  5. 10 February 1906 HMS Dreadnought launched 0 cit. The Royal Navy launched HMS Dreadnought, the first battleship with an all-big-gun armament and steam turbine propulsion, which made every existing battleship in the world obsolete overnight.

Administrative stations followed at once, ending Embu self-rule and pulling the area into the protectorate, though passive resistance continued for years. politics / war ●●
  10. c. 1906 The disputed scale of the killing contested 0 cit. How many people died in the pacification of central Kenya is genuinely unclear. The most cited figures, running into the thousands, come from Meinertzhagen's diaries and other participant accounts that had reason to exaggerate or to understate. No reliable census of the dead exists, so historians treat the totals as estimates rather than settled facts. society / war ●●
  11. 15 June 1907 Second Hague Peace Conference 0 cit. A larger follow-up conference of 44 states expanded the rules of warfare and arbitration. It reinforced the idea of a codified body of international law governing relations between states. politics / war ●●

  15. 1908 Otenyo, Moraa and the Gusii rising of 1908 0 cit. As British administration pushed into Gusii country, the prophetess Moraa Ng'iti roused resistance and the young warrior Otenyo Nyamaterere speared the district officer G. A. S. Northcote, who survived the wound. The British answered with a punitive expedition that burned villages, seized cattle and killed many Gusii, and Otenyo was later captured and executed.

Otenyo was hunted down, captured, and executed, and he is remembered as a Gusii hero of resistance. politics / society / war ●●●
  17. January 1908 Moraa wa Ngiti inspires the Gusii rising contested 0 cit. Moraa wa Ngiti was a Gusii seer and healer who urged her people to resist the British after troops seized thousands of Gusii cattle in early 1908. Oral history says she blessed the warriors and gave them charms, and inspired her kinsman Otenyo Nyamaterere, who speared and wounded the British officer Northcote. The rising was put down and Otenyo was executed. Her spiritual leadership rests on Gusii oral tradition, so the detail is contested, but the revolt itself is documented. religion / war ●●

  24. 1911 Muhumusa and the Nyabingi resistance 0 cit. The Nyabingi movement of the Uganda-Rwanda borderlands centered on a female spirit, Nyabingi, whose priestesses claimed her power to heal and to command.

  31. 1912 The D-Notice system asks the press to stay quiet 0 cit. Britain set up a joint committee of officials and newspaper editors that issued Defence Notices, requests to the press not to publish material said to endanger national security. The system was voluntary and had no legal force, but editors mostly complied. Supporters called it a sensible partnership; critics called it a polite form of censorship that trained the press to self-silence. politics / war ●●
  32. 1912 The Third Home Rule crisis and the arming of Ulster 0 cit. A third Home Rule Bill passed in 1912 but was fiercely resisted by Ulster unionists, who signed a mass covenant and formed the armed Ulster Volunteers.

Arrested that October and exiled far away to Kisii, she became the enduring symbol of Giriama resistance, her story carried largely through oral tradition. politics / religion / war ●●●
  37. c. 1913 The Dervishes build the fortresses at Taleh 0 cit. After earlier reverses and a period when Britain pulled back to the coast, the Dervish state consolidated in the interior and built stone fortresses at Taleh in the Nugaal valley.

  53. 4 August 1914 The collapse of the Second International 0 cit. When the First World War begins, most socialist parties rally behind their own governments rather than opposing the war as they had pledged. The German Social Democrats' vote for war credits on 4 August 1914 became the symbol of this reversal. The International split along national lines and effectively ceased to function, a betrayal in the eyes of antiwar socialists such as Lenin. diplomacy / politics / war ●●●
  54. 1914 The British state buys into Persian oil 0 cit. The Anglo-Persian Oil Company, formed out of the D'Arcy concession, gained a controlling investment from the British government at the urging of Winston Churchill, who wanted secure fuel for the Royal Navy.

The Giriama refusal to supply labour hardened into open revolt in 1913 and 1914, met with a military campaign that killed hundreds and drove people from their land. Colonial forces razed Kaya Fungo, the sacred forest shrine at the heart of Giriama religion and authority, and imposed a heavy collective fine and demands for carriers for the coming world war. Destroying the kaya was an attack on the community's very identity, meant to break the elders and the spirits who sanctioned resistance. economy / religion / war ●●
  58. 1914 The First World War drains British power 0 cit. The war of 1914 to 1918 cost Britain enormous sums and turned it from the world's leading creditor into a debtor, largely to the United States.

  64. 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 ●●
  65. 9 July 1915 German forces surrender at Khorab 0 cit.

  67. 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 ●●
  68. 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
  69. 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 ●●●
  70. 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.

The gatherings became a seed of the later Communist International. diplomacy / politics / war ●●
  71. 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 ●●●
  72. 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.

  81. 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 ●●
