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.
This system helped the rulers of the Middle Ages bring order to the nations, as a lord granted fiefs (land) to those who vowed to give military protection to him. Feudalism started around A.D. 700 and was probably at its strongest in the 900's up to the 1200's. It served its purpose and was gone by the 15th century.
