9 December

A journey through
9 December in history

From a Byzantine general marching into Italy to the day the world agreed to call genocide a crime, 9 December has carried decisions that outlasted the people who made them. This timeline follows the date across the centuries.

THE NINETEENTH CENTURY

The 1800s

Industry, empire, invention, reform and a century of enormous transformation.

Ayacucho ends Spanish rule in South America

On 9 December 1824 a republican army under Antonio José de Sucre, Simón Bolívar’s ablest lieutenant, destroyed the royalist forces of the viceroy José de la Serna on the plain of Quinua, high in the Peruvian Andes. Roughly 6,000 men — Venezuelans, Colombians, Argentines, Chileans and Peruvians — faced an army half as large again, with far more artillery. A cavalry charge led by the Colombian José María Córdova broke the royalist line, and the viceroy signed a capitulation the same day. The victory secured the independence of Peru and, with it, the end of Spanish power on the South American mainland.

Cos asks for terms at Béxar

After weeks of siege and five days of house-to-house fighting in San Antonio de Béxar, General Martín Perfecto de Cos asked the Texan volunteers for surrender terms on the morning of 9 December 1835. Their commander Benjamin Milam had been killed by a sniper two days earlier. Edward Burleson took the Mexican army’s weapons and equipment but let Cos march his men south, because neither side could feed prisoners; the capitulation was signed on 11 December. The withdrawal left San Antonio, and with it the whole of Texas, in Texan hands until Santa Anna returned in the new year.

The first Black governor of a US state

On 9 December 1872 the Louisiana legislature impeached Governor Henry Clay Warmoth, and the lieutenant governor, Pinckney Benton Stewart Pinchback, took over as acting governor. Born free in Georgia to a white planter and a formerly enslaved woman, Pinchback had raised a regiment during the Civil War and risen through Reconstruction politics. He held the office for thirty-six days, until 13 January 1873 — the only African American to serve as governor of a US state until Douglas Wilder was elected in Virginia in 1990.

France separates church and state

The law separating the churches from the state was promulgated in France on 9 December 1905, ending the Concordat of 1801 and the public funding of religion. Shaped in long parliamentary debate by Aristide Briand, Jean Jaurès and Georges Clemenceau, it rests on three ideas: freedom of conscience, the separation of political and religious authority, and the equal treatment of citizens whatever they believe. It remains the foundation of French laïcité more than a century later.

Jerusalem surrenders after four centuries of Ottoman rule

Shortly before nine o’clock on the morning of 9 December 1917 the mayor of Jerusalem, Hussein Salim al-Husseini, walked out of the city under a white flag carrying the Ottoman governor’s letter of surrender. The first British soldiers he met, two sergeants of the London Regiment scouting ahead of the main force, refused to take it; the letter was eventually accepted by a brigade commander. Four hundred years of Ottoman rule ended that morning. General Edmund Allenby made his formal entry two days later, dismounting and walking through the Jaffa Gate on foot, and read a proclamation placing the city under martial law while guaranteeing its holy places.

The Doctors’ Trial opens at Nuremberg

On 9 December 1946 an American military tribunal at Nuremberg opened proceedings against twenty-three German physicians and medical administrators, the first of the twelve trials that followed the main international case. The charges concerned experiments and medical procedures inflicted on prisoners and civilians. Sixteen defendants were convicted in August 1947 and seven, including Karl Brandt, were executed. The judgment set out ten principles for experiments on human beings, including voluntary consent, which became known as the Nuremberg Code.

The world agrees to call genocide a crime

On 9 December 1948 the United Nations General Assembly adopted the Convention on the Prevention and Punishment of the Crime of Genocide, by resolution 260 A (III). It was the first human rights treaty the Assembly ever adopted, and it committed the states that joined it to prevent and punish a crime that had no name in law a decade earlier. The word itself had been coined in 1944 by the Polish-Jewish lawyer Raphael Lemkin, who campaigned for the treaty for the rest of his life. The convention came into force on 12 January 1951. Since 2015 the United Nations has kept 9 December as a day of commemoration for its victims.

Coronation Street reaches the screen

The first episode of Coronation Street went out on 9 December 1960, made by Granada Television in Manchester for the ITV network. Tony Warren, then twenty-four, had written it and would write the first thirteen episodes; the opening half-hour introduced Florrie Lindley taking over the corner shop and Ken Barlow falling out with his father. The reviews were unkind — one newspaper called the programme doomed the next morning — but it went out twice a week from the start and became the longest-running television soap opera in the world.

Tanganyika becomes independent

Tanganyika became independent of Britain on 9 December 1961, with Julius Nyerere as its first prime minister. His party, the Tanganyika African National Union, had swept the Legislative Council elections of 1960, and the transfer of power came without the long armed struggle seen elsewhere in Africa. Nyerere stepped down the following month to think and write about government and African unity, returning as president when Tanganyika became a republic in 1962. In April 1964 the country joined with Zanzibar; by October that year it had been renamed the United Republic of Tanzania.

The Mother of All Demos

On 9 December 1968 Douglas Engelbart sat on a stage in San Francisco and, in ninety minutes, showed an audience of computer professionals almost everything a modern computer does. Working with seventeen colleagues from the Augmentation Research Center at Stanford Research Institute, he demonstrated the mouse, windows, hypertext links, cut-and-paste editing, two people editing the same document at once, and video conferencing. The machine itself was thirty miles away in Menlo Park. Engelbart’s team, led by Bill English, had spent months building a microwave link and camera rig so the audience could watch the screen live. The event became known as the Mother of All Demos.

Smallpox is certified eradicated

On 9 December 1979 the members of the Global Commission for the Certification of Smallpox Eradication, an independent panel of scientists from nineteen countries, signed a statement at the World Health Organization in Geneva declaring that smallpox had been eradicated from the world. The campaign had begun in earnest in 1967, combining mass vaccination with relentless tracing of every case. The last known naturally occurring case was in Somalia in 1977. In May 1980 the World Health Assembly made the formal declaration that the world was free of the disease — the only human disease ever eliminated.
