Which of the following explains how the Russian Revolution affected Russia's involvement in the war?

The Russian Revolution had a significant impact on Russia's involvement in World War I. The correct answer would be option D - "It led to Russia's withdrawal from the war in 1917."

The Russian Revolution, which took place in 1917, resulted in the overthrow of the Russian monarchy and the establishment of a communist government under the leadership of Vladimir Lenin. This political transformation had direct consequences for Russia's participation in the war.

Firstly, the revolution caused significant instability and chaos within Russia. The country was experiencing widespread economic and social problems, and the military was facing internal dissent and low morale. These factors weakened the Russian army's ability to continue fighting effectively.

Secondly, the new Bolshevik government, led by Lenin, campaigned for "peace, land, and bread" for the Russian people. Their focus shifted towards consolidating power internally and addressing the needs of the war-weary population. As a result, the Bolsheviks were less interested in continuing the costly and unpopular war effort.

In March 1918, the Bolshevik government signed the Treaty of Brest-Litovsk with Germany, effectively ending Russia's participation in World War I. This treaty required Russia to give up significant amounts of territory and resources to Germany and its allies. The decision to withdraw from the war was driven by the desire to consolidate power domestically and eliminate the burden of the war effort on the struggling Russian economy.

Overall, the Russian Revolution led to Russia's withdrawal from the war in 1917, as the Bolshevik government focused on consolidating power internally and addressing the needs of the Russian population.
