How were the social classes divided during WW 1 and up to the Russian revolution?

During World War I and leading up to the Russian Revolution, Russian society was primarily divided into three main social classes: the nobility, the middle class (including merchants and professionals), and the peasantry. The nobility held significant wealth and political power, while the middle class was emerging but still relatively small and often marginalized. The vast majority of the population were peasants, who faced harsh living conditions and had limited rights, leading to widespread discontent. This social stratification contributed to the revolutionary sentiments that ultimately culminated in the 1917 Revolution.
