Champart

Champart was a tax in Medieval France levied by landowners on tenants. Paid as a share of the harvest, the amount due varied between $1/6$ and $1/12$, and typically $1/8$ of the cereal crop.

Regional names for champart included arrage, gerbage, parcière, tasque, and terrage.

Beginning in the early modern period, champart was converted into a cash rent, first in the Île-de-France region.
