The Prussian Reform Movement was a series of constitutional, administrative, social, and economic reforms early in 19th-century Prussia. They are sometimes known as the Stein–Hardenberg Reforms, for Karl Freiherr vom Stein and Karl August von Hardenberg, their main initiators. German historians, such as Heinrich von Treitschke, saw the reforms as the first steps towards the unification of Germany and the foundation of the German Empire before the First World War.

Serfdom was the status of many peasants under feudalism, specifically relating to manorialism, and similar systems. It was a condition of debt bondage and indentured servitude with similarities to and differences from slavery. It developed during late antiquity and the Early Middle Ages in Europe and lasted in some countries until the mid-19th century.
