Europe 1920: Treaty of Sevres

Ottoman Turkey was the last of the Central Powers to sign a treaty with the victorious Allies, surrendering much of its Middle Eastern empire to the British, French, Greeks, and Armenians. However in reality the Treaty was essentially worthless as it was the Nationalists, not the Ottomans, who now ruled Turkey.

12-25 Aug 1920 Battle of Warsaw

By June 1920, the Polish advance into Belarus and Ukraine was halted, and the Soviet Army began pushing back into what had been Polish territory before the outbreak of the war. British Foreign Secretary George Curzon petitioned the Soviets to ceasefire at what became known as the Curzon Line, but the Soviets refused and reached the Vistula by August. However, Polish forces intercepted and cut off the Soviets outside of the capital Warsaw, leading to massive Soviet casualties and a frantic, disorganized retreat.in wikipedia
