Did Russia drop out of world war 1 after it was conquered and occupied by Germany?

No, Russia did not drop out of World War I because it was conquered and occupied by Germany. Instead, Russia exited the war following the Bolshevik Revolution in 1917, which led to the signing of the Treaty of Brest-Litovsk in March 1918. This treaty formalized Russia's withdrawal from the conflict, allowing Germany to focus its efforts on the Western Front. The country's withdrawal was primarily due to internal political upheaval rather than outright military conquest by Germany.
