ON THIS DAY · 16 MAY 1916
The Sykes–Picot line

16 May 1916 — The same year as the promises to Hussein, Britain and France secretly rule lines across the post-Ottoman Middle East: “A” for France, “B” for Britain. The Bolsheviks publish the map in 1917. The double promise shapes a century.
THE MOMENT IN CONTEXT
Call it the First World War and mean it: look at how little of this map is parchment. Around four million men from Africa, Asia, the Pacific and the Americas served the European empires — 1.4 million from British India alone, fighting from Flanders to the Tigris; some 450,000 tirailleurs and other troops from French Africa; 140,000 laborers of the Chinese Labour Corps digging the Western Front (marked at Weihaiwei, where they embarked); porters in Africa by the million, conscripted at gunpoint, who died of disease and overwork in numbers — perhaps 100,000 in East Africa alone — that no one troubled to count precisely. The Dominions sent armies that came home nations: Canada took Vimy, Australia and New Zealand counted Gallipoli as a founding, South Africa took German South-West Africa while suppressing a Boer revolt at home. None of these peoples chose the quarrel in Sarajevo. All of them paid for it — and many concluded, watching their rulers bleed, that the empires were neither invincible nor grateful.
From Chapter 7 — The World’s War of The Great War, 1914–1918 (MAY 1917).
