A tribute (from Latin tribulum, contribution) is wealth one party gives to another as a sign of respect or, as was often case in historical contexts, of submission or allegiance. It also incorporate certain aspects of regulated trade in goods and services between the parties under a contractual relationship formed upon duress, and based upon the potential for threats if specific performance did not occur. A tributary or tributary state is a state, colony, region, or people who pay tribute to a more powerful, suzerain state.
