In the Medieval years, the name "France" ( Latin "Francia" ) was derived from tribes called the Franks Feudalism flourished in medieval Europe in the 9th to 15th century. A system of legal, military and social customs defining the relationship of holding land in lieu of services or labor. Feudalism was the result of the decentralization of the Carolingian Empire. As a result, soldiers secured a system to rule over their lands with powers encompassing the judicial, political, economic and social domains When the Roman Empire collapsed, France was entirely unlinked from the European economy. There was a great decline in trade and manors became more self-sufficient than progressive. During the 13th century, catastrophes and famines plagued the French people The tribes of France during the early medieval period were not very organized. Most of these men were hunters and trappers. Feudalism was used by the Normans in France from the time they first settled in the region and it was a simple and effective system of control. All the lands were owned by the King and some were given to the church while the rest were leased out to Barons and Lords under strict agreement that they will provide services to the king in exchange to the lands leased out to them. A quarter of the land was kept by the King as his personal property and he has complete control over the system Reference: http://www.medievalchronicles.com/medieval-europe/medieval-france/
