Abolition of serfdom in Poland
Abolition of serfdom in Poland was a gradual process tied to the economy of the Polish–Lithuanian Commonwealth, where the nobility depended on serf labour for income and status. Initial steps toward reform began in the late 18th century, with the Constitution of 3 May 1791 offering limited protections to peasants and the Połaniec Proclamation of 1794 reducing some obligations of serfs and granting limited rights, such as personal freedom and protection from landlord abuses, during the Kościuszko Uprising.
