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.
The classical feudalism was based on a set of reciprocal legal and military obligations among the warriors of nobility. This system was the direct result of a need of security for the members of nobility, but for the serfs as well against the invasions and attacks by barbarians, pagans and Islamic invaders.
