Birth of the European Feudal Hierarchy
Although the process is obscure, the result is quite clear. By 987 [C.E.] the soldiers of the West Frankish state were arranged in a feudal hierarchy bound together by oaths of vassalage. The king was at the top of the feudal pyramid: the suzerain of the land. A few dukes and counts were his direct vassals. They in turn had their vassals, rear vassals, and rear rear vassals. At the bottom of the pyramid was the simple knight with just enough land and peasant labor to support him, his family, and his horses. Now this structure was not all embracing by 987; in fact, it never was. As late as the latter part of the twelfth century the count of Dreux surrendered large allodial holdings to the count of Champagne and received them back as fiefs. A recent study has shown that large allodial estates persisted throughout the Middle Ages in the region around Bordeaux. But in comparison with the total area of the country these exceptions were of slight importance, and the principle beloved by feudal lawyers—no land without a lord—became essentially true. Thus all land was someone’s fief and every landholder except the king was someone’s vassal. The soldiers, the knights, held the land of France, and they were bound together by the feudal system.
