The Treaty of Brest-Litovsk, signed on 3 March 1918, outlined the harsh conditions under which the crumbling Russian Empire withdrew from the First World War (1914-18). Negotiated by Vladimir Lenin (1870-1924), the leader of Soviet Russia after the Russian Revolution of 1917, and the German Kaiser Wilhelm II (reign 1888-1918) and his Central Powers allies, the treaty stripped away most of the non-Russian territories that the tsars had conquered in the previous 200 years.
