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 feudal system was created, or rather evolved, to meet threats of invasion and other chaos that were more or less constant from the middle of the third century in the Romanâ¦ Empire and the states that occupied the lands of the Roman Empire after it divided and the West Roman Empire collapsed.
