What sparked the Russian revolution

The Number of casualties caused by WWI

Explanation:

Yeet!

The Russian Revolution was sparked by the manner in which the people were treated and the miserable conditions in which they were living under the Tsar Nicholas II. The people were not willing to put up anymore with the poverty and unjustly treatment towards them, so led by Vladimir Lenin, they revolted. The revolution was successful at the end, and it put end to the monarchy in Russia, while it opened up the doors for the communism at the same time. Unfortunately for the Russians, the century ahead of them didn't turned out to be better, but the same, or even worse at times.
