Serfdom in Moldavia and Wallachia

Serfdom was widespread in Moldavia and Wallachia between 15th and 18th centuries, replacing the obște (autonomous communities) which were common before the founding of the medieval states of Wallachia and Moldavia. Initially, the serfs were allowed to change the estate on which they lived (sometimes in exchange for a sum of money paid to the boyar), although restrictions were introduced over the decades.
