Carucage was a medieval English land tax enacted by King Richard I in 1194, based on the size—variously calculated—of the taxpayer's estate. It was a replacement for the danegeld, last imposed in 1162, which had become difficult to collect because of an increasing number of exemptions. Carucage was levied just six times: by Richard in 1194 and 1198; John, his brother and successor, in 1200; and John's son, Henry III, in 1217, 1220, and 1224, after which it was replaced by taxes on income and personal property.
