What was a key similarity between the Russian Revolutions of 1917 and the Chinese Revolution of 1945-1949?

The Russian Revolutions of 1917 and the Chinese Revolution that took place from 1945 to 1949 share the key similarity of being influenced by the devastating impact of war on their respective countries. In Russia, the First World War and the subsequent civil conflict created widespread chaos, discontent, and a desperate desire for change among the populace, leading to the Bolshevik Revolution. Similarly, China experienced immense upheaval due to the Second Sino-Japanese War and the subsequent civil war between the Nationalists and Communists. The toll of these conflicts highlighted societal issues and fostered revolutionary sentiments, ultimately paving the way for the establishment of Communist rule in China.

This connection underscores the role of conflict as a catalyst for revolutionary movements, as both nations faced significant challenges that contributed to their revolutionary paths. In contrast, other options do not capture this shared impetus as directly. While issues like industrialization and agrarian reforms played roles in each society's transformation, the primary driving force behind the revolutions in both cases was the profound impact of war and the resultant social and political instability.
