What happened on December 10?
Martin Luther Burns the Papal Bull in Wittenberg
On December 10, 1520, German reformer Martin Luther publicly burned the papal bull Exsurge Domine outside the Elster Gate in Wittenberg. The document, issued by Pope Leo X, had condemned 41 of Luther’s propositions and threatened him with excommunication. By tossing the bull, along with volumes of canon law, into the flames, Luther made a defiant and very visible break with papal authority. The act signaled that the conflict with Rome was no longer an internal church dispute but a full-fledged Reformation that would reshape European religion and politics.
Isaac Newton Elected Fellow of the Royal Society
On December 10, 1684, Isaac Newton was elected a Fellow of the Royal Society in London. At the time, Newton was already known among scholars for his groundbreaking work on optics and mathematics, though Philosophiæ Naturalis Principia Mathematica was still a few years away. Membership in the Royal Society plugged him into one of the most vibrant scientific networks in Europe, giving his ideas a powerful platform. His election helped cement the Society’s role as a home for experimental science and advanced mathematical physics during the Scientific Revolution.
Encyclopædia Britannica Begins Publication in Edinburgh
On December 10, 1768, the first installment of the original three-volume Encyclopædia Britannica was published in Edinburgh, Scotland. Conceived by printer Colin Macfarquhar and engraver Andrew Bell, with William Smellie as editor, the work aimed to gather human knowledge into a single, organized reference. Issued in weekly parts, it blended scholarly authority with practical articles on everything from philosophy to shipbuilding. Over the centuries, the encyclopedia became a cultural icon of the Enlightenment ideal that knowledge could be systematically collected, edited, and shared with a wide reading public.
Mississippi Becomes the 20th U.S. State
On December 10, 1817, Mississippi was formally admitted to the Union as the 20th state. The territory, carved from lands formerly claimed by European empires and seized from Native nations, had grown rapidly on the back of cotton cultivation and enslaved labor. Statehood gave Mississippi full representation in Congress and greater control over its own laws, including those enforcing slavery. Its admission foreshadowed intensifying debates over the expansion of slave and free states that would dominate American politics in the decades before the Civil War.
First Gas-Lit Traffic Lights Installed in London
On December 10, 1868, the world’s first known traffic lights were installed outside the Houses of Parliament in London. Designed by railway engineer J. P. Knight, the signal used gas-lit arms and colored lamps to control horse-drawn traffic at the busy junction of Great George Street and Bridge Street. Policemen operated the system manually, switching between “stop” and “caution” indications using semaphore-style arms by day and red and green lights by night. Although a gas explosion in 1869 ended this particular experiment, the idea of signaling road traffic took hold and evolved into the electric traffic lights that define modern city streets.
First Nobel Prizes Awarded in Stockholm and Oslo
On December 10, 1901, the first Nobel Prizes were awarded, fulfilling the will of Swedish inventor Alfred Nobel five years after his death. Ceremonies in Stockholm honored laureates in Physics, Chemistry, Medicine, and Literature, while the Peace Prize was presented in Oslo. Early recipients included Wilhelm Conrad Röntgen for his discovery of X-rays and Henry Dunant, co-founder of the Red Cross, for humanitarian work. The annual awards, timed to the anniversary of Nobel’s death, quickly became a global benchmark of achievement in science, culture, and efforts toward peace.
Theodore Roosevelt Receives the Nobel Peace Prize
On December 10, 1906, former U.S. President Theodore Roosevelt was formally awarded the Nobel Peace Prize in Oslo for mediating the Treaty of Portsmouth, which ended the Russo-Japanese War. Roosevelt had brokered negotiations between Russia and Japan in 1905, helping avert a deeper conflict in East Asia. The 1906 ceremony made him the first American to receive any Nobel Prize and the first sitting U.S. president to be named a laureate, though he did not travel to Norway and sent a representative instead. His award underscored how personal diplomacy and back-channel negotiations were emerging as tools of international statecraft in the early 20th century.
First U.S. Christmas Seals Sold to Fight Tuberculosis
On December 10, 1907, the first American Christmas Seals went on sale at the Wilmington, Delaware post office. Emily Bissell, inspired by a Danish campaign, designed and promoted the decorative stamps to raise money for a local tuberculosis sanatorium. Sold for a penny apiece and attached to holiday mail, the seals caught the public’s imagination and raised far more than the modest original goal. The success turned Christmas Seals into a nationwide fundraising tradition that supported tuberculosis prevention and, later, broader public health efforts.
The “Grand Ole Opry” Gets Its Name on Nashville Radio
On December 10, 1927, Nashville announcer George D. Hay first used the phrase “Grand Ole Opry” on the air to introduce WSM’s weekly country music program. The show had been broadcasting live “barn dance” music since 1925, but Hay’s off-the-cuff contrast between the classical program that preceded it and the down-home tunes that followed gave the show its enduring title. Under the new name, the Grand Ole Opry grew into the flagship showcase for country music, elevating performers from Hank Williams to Dolly Parton. The rebranding on that December evening helped anchor Nashville’s identity as “Music City” in the American imagination.
Edward VIII Signs Instruments of Abdication
On December 10, 1936, Britain’s King Edward VIII signed the instruments of abdication at Fort Belvedere, effectively giving up the throne. Under intense political pressure over his determination to marry American divorcée Wallis Simpson, Edward chose to step aside rather than provoke a constitutional crisis in the United Kingdom and the Dominions. The documents were also signed by his three younger brothers, clearing the way for his brother Albert to become King George VI. The abdication reshaped the modern British monarchy and set the stage for the reign of George VI and, later, Queen Elizabeth II.
HMS Prince of Wales and Repulse Sunk off Malaya
On December 10, 1941, just days after the attack on Pearl Harbor, Japanese aircraft sank the British battleship HMS Prince of Wales and the battlecruiser HMS Repulse off the coast of Malaya. Operating without air cover, the ships of Force Z were overwhelmed by torpedo bombers launched from bases in French Indochina. The loss cost Britain two of its most powerful capital ships and more than 800 sailors’ lives in a single engagement. The sinking demonstrated conclusively that naval air power could destroy even heavily armored battleships at sea, accelerating a shift in World War II strategy toward carriers and aircraft.
United Nations Adopts the Universal Declaration of Human Rights
On December 10, 1948, the United Nations General Assembly adopted the Universal Declaration of Human Rights in Paris. Drafted under the leadership of Eleanor Roosevelt and a diverse committee of jurists and diplomats, the text set out a broad catalog of civil, political, economic, social, and cultural rights. Although it is not a binding treaty, the vote—48 in favor, none against, with eight abstentions—signaled an international commitment to a shared standard of human dignity in the shadow of World War II and the Holocaust. December 10 later became observed as Human Rights Day, and the declaration has influenced constitutions, court decisions, and human-rights movements around the globe.
Ralph Bunche Becomes First Black Nobel Laureate
On December 10, 1950, American diplomat Ralph Bunche received the Nobel Peace Prize in Oslo for his mediation in the first Arab–Israeli war. Working as a United Nations official, Bunche had negotiated the 1949 armistice agreements between Israel and neighboring Arab states on the island of Rhodes. The Oslo ceremony recognized his quiet, meticulous style of diplomacy and his commitment to multilateral solutions through the UN. As the first Black person to receive a Nobel Prize, Bunche’s honor also carried powerful symbolic weight in the era of emerging civil rights movements.
Winston Churchill Accepts the Nobel Prize in Literature
On December 10, 1953, former British Prime Minister Winston Churchill formally received the Nobel Prize in Literature in Stockholm. The Swedish Academy honored him “for his mastery of historical and biographical description as well as for brilliant oratory,” recognizing not only his speeches but also his multi-volume histories and memoirs. Too ill to attend in person, Churchill sent a written address that was read at the ceremony, reflecting on language as a tool of leadership in dark times. The occasion highlighted how his words, as much as his wartime decisions, had shaped public morale during World War II.
Martin Luther King Jr. Receives the Nobel Peace Prize
On December 10, 1964, civil rights leader Martin Luther King Jr. accepted the Nobel Peace Prize in Oslo. At 35, he was one of the youngest laureates ever, honored for his leadership of a nonviolent movement challenging racial segregation and discrimination in the United States. In his acceptance speech, King framed the award not as a personal triumph but as recognition of a broad struggle “for civil rights and a better world,” linking the American civil rights movement to global fights against poverty and war. The ceremony amplified his moral authority at home and abroad, even as the U.S. wrestled with violent backlash to desegregation and voting-rights campaigns.
Soul Singer Otis Redding Dies in Wisconsin Plane Crash
On December 10, 1967, 26-year-old soul singer Otis Redding was killed when his chartered plane crashed into Lake Monona near Madison, Wisconsin. Redding, along with most members of the Bar-Kays band, was en route to a television appearance after a string of successful shows. Just days earlier he had recorded “(Sittin’ On) The Dock of the Bay,” a song that would become his first posthumous number-one hit and a classic of American music. His sudden death cut short a rising career but left a deep influence on soul, rock, and R&B artists who drew on his raw, emotive vocal style.
Zanzibar Gains Independence from Britain
On December 10, 1963, the island of Zanzibar, off the coast of East Africa, gained independence from the United Kingdom. The former British protectorate became a constitutional monarchy under Sultan Jamshid bin Abdullah, ending decades of formal colonial rule. Independence celebrations filled the streets of Zanzibar Town with parades, music, and flags reflecting a mix of Arab, African, and South Asian influences. Within months, political upheaval would topple the sultanate and lead to Zanzibar’s union with mainland Tanganyika, forming the United Republic of Tanzania in 1964.
Raúl Alfonsín Sworn In, Restoring Democracy in Argentina
On December 10, 1983, Raúl Alfonsín took the oath of office as president of Argentina, marking the country’s return to constitutional democracy after a brutal military dictatorship. Crowds packed the Plaza de Mayo in Buenos Aires as the new civilian leader promised accountability for the “Dirty War,” during which thousands of people were disappeared. Alfonsín’s government soon established the National Commission on the Disappearance of Persons and initiated trials of former junta leaders. His inauguration became a touchstone for democratic transitions across Latin America in the 1980s.
Desmond Tutu Receives the Nobel Peace Prize
On December 10, 1984, Anglican bishop Desmond Tutu accepted the Nobel Peace Prize in Oslo for his nonviolent opposition to apartheid in South Africa. As a church leader, Tutu had used sermons, speeches, and international advocacy to highlight the daily injustices of white minority rule. The Nobel Committee cited his “role as a unifying leader figure” in the struggle, at a time when the apartheid regime still held firm. The award brought greater global pressure on Pretoria and elevated Tutu as a moral voice in the long campaign that would eventually dismantle apartheid.
Mandela and de Klerk Share the Nobel Peace Prize
On December 10, 1993, Nelson Mandela and South African President F. W. de Klerk jointly received the Nobel Peace Prize in Oslo. The Nobel Committee honored them for their “work for the peaceful termination of the apartheid regime” and for laying the groundwork for multiracial elections. Mandela, recently released from 27 years in prison, symbolized the hope of a democratic South Africa, while de Klerk represented the white minority that had chosen negotiation over continued repression. The ceremony came just months before South Africans would vote in April 1994, electing Mandela as the country’s first Black president.
Mandela Signs South Africa’s New Democratic Constitution
On December 10, 1996, President Nelson Mandela signed South Africa’s new constitution at a ceremony in Sharpeville. The location was chosen deliberately: in 1960, police had opened fire on protesters there, killing dozens in a massacre that became a symbol of apartheid’s brutality. The new constitution entrenched a broad bill of rights, universal suffrage, and an independent constitutional court, replacing the legal framework that had propped up racial segregation. By signing it on International Human Rights Day, Mandela underlined the country’s intent to anchor its future in equality and the rule of law.
Jimmy Carter Honored with the Nobel Peace Prize
On December 10, 2002, former U.S. President Jimmy Carter accepted the Nobel Peace Prize in Oslo for decades of work in conflict resolution, human rights, and public health. Through the Carter Center, he had monitored elections, mediated disputes, and helped wage campaigns against diseases such as Guinea worm. The Nobel Committee explicitly cited his role in the 1978 Camp David Accords between Egypt and Israel as well as his “untiring effort” to find peaceful solutions after leaving office. The award highlighted how an ex-president could wield soft power through diplomacy, advocacy, and hands-on humanitarian projects.
Inventors of the Blue LED Receive the Nobel Prize in Physics
On December 10, 2014, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura were awarded the Nobel Prize in Physics in Stockholm for inventing efficient blue light-emitting diodes. Their work in the late 20th century had solved a long-standing materials challenge by creating bright blue LEDs based on gallium nitride semiconductors. Combined with red and green LEDs, their innovation enabled white LED lamps that use far less energy and last far longer than traditional bulbs. By the time of the ceremony, blue-LED-based lighting had already begun transforming everything from household lamps to smartphone screens and city streetlights.
Empty Chair Marks Liu Xiaobo’s Nobel Peace Prize
On December 10, 2010, an empty chair stood on the stage in Oslo’s City Hall as the Nobel Peace Prize was awarded to Chinese writer and dissident Liu Xiaobo. Liu, imprisoned in China for his role in drafting the pro-democracy manifesto Charter 08, was unable to attend, and neither his family nor colleagues were allowed to travel to Norway. During the ceremony, the Nobel Committee symbolically placed his diploma on the vacant seat, underscoring the costs of political dissent under authoritarian rule. The image of the empty chair spread worldwide and became a potent visual reminder of ongoing struggles for freedom of expression in China and beyond.
