Corvée- The term is most typically used
in reference to Medieval or early modern Europe, where work might be demanded
by a feudal lord of his vassal or by a monarch of his subject; however the
application of the term is not strictly limited to that time or place: the
practice is widespread, of great antiquity, and not extinct. Corvée has existed
in modern and ancient Egypt, ancient Rome, China and Japan, everywhere in
continental Europe, and Incan civilization. The corvée differs from forced
labor in that the work obligation was intermittent and for a limited period of
time: typically only a certain number of days' work each year. Unlike other
forms of levy, such as a tithe, the corvée does not require the population to
have land, crops or cash and thus it tends to be favored in economies where
money is in short supply.
