Final answer:
The Bolshevik Revolution led to the Treaty of Brest-Litovsk in 1918, which benefited Germany by giving them significant territorial gains from Russia. This helped the Germans by providing them with new ports and resources, and allowed them to focus their military forces on the western front.
Step-by-step explanation:
The Bolshevik Revolution, led by Vladimir Lenin, resulted in the signing of the Treaty of Brest-Litovsk in 1918. This treaty allowed Germany and the Central powers to gain significant territory from Russia, including areas of Poland, Ukraine, Finland, and the Baltic states. By giving up these territories, Russia was able to end its participation in World War I and focus on building a Communist state, the Soviet Union.
The Treaty of Brest-Litovsk helped the Germans in 1918 by providing them with new ports and resources from the acquired territories. It also allowed Germany to shift its military forces from the eastern front to the western front, where they launched a major offensive against the Allied forces. Although Germany ultimately lost the war, the treaty temporarily provided them with advantages and strengthened their position in 1918.
