial Day was moved to the last Monday in May by federal law in 1971.

In Milwaukee, four days after the Haymarket affair in Chicago and the international general strike of May 1, 1886 that gave the world International Workers' Day, about 1,500 workers march on the North Chicago Rolling Mill Steel Foundry in Bay View demanding the eight-hour day. Wisconsin Governor Jeremiah Rusk has already ordered the state militia in. On the orders of Major George Traeumer the militiamen open fire on the unarmed marchers; seven people, including a thirteen-year-old, are killed. The Bay View Massacre, together with Haymarket, becomes the founding tragedy of the American eight-hour-day movement and is commemorated at the site every May.

At the Huntington Avenue Grounds in Boston, the 37-year-old Denton True "Cy" Young of the Boston Americans — the team that becomes the Red Sox three years later — pitches a perfect game against the Philadelphia Athletics, retiring all 27 batters he faces and striking out eight. The Americans win 3–0 in 83 minutes. It is the first perfect game in the modern major-league era (1900 onwards) and only the third in major-league history. Young finishes his career with 511 wins — a record that, like Joe DiMaggio's 56-game hitting streak, no modern pitcher has come close to. The annual award given to the best pitcher in each Major League is named for him.

At the Old Bailey in London, the trial opens of brothers Alfred and Albert Stratton for the brutal robbery and double murder of an elderly couple, Thomas and Ann Farrow, who ran a small paint shop in Deptford, South London. Detective Inspector Charles Collins of Scotland Yard testifies that a single thumbprint left on the Farrows' empty cash box matches Alfred Stratton's. The Strattons are convicted and hanged. It is the first murder conviction in the world to rest on fingerprint evidence — the foundation stone of every detective drama since.

In her boutique on the Rue Cambon in Paris, the 38-year-old Gabrielle "Coco" Chanel launches her first perfume — Chanel No. 5 — in a deliberately austere rectangular bottle that breaks every convention of belle-époque perfumery. The Russian-born perfumer Ernest Beaux has presented her with ten samples; she chooses the fifth. The blend of about eighty ingredients with a heavy aldehyde top note is unlike anything else on the market. Marilyn Monroe's 1952 reply to a question about what she wore to bed — "five drops of Chanel No. 5" — fixes the scent in popular culture forever; a century later it remains one of the world's best-selling perfumes.

In the small Tennessee town of Dayton, the 24-year-old high-school biology teacher and football coach John T. Scopes is arrested under the state's newly passed Butler Act for teaching Charles Darwin's theory of evolution from a state-approved textbook. The arrest has been engineered by a coalition of local boosters and the American Civil Liberties Union as a deliberate test case. The "Monkey Trial" that opens in July, with William Jennings Bryan prosecuting and Clarence Darwin's old friend Clarence Darrow defending, is the first American trial broadcast live by radio and the most watched legal proceeding of the 1920s. Inherit the Wind, the 1955 play and 1960 film loosely based on it, has kept the case in the American imagination ever since.

The Hogarth Press, the small London publishing house she runs with her husband Leonard, brings out Virginia Woolf's fifth novel, To the Lighthouse — drawn from her childhood summers in St Ives, Cornwall, and a quiet, devastating portrait of her parents. Its three-part structure ("The Window," "Time Passes," "The Lighthouse") and stream-of-consciousness method become defining marks of literary modernism. The Modern Library has it on its list of the hundred best English-language novels of the twentieth century; the Time critic in 2005 called it one of the all-time hundred best novels. Woolf herself, characteristically, wrote: "I have had my vision."

Marshal Pietro Badoglio, at the head of the mechanised columns of Mussolini's Royal Italian Army, enters the Ethiopian capital Addis Ababa, completing the Italian conquest of one of only two African states never colonised by Europe. Emperor Haile Selassie has already left for exile in Britain, where his June 1936 speech to the League of Nations in Geneva — "It is us today; it will be you tomorrow" — becomes one of the most prophetic moral warnings of the inter-war era. The League's failure to enforce sanctions on Italy is widely held to be the moment international collective security collapsed; appeasement and the Second World War follow. Selassie returns to a liberated Addis Ababa on 5 May 1941, exactly five years to the day later.

On a forested mountainside near Bly, Oregon, the 26-year-old pregnant Mrs. Elsie Mitchell and five Sunday-school children find a strange paper balloon caught in the trees on a church picnic. As her husband, the Reverend Archie Mitchell, walks back toward their car, the device explodes. They are the only six people killed by enemy action in the continental United States during the entire Second World War. The balloon is one of about 9,300 Fu-Go incendiary balloons launched by the Japanese Army at the North American jet stream from late 1944; only about 300 are confirmed to have reached the continent, and the US government suppressed the story so successfully that the Japanese, hearing nothing, eventually halted the program.

In St James's Palace in London, ten Western European foreign ministers — Belgium, Denmark, France, Ireland, Italy, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom — sign the Statute of the Council of Europe. The Council, distinct from the European Union with which it is sometimes confused, is the continent's oldest political organisation; it now has 46 member states. Its great instrument is the European Convention on Human Rights, signed in Rome a year and a half later in November 1950, and the European Court of Human Rights it created. In 1964 the Council declared 5 May annually as Europe Day in commemoration of its founding (the European Union's separate Europe Day, 9 May, marks the 1950 Schuman Declaration).

The General Treaty (Deutschlandvertrag) signed in Bonn the previous year between the Federal Republic of Germany and the Western Allies — the United States, Britain and France — comes into effect, ending a decade of Allied military occupation and restoring full sovereignty to West Germany under Chancellor Konrad Adenauer. Four days later, on 9 May, West Germany joins NATO. The Federal Republic's reintegration into the West, together with the Wirtschaftswunder over which the economist Ludwig Erhard presides, is the political miracle of post-war Europe; reunification with the East follows on 3 October 1990.

At Churchill Downs in Louisville, the great chestnut three-year-old Secretariat — owned by Penny Chenery and trained by Lucien Laurin — wins the 99th Kentucky Derby in 1:59 2/5, the first horse ever to run the mile-and-a-quarter in under two minutes, and a record that more than half a century later has still never been broken. Secretariat goes on to take the Preakness and to win the Belmont Stakes by an unfathomable 31 lengths — generally considered the greatest single performance in racing history — completing the first US Triple Crown in 25 years. ESPN's 1999 Athletes of the Century list ranks him the 35th-greatest American athlete of the 20th century; the only non-human on the list.

On the sixth day of the Iranian Embassy siege at 16 Princes Gate in Knightsbridge, London — six gunmen of the Democratic Revolutionary Front for the Liberation of Arabistan have been holding 26 hostages — Special Air Service troopers in black assault suits and gas masks abseil down the back of the building and blow in the front windows on live television. In a 17-minute assault watched by an estimated audience of millions on BBC and ITV, five of the six terrorists are killed and one hostage dies; the rest are freed. Operation Nimrod is the most televised counter-terrorist operation in history and the moment that turned the SAS, until then largely unknown to the public, into a household name.

In the Maze Prison south of Belfast, the IRA prisoner Bobby Sands dies after 66 days without food, age 27. He had begun his fast on 1 March demanding political-prisoner status — denied to IRA inmates by Margaret Thatcher's government. While on hunger strike, on 9 April, he had been elected Member of Parliament for Fermanagh and South Tyrone in a by-election; about 30,000 mourners attend his funeral. Nine other republican prisoners die before the strike ends in October. Sands's death is one of the defining political moments of the Northern Ireland Troubles; the conflict will continue for another seventeen years until the Good Friday Agreement of 1998.

Sam Raimi's Spider-Man, with Tobey Maguire as Peter Parker and Kirsten Dunst as Mary Jane Watson, becomes the first motion picture in history to gross more than $100 million in its North American opening weekend — taking $114.8 million from Friday May 3 through Sunday May 5. The Sony / Columbia release also breaks the single-day record on its Saturday with $43.6 million. The film triggers the modern superhero-blockbuster era that, two decades later, dominates the global box office. Stan Lee, the creator of the Spider-Man character, makes a brief cameo as a New Yorker pulling a child out of falling debris.

Danish philosopher, theologian and cultural critic, born in Copenhagen, often called the father of existentialism. His pseudonymous masterworks — Either/Or (1843), Fear and Trembling (1843), The Concept of Anxiety (1844), The Sickness Unto Death (1849) — argue that authentic human life is a matter of personal, existential choice and a "leap of faith" rather than abstract philosophical reasoning. He died at 42 from a fall in the street, having spent the last years of his life in a public quarrel with the Danish state Lutheran church. The 20th-century existentialism of Heidegger, Sartre, Camus and Karl Jaspers, and the dialectical theology of Karl Barth, both flow directly out of his work.

Polish journalist and novelist who won the 1905 Nobel Prize in Literature "because of his outstanding merits as an epic writer." Best known internationally for Quo Vadis (1896), his novel of Christians and Romans in the time of Nero, made into the 1951 Hollywood epic with Robert Taylor and Peter Ustinov. His historical Trilogy — With Fire and Sword, The Deluge, Fire in the Steppe — about 17th-century Poland is read in Poland the way the Indian subcontinent reads the Mahabharata. He died in Switzerland during the First World War and his remains were repatriated to a free Poland in 1924.

American journalist, born Elizabeth Cochran near Pittsburgh, Pennsylvania. Two pieces of work made her the most famous woman reporter of her era, both for Joseph Pulitzer's New York World. In 1887, at 23, she got herself committed to the Blackwell's Island Lunatic Asylum in New York City and produced Ten Days in a Mad-House, an undercover exposé of the brutality there that triggered a grand-jury investigation and reform. Two years later, she beat the fictional record set in Jules Verne's Around the World in Eighty Days by sailing east from New York and reading every dispatch by telegraph; she completed the round trip in 72 days, 6 hours and 11 minutes. Verne, when she met him in Amiens en route, told her he didn't think it could be done.

English campaigner for women's suffrage, socialist, anti-fascist activist and friend of Ethiopia. Daughter of Emmeline Pankhurst and sister of Christabel; she split with both over politics, being more radically socialist and more sympathetic to working-class women than the Pankhurst mainstream. Imprisoned, force-fed, and active across half a century of British public life. From the 1930s she campaigned tirelessly against Mussolini's invasion of Ethiopia and was an early supporter of Emperor Haile Selassie; she eventually moved to Addis Ababa in 1956 and is buried there at the Holy Trinity Cathedral, a rare honour for a foreigner.

British general and the penultimate Viceroy and Governor-General of India, 1943–1947. As Commander-in-Chief in the Middle East at the start of the Second World War, he led the brilliant Operation Compass that destroyed an Italian army many times the size of his own in the Western Desert; later, as commander in India, he organised the eventual reconquest of Burma. As Viceroy he warned London repeatedly that India must be granted independence quickly and on Indian terms, and was eventually replaced by the more politically agile Mountbatten. A literary man unusual in his caste — his anthology Other Men's Flowers, a poetry collection compiled from memory in his soldier-poet's notebook, has remained continuously in print since 1944.

British prehistoric archaeologist, the first woman ever to hold a chair at either Oxford or Cambridge: in 1939 she was elected Disney Professor of Archaeology at Cambridge — at a time when women were still not yet full members of the university and could not vote in its governance. Her 1928–34 excavations at the Mount Carmel caves in British-Mandate Palestine produced the skeleton of a Neanderthal woman now known as Tabun I and revolutionised understanding of the relationship between modern humans and Neanderthals in the eastern Mediterranean. Her election as Cambridge professor — and the inability of the university to actually formally admit her until two years later — is one of the great early-20th-century landmarks in the academic emancipation of women.

American chef, cookbook author, food columnist and television presenter, born in Portland, Oregon. He hosted the first cooking show on American network television, NBC's I Love to Eat, in 1946; published the encyclopedic James Beard's American Cookery in 1972; and was unofficially crowned "Dean of American Cookery" by The New York Times. After his death in 1985, his Greenwich Village townhouse became the home of the James Beard Foundation, and the foundation's annual James Beard Awards — sometimes called "the Oscars of food" — remain American cooking's most prestigious honours, given to chefs, restaurants, cookbooks and food journalism alike.

Bengali revolutionary nationalist and freedom fighter, born at Dhalghat in Chittagong (now in Bangladesh), often called "Bengal's first woman martyr." After topping her intermediate exams in Dhaka and graduating in philosophy from the Bethune College in Calcutta, she returned to Chittagong as a school headmistress and joined the revolutionary group of Surya Sen. On 23 September 1932, dressed as a man, she led a small armed unit in a raid on the Pahartali European Club — which famously kept a sign reading "Dogs and Indians not allowed." Wounded in the action and unwilling to be taken alive, she swallowed a potassium-cyanide capsule. She was 21. Her courage made her an icon of the Indian independence movement and one of the most powerful examples of a woman's sacrifice for the freedom of India.

American actor, born in Cincinnati, Ohio into a four-generation theatrical family — his father, also Tyrone, was an Irish-born star of stage and silent film. The leading romantic male star at 20th Century Fox in the late 1930s and '40s. Defining roles include the dashing Don Diego in The Mark of Zorro (1940) opposite Basil Rathbone, the bullfighter Juan Gallardo in Blood and Sand (1941), the unsettling carnival drifter in the noir Nightmare Alley (1947) and the courtroom thriller Witness for the Prosecution (1957) opposite Marlene Dietrich. He served as a Marine pilot in the Pacific in the Second World War and died of a heart attack at 44 while filming Solomon and Sheba in Madrid.

American physicist, born in Mount Vernon, New York and raised in Toronto. With his brother-in-law Charles Townes he co-authored the seminal 1958 paper that proposed the laser; with the engineer Theodore Maiman, who built the first working laser two years later, he stands at the foundation of one of the most consequential technologies of the 20th century — from supermarket scanners and optical fibre to laser eye surgery and the LIGO gravitational-wave detectors. Long-time Stanford professor; shared the 1981 Nobel Prize in Physics with Nicolaas Bloembergen and Kai Siegbahn for laser spectroscopy.

American actress and comedian with a voice unmistakable to two generations of children: Ursula, the sea witch, in Disney's The Little Mermaid (1989) — a performance the Disney animators built much of the character's look around. Earlier she won an Emmy in 1957 for the variety series Caesar's Hour with Sid Caesar; later she received critical acclaim for her one-woman stage show as the writer Gertrude Stein. Voiced Granny in Tom and Jerry: The Movie (1992) and made guest appearances in everything from Designing Women to ER. Died at 95 in 2022.

American country singer-songwriter, born Virginia Wynette Pugh near Tremont, Mississippi. Her 1968 recording "Stand by Your Man," co-written with the producer Billy Sherrill, is among the best-selling singles in country-music history and one of its most-debated lyrics. Her marriage to fellow country giant George Jones from 1969 to 1975 produced both unforgettable duets ("We're Gonna Hold On," "Golden Ring") and one of the great mythic American break-ups. Twenty-number-one country singles, three Grammy Awards, and the title — Country Music Hall of Fame, 1998 — that goes with the canonical nickname.

English actor, comedian, writer and travel-documentary maker, born in Sheffield. A founding member of Monty Python's Flying Circus (1969–74), in which he co-wrote and performed many of British comedy's most-quoted sketches: the Spanish Inquisition, the Lumberjack Song, Dead Parrot. Later acclaimed for A Fish Called Wanda (1988), for which he won the BAFTA for Best Supporting Actor. From 1989 he became one of the BBC's defining travel presenters with Around the World in 80 Days, Pole to Pole, Full Circle, Sahara, Himalaya and many more. Knighted by Queen Elizabeth II in 2019. Both kindly and tirelessly inquisitive in everything he does — Pythons reliably named him "the nicest Python."

Welsh-born actor, one of the great character players of his generation. Two roles have made him beloved across the world: Gimli, son of Glóin, in Peter Jackson's The Lord of the Rings trilogy (2001–03) — for which he was put through hours of prosthetic makeup every day and developed a remarkable allergy to one of the foam latex bases; and Sallah, the irrepressible Egyptian friend of Indiana Jones in Raiders of the Lost Ark (1981) and Indiana Jones and the Last Crusade (1989). Also memorable as Pugachev in Sakharov (1984), Vasco Rodrigues in the original Shōgun (1980) and the voice of the wizard Cassim in Aladdin and the King of Thieves (1996).

British actor, born in Saint Helier, Jersey, in the Channel Islands. He played the eponymous lead in The Tudors (2007–10) on Showtime, and rose to global fame as Superman / Clark Kent in Zack Snyder's Man of Steel (2013), Batman v Superman: Dawn of Justice (2016) and Justice League (2017). Also a notable Sherlock Holmes opposite Millie Bobby Brown in Enola Holmes (2020) and a lethal Geralt of Rivia in three seasons of Netflix's The Witcher (2019–23) before stepping away from the role to honour his commitment to The Witcher novels by Andrzej Sapkowski.

American R&B singer, songwriter and dancer, born in Tappahannock, Virginia. His self-titled 2005 debut at 16 went double platinum on the strength of the No. 1 single "Run It!"; the album F.A.M.E. (2011) won the Grammy Award for Best R&B Album. He has placed more songs on the Billboard Hot 100 than any other male solo artist in history. His career has been shadowed by his 2009 felony assault on his then-girlfriend Rihanna, for which he was convicted and given a five-year probation; the case became a defining moment in the music industry's public conversation about domestic violence.

Spanish tennis player, born in El Palmar, Murcia, and trained from childhood by Juan Carlos Ferrero. In September 2022, at 19, he became the youngest world No. 1 in the history of the ATP rankings — just hours after winning the US Open, his first Grand Slam title. He has since added Wimbledon (2023, 2024 — beating Novak Djokovic in two finals), the French Open (2024) and the US Open again, and is one of three men in the modern era to have won majors on all three surfaces by age 22, alongside Rafael Nadal and Mats Wilander. The torch-passing rivalry with Jannik Sinner is widely held to be the most exciting in men's tennis since Federer–Nadal–Djokovic.

German prince, founder of the University of Wittenberg in 1502 — and, much more famously, the political protector of Martin Luther after the Diet of Worms in 1521. Frederick had Luther kidnapped on the road home from the Diet and hidden, for his own safety, in the Wartburg Castle high above Eisenach, where Luther translated the New Testament from Greek into idiomatic German in only eleven weeks. The two men, oddly, never met in person. Without Frederick the Wise, the early Reformation would in all probability have been smothered in its cradle; Luther would simply have been burned. He died on this day at his castle in Lochau, age 62.

American author and editor, born Francis Brett Harte in Albany, New York. As founding editor of the San Francisco-based Overland Monthly from 1868, he published — in his own pages — the two short stories that defined an entire genre: "The Luck of Roaring Camp" (1868) and "The Outcasts of Poker Flat" (1869). His pithy "local-colour" tales of California Gold Rush miners, gamblers and saloon-keepers were the literary archetypes from which the entire American Western would eventually descend. Mark Twain, originally a friend, came to dislike him with great vigor. Harte spent the last 24 years of his life as a US consul and freelance writer in Europe, dying in Camberley, Surrey at 65.

Soviet chess grandmaster who held the world title across three reigns — 1948–1957, 1958–1960 and 1961–1963 — known to the chess world as "the patriarch of the Soviet chess school." A trained electrical engineer (he held the unusual day job of computer-science researcher) and an unusually rigorous, scientific match-preparer, he founded the Botvinnik chess school whose graduates would dominate the world title for the next half century: Anatoly Karpov, Garry Kasparov and Vladimir Kramnik all studied with him. Born to a Jewish family in Kuokkala, Russia in 1911, he died in Moscow at 83.

South African anti-apartheid leader, mentor and lifelong friend of Nelson Mandela, and Secretary-General of the African National Congress (1949–54). It was Sisulu, two years older and politically a generation senior, who first brought the young attorney Mandela into ANC politics in the 1940s. Convicted with Mandela in the Rivonia Trial in 1964, he served 25 years on Robben Island and at Pollsmoor Prison; released in October 1989, he was Deputy President of the ANC during the historic 1990–94 transition negotiations that produced South Africa's first multi-racial democracy. Mandela called him "a father." He died in Johannesburg at 90.

Indian composer, born in Lucknow on 25 December 1919 — one of the foundational music directors of Hindi cinema and the greatest classical-musical composer of the Indian film industry's golden age. Across about 70 films he wrote some of the most loved scores in Hindi-film history: Anmol Ghadi (1946), Andaz (1949), Aan (1952 — one of India's first Technicolor films), Baiju Bawra (1952, his first Filmfare for Best Music Director), Mother India (1957), Mughal-e-Azam (1960) and Ganga Jamuna (1961). He insisted on using classical Hindustani ragas in popular cinema and persuaded the legendary classical singer Bade Ghulam Ali Khan, who had refused all previous film offers, to sing for Mughal-e-Azam. Awarded the Dadasaheb Phalke Award (1981) and the Padma Bhushan (1992). He died in Mumbai at 86; the Carter Road in Bandra was renamed Sangeet Samrat Naushad Ali Marg in his memory.

American physicist and engineer, born in Los Angeles. On 16 May 1960, in a small lab at Hughes Research Laboratories in Malibu, California, he flashed a high-intensity xenon lamp at a small synthetic ruby crystal — and saw the first coherent beam of laser light ever produced on Earth. The seminal Schawlow-Townes paper had described how a laser ought to work; Maiman was the first to actually build one. Time magazine put his ruby laser on the list of the 100 most influential inventions of the century. The technology now underpins the modern world from supermarket scanners and DVD players to laser eye surgery, fibre-optic internet, missile guidance and the LIGO gravitational-wave detectors. He died in Vancouver, BC at 79.

American businessman, born Irvine Robbins in Winnipeg, Canada and raised in Tacoma, Washington. With his brother-in-law Burt Baskin he founded what became Baskin-Robbins ice-cream parlours in 1945 and merged their separate stores in 1953 — and invented the famous "31 flavours" marketing concept, one for every day of the month, so children could try a new ice cream every day. Today the chain has more than 8,000 stores in some 50 countries. Robbins also pioneered the "free taste" pink-spoon strategy that defined the modern American ice-cream parlour. He died at 90 in Encino, California.

English actor, born in Manchester — only the second person in history (after Bill Paxton) to be in two films that grossed more than a billion dollars worldwide, and remarkably, in two of the most romantic deathbed scenes in modern Hollywood: as Captain Edward J. Smith of the RMS Titanic in James Cameron's Titanic (1997), going down with his ship; and as King Théoden of Rohan in Peter Jackson's The Lord of the Rings: The Two Towers (2002) and The Return of the King (2003), dying in the arms of his niece on the Pelennor Fields. Earlier acclaim for the BBC drama Boys from the Blackstuff (1982) as the unforgettable Yosser Hughes ("Gizza job — go on, gizza job"). He died on 5 May 2024 at age 79, on the morning of the day he was to receive a BAFTA TV Award nomination for The Responder.

In Japan, Kodomo no Hi (こどもの日, Children's Day) is the last day of the country's Golden Week of national holidays. The day was originally Tango no Sekku, a Boys' Day going back about 1,300 years; it was redesignated in 1948 as a holiday for all children. Families fly carp-shaped streamers — koinobori, one for each child — outside their homes, and many display samurai-armour dolls indoors. South Korea has observed Eorininal — Children's Day — on the same date since 1922; it has been a national holiday since 1975. In both countries it is a day for parents to take their children somewhere special.

The annual Dutch national holiday commemorating the German surrender at Wageningen on 5 May 1945, ending five years of occupation. The day is paired with Dodenherdenking — Remembrance of the Dead — on 4 May. Liberation festivals (Bevrijdingsfestivals) are held in fourteen Dutch cities; veterans, including a dwindling number of surviving Canadian liberators whose forces freed most of the country, are guests of honour. Many of the canals and town squares carry the colour of the orange-and-red National Liberation flame.

The Council of Europe's Europe Day, declared in 1964 to commemorate the Council's founding on 5 May 1949 in London. Celebrated across the Council's 46 member states with concerts, debates and the raising of the Council's flag. Distinct from the European Union's own Europe Day on May 9, which marks the 1950 Schuman Declaration.

Observed in the United States on May 5 every year — the anniversary of Alan Shepard's Freedom 7 flight in 1961 — and launched in 2016 by Uniphi Space Agency to thank astronauts and inspire children to look up.
