Explanation:

The Treaty of Versailles of 1919 was a peace treaty that officially marked the end of World War I (1914-1918). Signed between Germany and the Entente Powers (France, Britain, Italy, the United States and Japan), it nevertheless excluded Russia, which had been part of the allied powers fighting Germany until the Bolshevik government withdrew from the war. The Russian government and its population opposed the war, and the Treaty of Brest - Litovsk, a previous peace treaty, had been signed between Soviet Russia and Germany and its allies on March 1918. The conditions imposed upon Russia by this treaty were extremely onerous, as it had to cede large swathes of its Western territories to Germany as a requisite for peace. Although the Armistice of November 1918 and the Treaty of Versailles both annuled the Treaty of Brest-Litovsk, the Baltic nations and parts of Poland and Ukraine weren't returned to Russia, but became part of independent nations. This circumstance meant that effectively Russia lost territory under the terms of the Treaty of Versailles, which made the new Soviet Russia leaders deeply unhappy.
