The features to be noticed are the relation of the vassal to his lord, the position of the king, and the economic organization of the land and the obligations of the cultivators to the landlords. The origin and growth of these features in the earlier age have been shown in nos. 180-208; it only remains to show how they were organized in the feudal age. The vassal was bound to the lord of whom he held a benefice or fief by the oath of fidelity and homage. He also owed his lord certain services of noble character, the chief of which was military service. This was not perpetual service, but was limited by law or custom, usually consisting of 40 days' active service, and a certain amount of guard in the castle of the lord or in the castle which the vassal held as a fief of the lord. Aids or money payments were also paid by vassals on certain occasions, such as the marriage of the lord's oldest daughter, the knighting of the lord's oldest son, and the captivity of the lord. The lord had also certain rights over his vassals, which were frequently commuted for money: wardship, the right of guardianship of minor heirs, and the management and use of the fiefs during the minority; marriage, the right to choose or be consulted in the choice of a husband for female holders of fiefs; relief, the right to exact a certain payment from the heir when he succeeded to a fief; escheat, the right of taking back the fief into his own possession upon the failure of heirs, etc. These rights and payments have their origin in the personal dependence of the vassal upon the lord. They were occasional and did not form a part of the regular income of the lord, although they might be worth considerable at times. The regular income of the lord came from his domain lands, the lands which were not let out in fief, but which were cultivated by tenants or serfs, and which supplied the lord with money, resources, and services. The authority of the king in the feudal state was very limited. This was due chiefly to the fact that each lord exercised practically sovereign rights over his lands and dependents. The feudal king was in origin one of the great feudal lords (cf. in France, Hugh Capet, duke of Francia; and in Germany, Henry I, duke of Saxony), who was chosen by the great lords and became their overlord. He had the same rights on his own domains as any feudal lord, but had only the authority of an overlord over his great vassals. He had no direct control over the vassal of his vassal, but could reach such an one only indirectly through that person's immediate superior. The holders of great domains exercised not only jurisdiction over the tenants on their lands, but possessed also other sovereign rights, such as the right of coinage, of collecting tolls and taxes, etc.
