The social causes of the Russian Revolution can be derived from centuries of oppression of the lower classes by the Tsarist regime and Nicholas's failures in World War I. While rural agrarian peasants had been emancipated from serfdom in 1861, they still resented paying redemption payments to the state, and demanded communal tender of the land they worked. The problem was further compounded by the failure of Sergei Witte's land reforms of the early 20th century. Increasing peasant disturbances and sometimes actual revolts occurred, with the goal of securing ownership of the land they worked. Russia consisted mainly of poor farming peasants and substantial inequality of land ownership, with 1.5% of the population owning 25% of the land.

The rapid industrialization of Russia also resulted in urban overcrowding and poor conditions for urban industrial workers (as mentioned above). Between 1890 and 1910, the population of the capital, Saint Petersburg, swelled from 1,033,600 to 1,905,600, with Moscow experiencing similar growth. This created a new 'proletariat' which, due to being crowded together in the cities, was much more likely to protest and go on strike than the peasantry had been in previous times. In one 1904 survey, it was found that an average of 16 people shared each apartment in Saint Petersburg, with six people per room. There was also no running water, and piles of human waste were a threat to the health of the workers. The poor conditions only aggravated the situation, with the number of strikes and incidents of public disorder rapidly increasing in the years shortly before World War I. Because of late industrialization, Russia's workers were highly concentrated. By 1914, 40% of Russian workers were employed in factories of 1,000+ workers (32% in 1901). 42% worked in 100–1,000 worker enterprises, 18% in 1–100 worker businesses (in the US, 1914, the figures were 18, 47 and 35 respectively).
