In medieval and early modern Europe, the term tenant-in-chief (or vassal-in-chief) denoted a person who held his lands under various forms of feudal land tenure directly from the king or territorial prince to whom he did homage, as opposed to holding them from another nobleman or senior member of the clergy. The tenure was one which denoted great honour, but also carried heavy responsibilities. The tenants-in-chief were originally responsible for providing knights and soldiers for the king's feudal army.
