Between about 1913 and 1918 colonial forces ran repeated punitive expeditions across the north Rift, seizing livestock and weapons from pastoralists. The first disarmament campaign in what is now northwest Kenya came in 1914. Pokot fighters were at times used to help the British against the Turkana, then were themselves subjected to cattle confiscation and control of their movement. politics / war ●●

August 1914 Taveta is occupied in the East Africa campaign 3 cit. German forces occupied Taveta at the start of the First World War in East Africa, making Taita-Taveta a front-line corridor between the coast, Kilimanjaro and the railway interior.

19 January 1915 Germany begins Zeppelin bombing raids on Britain 0 cit. German airships attacked English towns in the first strategic bombing raids against a home population, killing civilians far from the front lines. The raids, and later Gotha bomber attacks, brought the war directly to British cities for the first time and forced Britain to develop dedicated home air defenses. The psychological shock of bombing civilians from the air shaped military and public thinking about air power for decades. technology / war ●●

9 July 1915 German forces surrender at Khorab 0 cit. The remaining German colonial garrison surrendered unconditionally to South African forces under General Louis Botha, ending German rule over the territory. South Africa administered the territory under martial law in the immediate aftermath. German colonial administration in South-West Africa never resumed after the war. war ●●

c. January 1915 Plan de San Diego and the start of border violence 0 cit. A manifesto known as the Plan de San Diego, calling for an uprising to reclaim the Southwest for Mexico and killed on discovery, circulated among ethnic Mexican radicals in South Texas, and sporadic raids by Mexican and Tejano insurgents followed against Anglo ranches and rail lines. Texas authorities, ranchers, and Rangers responded with a campaign of reprisal that killed far more people than the raids themselves. Historians including Doug Swanson and Monica Muñoz Martinez identify this as the opening of the period later called La Matanza. politics / war ●●

8 August 1915 Rangers killed in the Norias raid 0 cit. A raiding party linked to the Plan de San Diego insurgency attacked the King Ranch's Norias division; Rangers, ranch hands, and U.S. soldiers repelled the raid, killing most of the raiders. The attack was cited by Rangers and ranchers to justify the escalating campaign of reprisal killings against ethnic Mexican civilians that followed, even though most victims of that reprisal campaign had no connection to the raid. war ●

c. 1 January 1915 Texas Rangers' La Matanza and Anti-Mexican Lynchings 0 cit. Between roughly 1915 and 1919, Texas Rangers, local police, and vigilante mobs killed Mexicans and Mexican Americans in South Texas following the Plan de San Diego uprising, a period historians call La Matanza (the killing). Historians William D. Carrigan and Clive Webb documented hundreds of confirmed lynchings of people of Mexican origin in the US Southwest between 1848 and 1928, while historian Monica Muñoz Martinez estimates the death toll of La Matanza alone in the hundreds to low thousands, noting many killings went unrecorded. This period has its own dedicated timeline elsewhere; it is noted here briefly because it forms the backdrop for the Porvenir massacre and other violence covered in this dataset. politics / society / war ●●●

5 September 1915 The Zimmerwald Conference 0 cit. Antiwar socialists from both warring camps meet secretly in the Swiss village of Zimmerwald and issue a manifesto calling for a peace without annexations. A minority known as the Zimmerwald Left, led by Lenin, argued instead for turning the imperialist war into civil war and revolution. The gatherings became a seed of the later Communist International. diplomacy / politics / war ●●

24 April 1915 to 1917 The Armenian genocide 0 cit. The Ottoman government carried out the systematic deportation and mass killing of its Armenian population, along with Assyrian and Greek communities. Around one to one and a half million Armenians died through massacres, death marches, and starvation. It is documented as genocide by historians and many governments. The modern Turkish state disputes the term and the intent; that position is a denial of an established historical fact, not a competing account of it. politics / society / war ●●●

24 April 1915 Arrest of Armenian intellectuals in Constantinople 0 cit. Ottoman authorities round up several hundred Armenian community leaders, writers, and professionals in the capital, most of whom are later killed. The date, 24 April 1915, is commemorated worldwide as Armenian Genocide Remembrance Day. The arrests mark the start of the systematic destruction of the Ottoman Armenian community. politics / war ●●●

23 January 1915 John Chilembwe's rising in Nyasaland 0 cit. John Chilembwe, an American-educated Baptist minister, led an armed rising against British rule, protesting land dispossession, harsh plantation labor, and the drafting of Africans to fight in the First World War. His preaching fused Christian conviction with a demand for African dignity and justice. The revolt was quickly crushed and Chilembwe was killed, but he became a founding figure of Malawian nationalism. politics / religion / war ●●●

c. 1915 Britain turns to America to finance the Great War 0 cit. To pay for the First World War, Britain borrowed heavily in the United States, with the bank J.P. Morgan acting as its purchasing agent for American munitions and supplies. The world's greatest creditor nation was becoming a debtor, and Adam Tooze argues in The Deluge that this dependence quietly shifted financial power across the Atlantic. diplomacy / economy / war ●●●

c. 1916 German Rhodes Scholarships suspended 0 cit. The Rhodes Trust suspended the German scholarships as Britain and Germany fought each other in the First World War. The suspension showed how quickly a scheme built to bind elites together could be overridden by war between their states. German scholars would not return to Oxford under the program for over a decade. diplomacy / war ●

18 June 1916 National Guard mobilized for the Mexican border 0 cit. After Pancho Villa's raid on Columbus, New Mexico, President Wilson mobilized roughly 110,000 National Guard troops from every state to patrol the border alongside General John Pershing's Punitive Expedition into Mexico. The call-up was the largest mobilization of the Guard since the Civil War and served as a dress rehearsal for the much larger mobilization that followed a year later for World War I. It exposed continuing gaps in Guard training, equipment, and readiness for sustained federal service. diplomacy / war ●●

3 June 1916 National Defense Act of 1916 0 cit. Congress passed the National Defense Act of 1916, which expanded the Regular Army and National Guard, required Guard members to take a dual oath to their state and to the United States, and gave the president clearer authority to draft the Guard into federal service. The law strengthened federal control and standardization of the Guard while preserving its state militia character. It set the basic dual state-federal structure that still defines the National Guard. politics / war ●●●

June 1916 to 1918 The Arab Revolt 0 cit. Backed by Britain, Sharif Hussein of Mecca leads an Arab uprising against Ottoman rule, aided by officers including T. E. Lawrence. The revolt helped break Ottoman control of the Arab provinces. Arab leaders believed they were promised independence, a promise that clashed with secret Allied plans to divide the region. diplomacy / politics / war ●●

c. 1916 The Carrier Corps and the toll of the First World War 0 cit. During the First World War Britain conscripted hundreds of thousands of Africans from the protectorate as porters in the Carrier Corps to supply the campaign against German East Africa. Tens of thousands died of disease, hunger, and exhaustion, with estimates commonly ranging from around 50,000 upward, though records were poorly kept and the true toll is uncertain. The Nairobi district of Kariokor takes its name from the Carrier Corps depot. society / war ●●

24 April 1916 The Easter Rising and the executed leaders 0 cit. A group of republicans seized buildings in Dublin at Easter 1916 and proclaimed an Irish Republic, holding out for about a week before surrendering. The rising had little popular support at first, but the British execution of sixteen leaders, including Patrick Pearse and James Connolly, turned public opinion sharply. It transformed the mood of the country and pushed nationalist opinion toward full independence. politics / war ●●●

6 April 1917 United States enters the war 0 cit. Unrestricted submarine warfare and the Zimmermann telegram bring the United States into the war on the Allied side. politics / war ●●●●

April 1917 Agreement of Saint-Jean-de-Maurienne 0 cit. Secret understanding among Britain, France, and Italy promising Italy a zone in southwestern Anatolia after the Ottoman defeat. The Allies later voided it, deepening Italian grievances at the peace conference. diplomacy / politics / war ●●

1917 The Espionage and Sedition Acts jail wartime dissent 0 cit. The Espionage Act of 1917 and the Sedition Act of 1918 are used to imprison anti-war speakers, including socialist leader Eugene Debs. The Espionage Act remains the law under which leakers and publishers are still charged a century later. politics / war ●●●●

18 May 1917 US Selective Service Act of 1917 0 cit. The United States reintroduced national conscription for the first time since the Civil War, registering nearly 24 million men and eventually drafting about 2.8 million to fight in the First World War. Local draft boards administered registration and selection, a decentralized structure carried into later 20th-century American conscription. It marked the emergence of the United States as a mass-mobilization military power. politics / war ●●

5 August 1917 National Guard federalized for World War I 0 cit. President Wilson drafted the entire National Guard into federal service, folding its roughly 380,000 members into the American Expeditionary Forces. National Guard divisions, including the 26th 'Yankee' Division and the 42nd 'Rainbow' Division, saw extensive combat on the Western Front in 1918. The mobilization confirmed the Guard's status as a primary federal reserve force rather than a purely local defense body. war ●●●

c. 1917 Confidential and secret markings enter military paper 0 cit. During the First World War the armies of Europe and the United States began stamping documents with a graded scale of secrecy, borrowing French practice that ranked papers from confidential up to the most guarded. This was the seed of the modern classification hierarchy. What started as battlefield practice slowly hardened into a permanent bureaucracy of stamps and rules. politics / war ●●

April 1917 The United States enters the First World War 0 cit. The United States declared war on Germany and began lending directly to Britain and France on a vast scale, replacing the private loans that had funded the Allied war effort. American money and manpower helped decide the war and left the European victors owing large war debts to Washington. diplomacy / economy / war ●●●

April 1917 Germany finances Lenin's return to Russia 0 cit. The German government arranged and paid for Lenin and other Bolshevik exiles to cross wartime Germany in a sealed railway carriage and reach Russia. Berlin hoped a Bolshevik seizure of power would pull Russia out of the First World War. The plan worked: within a year the new Soviet government signed a separate peace at Brest-Litovsk. diplomacy / politics / war ●●●●

8 January 1918 Wilson's Fourteen Points 0 cit. President Woodrow Wilson set out fourteen principles for peace in an address to Congress, including open diplomacy, free trade, and a general association of nations. His wartime rhetoric of a world made safe for democracy shaped the postwar settlement. politics / war ●●●●

3 November 1918 Kiel Mutiny 0 cit. German sailors at Kiel mutinied rather than obey orders for a final, likely suicidal, sortie against the British fleet in the war's last days. The mutiny spread rapidly to other ports and cities, triggering the German Revolution that toppled the Kaiser within days. It stands as one of the clearest cases of a navy's rank and file refusing an order that precipitated the collapse of a regime. politics / war ●●●

1 June 1918 Battle of Belleau Wood 0 cit. U.S. Marines helped halt a German advance toward Paris in brutal, weeks-long fighting through the forest at Belleau Wood, suffering heavy casualties. The battle became one of the founding legends of the modern Marine Corps and is credited with the nickname 'Devil Dogs,' allegedly given by German soldiers. It remains one of the most commemorated engagements in Marine Corps history. war ●●

1 April 1918 Royal Air Force founded as an independent service 0 cit. Britain merged the Royal Flying Corps and Royal Naval Air Service to form the Royal Air Force, the world's first air force independent of army or navy command. Its founding was driven partly by the shock of German bombing raids on London and the belief that air power needed unified command. The RAF's structure became a model later copied by other nations building independent air services. politics / war ●●●

30 October 1918 Armistice of Mudros and Allied occupation 0 cit. The Ottomans sign an armistice ending their part in World War I, and Allied forces soon occupy Istanbul and much of Anatolia. The government in the capital is reduced to a figurehead under foreign control. The occupation set the stage for a nationalist resistance movement in the interior. diplomacy / politics / war ●●

1918 to 1921 Civil-war pogroms kill tens of thousands in Ukraine 0 cit. During the Russian Civil War, Jewish communities in Ukraine suffered a wave of pogroms far deadlier than those of the 1880s. Forces on many sides took part, including troops loyal to the Ukrainian leader Symon Petliura, White armies, and peasant bands. Historians estimate the massacres killed tens of thousands of Jews, with some counts running higher, in a foretaste of worse to come. politics / society / war ●●

28 May 1918 to 1920 First Republic of Armenia 0 cit. As the Russian and Ottoman empires collapse, Armenians in the former Russian territory declare an independent republic centered on Yerevan. The young state struggles with war, famine, and masses of genocide refugees, and its promised borders under the 1920 Treaty of Sèvres never take effect. Squeezed between Turkish nationalist forces and the advancing Red Army, it lasts barely two years before being sovietized. politics / war ●●

c. 1918 The disarmament and pacification of Turkana 5 cit. A series of military patrols through the late 1910s and 1920s broke Turkana resistance, seized firearms and huge numbers of livestock, and left the community disarmed among armed and raiding neighbours. The campaigns treated the Turkana as a problem to be subdued rather than a people to be governed and served. Turkana was then left largely without schools, roads, or administration for decades. politics / war ●●

1919 Treaty of Versailles restricts Krupp arms production 0 cit. The 1919 Treaty of Versailles sharply limited German arms manufacture, forcing Krupp to shift to civilian products. The firm quietly kept some weapons design work alive during the 1920s. politics / war ●●

1919 Mussolini's National Fascist Party takes its name and emblem from the fasces 0 cit. Benito Mussolini's movement adopts the fasces as its namesake symbol, and the party takes the name 'Fascism' from it, permanently associating the ancient Roman emblem in the 20th-century public mind with Italian Fascism, even though the symbol continued to appear unrelated on older American civic monuments predating this association. politics / war ●●

13 April 1919 Jallianwala Bagh massacre in Amritsar 0 cit. British troops under General Dyer fired on an unarmed crowd trapped in an enclosed garden, killing hundreds. The massacre shocked Indian opinion and destroyed much remaining faith in British rule. It pushed many moderates, including Gandhi, toward outright demands for independence. politics / war ●●

12 September 1919 to 1920 D'Annunzio seizes Fiume 0 cit. The poet Gabriele D'Annunzio leads war veterans to occupy the disputed city of Fiume and rules it for over a year.

January 1919 The First Dáil and the War of Independence 0 cit. After a landslide win in the 1918 election, Sinn Féin members refused to sit at Westminster and set up their own parliament, the First Dáil, in January 1919.

The conflict, marked by ambushes and reprisals including the Black and Tans, lasted until a truce in July 1921. politics / war ●●●

1919 The American Black Chamber 0 cit. Herbert O. Yardley set up a secret US code-breaking bureau, funded by the State and War Departments, that read the encrypted cables of foreign governments.

Secretary of State Henry Stimson shut it down in 1929, reportedly saying that gentlemen do not read each other's mail. diplomacy / politics / war ●●

1919 The Soldier Settlement Scheme After the Great War 0 cit. After the First World War the government threw open highland land to British ex-servicemen through a lottery scheme, hoping to plant a larger, loyal white population. Thousands of new farms were carved out, many on land recently used by Africans, and the European population climbed sharply. The scheme deepened the alienation of African land and sharply increased the demand for squatter and wage labour to work the new farms. economy / politics / war ●●

4 June 1920 Treaty of Trianon 0 cit. Peace treaty with Hungary that transferred about two thirds of its prewar territory to neighboring states. It left large Hungarian minorities abroad and remains a national grievance. diplomacy / politics / war ●●●

c. March 1920 The Black and Tans recruited for Ireland 0 cit. As the Irish War of Independence spread, Britain recruited demobilized First World War soldiers to reinforce the depleted RIC, and shortages of uniforms left them in a mix of dark police and khaki army dress that earned the nickname Black and Tans. Loosely disciplined and often violent, they became notorious for reprisals against civilians and property. Their name endures in Ireland as shorthand for the brutality of paramilitary policing. politics / society / war ●●●

c. July 1920 The Auxiliary Division formed within the RIC 0 cit. Separate from the Black and Tans, the Auxiliary Division of the RIC was recruited from former British Army officers and organized into mobile companies to hunt the Irish Republican Army. Better paid and more heavily armed, the Auxiliaries operated with wide latitude and were tied to some of the war's most notorious reprisals. Together with the Black and Tans they came to symbolize Britain using ex-soldiers as a militarized police against an insurgency. politics / war ●●

21 November 1920 Bloody Sunday in Dublin 0 cit. On the morning of 21 November 1920 IRA units killed a group of British intelligence officers in Dublin. That afternoon, RIC forces including Auxiliaries and Black and Tans opened fire on the crowd at a Gaelic football match at Croke Park, killing fourteen civilians. The day became a defining atrocity of the war and a lasting example of how armed police reprisals fell on ordinary people. politics / society / war ●●

10 August 1920 Treaty of Sèvres and the partition 0 cit. The Allies impose a treaty that strips the empire of its Arab lands and much of Anatolia, handing territory to Greece, Italy, France, and proposed Armenian and Kurdish states. The terms were so harsh they galvanized the nationalist movement, which rejected the treaty and fought to overturn it. Sèvres was never fully carried out. diplomacy / politics / war ●●

1920 The Ulster Special Constabulary is raised in Northern Ireland 0 cit. Britain formed the Ulster Special Constabulary, whose part-time B Specials became a mostly Protestant armed home force during the Irish conflict. Unionists saw them as local defence against the IRA, while Catholics and nationalists saw a partisan force turned against their community. The B Specials were disbanded in 1970 after the Hunt Report, an early sign of how a loyalist home guard can deepen a divide (cross-referenced with the Northern Ireland thread). politics / war ●●

c. 1920 The Kipsigis and Other Kalenjin Lose Land 5 cit. The Kipsigis and neighbouring Kalenjin communities of Sotik and Kericho were pushed off grazing and farming land so the cool uplands could be planted with tea and settler crops. The 1905 Sotik punitive expedition was the violent hinge: a British force under Major L. R. H. Pope-Hennessy, using King's African Rifles, police, levies and machine guns, punished the Sotik/Kipsigis, seized cattle, and opened land for colonial control. Large tea estates later rose on ground that had carried cattle and millet. economy / politics / war ●●●●

January 1920 British aerial bombardment ends the Dervish State 0 cit. In early 1920 Britain used the newly formed Royal Air Force to bomb the Dervish fortresses at Taleh, combined with ground columns of the Camel Corps. The air campaign broke the Dervish state within weeks after twenty years of resistance. Sayyid Mohammed Abdullah Hassan fled to the Ogaden and died later that year, most accounts say of illness. He is remembered as an early hero of Somali nationalism. politics / technology / war ●●●

c. 1920 Timau soldier settlers take farms on the Nanyuki edge 3 cit. Archival settler databases record Timau farms taken by post-First World War soldier settlers, including James Scott at Farm 882 and Lionel Hickson at Embori. Hickson drew Embori under the Soldier Settlement Scheme and moved there in 1920; later accounts describe the farm as a 3,000-acre Timau holding at about 8,500 feet, later enlarged. This places Timau inside the same soldier-settler highland geography as Nanyuki and Laikipia. economy / politics / war ●●●●

6 December 1921 Anglo-Irish Treaty 0 cit. Agreement ending the Irish War of Independence and creating the Irish Free State as a dominion, with Northern Ireland able to opt out. The split over its terms led to the Irish Civil War. diplomacy / politics / war ●●●

24 May 1921 The Bulhoek massacre 0 cit. When Enoch Mgijima's Israelites refused police orders to leave their settlement, South African police opened fire and killed around 160 to 200 believers, most armed only with knobkerries and faith. The massacre showed how far the state would go against a religious community that would not submit. It became a lasting symbol of the violence at the heart of colonial and settler rule. politics / religion / war ●●

The major naval powers, the United States, Britain, Japan, France, and Italy, agreed to fixed tonnage ratios for capital ships and a ten-year halt on new battleship construction, the first major international arms-control treaty of the industrial era.

May 1922 Bondelswarts Rebellion and aerial bombing 0 cit. South African administrator Jan Christiaan Smuts' government imposed a heavy dog tax on the Bondelswarts Nama community, provoking an armed protest that South African authorities crushed using aircraft to bomb and strafe Nama encampments.
