Corvée () is a form of unpaid forced labour that is intermittent in nature, lasting for limited periods of time, typically only a certain number of days' work each year. Statute labour is a corvée imposed by a state for the purposes of public works. As such it represents a form of levy (taxation). Unlike other forms of levy, such as a tithe, a corvée does not require the population to have land, crops or cash.
