c. 1917 Compulsory cultivation and forced labour in the Belgian Congo 0 cit. The colonial state imposes compulsory cultivation of crops such as cotton and drafts men to work in mines, on plantations, and on infrastructure.

1917 The great fire and decline of Jewish Salonica 0 cit. A huge fire in 1917 destroyed much of Jewish Salonica, leaving tens of thousands homeless. The city had passed to Greece in 1912, and the new state pressed the Jews to assimilate while many emigrated to France, the United States, and Palestine. The oldest Jewish-majority city in Europe was already shrinking before catastrophe arrived. politics / society ●●

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 ●●

1917 Lenin publishes Imperialism, the Highest Stage of Capitalism 0 cit. Lenin's pamphlet argued that the rich nations had grown wealthy by carving up the world into colonies and spheres of profit, tying capitalism directly to empire. The book gave colonized readers a theory that named their poverty as the flip side of Europe's wealth. Historians point to it as a main reason Marxism-Leninism appealed to anti-colonial thinkers, whatever they made of Soviet politics. economy / politics ●●●

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.

The plan worked: within a year the new Soviet government signed a separate peace at Brest-Litovsk. diplomacy / politics / war ●●●●

c. 1917 German money reaches the Bolsheviks through intermediaries 0 cit. German Foreign Ministry records, later published by historians, show funds channeled toward Bolshevik agitation through middlemen such as Alexander Parvus and the Stockholm banker Olof Aschberg.

It was wartime subversion aimed at Russia's collapse, not ideological sympathy. diplomacy / economy / politics ●●●

April 1917 Trotsky is detained and released on his way to Russia 0 cit. Traveling from New York, Leon Trotsky was pulled off a ship and briefly held by British authorities in Nova Scotia before being allowed to continue to Russia. The episode is a documented fact.

c. November 1917 American businessmen make contact with the new Soviet regime 0 cit. Members of the American Red Cross mission in Russia, including the financier William Boyce Thompson, had contact with revolutionary figures and Thompson personally gave money toward pro-Bolshevik publicity.

Sutton built on such episodes to argue Wall Street actively engineered the revolution; that stronger claim is his, and it is disputed. economy / politics ●●●

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 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 ●●●

6 February 1918 Women over 30 win the vote in Britain 0 cit.

The British government publishes a report, formally titled "Report on the Natives of South-West Africa and Their Treatment by Germany" and known as the Blue Book, compiling sworn testimony from Herero, Nama, and colonial officials on the extermination order, the desert deaths, and the camps.

28 January 1918 Porvenir massacre 0 cit. Texas Rangers of Company B, along with local ranchers and with U.S. Army cavalry nearby, entered the village of Porvenir, separated fifteen unarmed Mexican and Mexican American men and boys, aged sixteen to seventy-two, from the rest of the community, and shot them on a hill outside town. Investigations by Mexican consular officials and the U.S. Army found no evidence the victims were involved in banditry, contradicting the Rangers' claim of a shootout. No Ranger was criminally convicted; Governor William P. Hobby dismissed five Rangers, reassigned others including the company captain, and Company B was disbanded. Historians, including those cited by the Texas State Historical Association, call it the single most notorious documented killing in Ranger history. politics / society ●●●

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.

28 January 1919 Weber Delivers Politics as a Vocation 0 cit. In a lecture to students in Munich, later published as "Politics as a Vocation," the sociologist Max Weber defined the state as the human community that successfully claims a monopoly on the legitimate use of physical force within a given territory. Weber's definition became the standard reference point in political science and sociology for distinguishing legitimate state violence, such as policing and lawful warfare, from illegitimate private violence. The lecture is one of the most cited texts in the modern study of the state and organized force. politics / society ●●●

When most of the Boston police force walked off the job, looting broke out and Governor Calvin Coolidge called out the Massachusetts State Guard to restore order, resulting in several deaths in clashes with crowds.

Labour circulars issued under Governor Edward Northey from 1919 pressed administration officers and police to encourage, and in practice compel, Africans to work on settler farms and public projects.

1919 Forced Labour and the Reserves as Labour Pools 1 cit. In 1919 Governor Edward Northey issued circulars pressing African chiefs and officials to round up men to work on settler farms, a thinly veiled system of forced labour that stirred protest even in Britain.

The reserves were designed to work as reservoirs of cheap labour, crowded enough that people had to leave to survive. economy / politics ●●

c. 1919 The Somali and the Struggle Over Status 0 cit. Kenyan Somalis pressed the colonial state to class them as non-native, alongside Arabs and Asians, seeking to escape the taxes, the kipande pass, and the labour demands imposed on other Africans.

Agents raided speakeasies, breweries, and stills for the next thirteen years, an effort widely criticized at the time and since for chronic underfunding, corruption among agents, and its practical failure to stop the illegal liquor trade. economy / politics ●●

1 February 1920 Royal Canadian Mounted Police created 0 cit. Canada merged the Royal North-West Mounted Police with the federal Dominion Police to form the Royal Canadian Mounted Police, giving the new national force jurisdiction across the whole country rather than just the western territories. The RCMP absorbed the Dominion Police's counter-espionage and federal criminal investigation work, expanding its mandate well beyond frontier policing. politics ●●

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 ●●
