Barshchina is the labour, mostly agricultural, performed by a Russian peasant or serf for a landlord, whether the church, the state, or an individual landowner. Barshchina originated in Kievan Rus and became widespread in the later part of the Mongol Yoke, when agricultural production increased. The labour was performed one day weekly in the fifteenth century, and increased to three days in the seventeenth century. In 1797, it was forbidden to work on Sundays. Both men and women performed the labour, and children began limited services at age fourteen. Barshchina often included: sowing, reaping and bringing in crops; constructing buildings and fences and keeping them in repair; hunting and fishing; spinning flax; brewing beer; baking bread; working in flour and weaving mills; making bricks; and carting goods to market. Barshchina did not end in 1861, as freed peasants had to meet their obligations to former landlords for two years or until they had redeemed their land from the landlord.
