Feudalism was a combination of legal and military customs in medieval Europe that flourished between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships derived from the holding of land in exchange for service or labour.
In the 19th century the adjective feudal evolved into a noun: feudalism. The term feudalism is recent, first appearing in French in 1823, Italian in 1827, English in 1839, and in German in the second half of the 19th century. The term feudal or feodal is derived from the medieval Latin word feodum.
