So in that regard just be aware that serfdom is a really broad category that embodies the labor system that existed under fuedal societies. For example, one of the longest lasting systems of serfdom existed in the Russian Empire until the 1860s. The serfs of England revolted in the Elizabethan era and a system of tenant rent was implemented. So there are centuries long gaps in what serfdom was like depending on where you're looking. Material conditions for the 14th century peasant and the 19th century vary widely, but do have common structure and function.

Tolstoy and Dostoevsky wrote extensive literature of Russian serfdom, and worth a read. Although, well, its Tolstoy ans Dostoevsky. I have barely read either, for context.
