When Catherine II came to power in 1762, the city's filth and the smell of sewage were depicted by observers as a symptom of disorderly lifestyles of lower-class Russians recently arrived from the farms. Elites called for improving sanitation, which became part of Catherine's plans for increasing control over social life. National political and military successes from 1812 through 1855 calmed the critics and validated efforts to produce a more enlightened and stable society. There was less talk about the smell and the poor conditions of public health. However, in the wake of Russia's failures in the Crimean War in 1855–56, confidence in the ability of the state to maintain order in the slums eroded, and demands for improved public health put filth back on the agenda.
