suzerain

“Even now, in the 21st century, some U.S. officials and elites still deep in their hearts know and understand the world through the framework of the suzerain and its colonies.”

The monarch was rapidly acquiring a centralized power, which was very different from the overlordship of a feudal suzerain.

The town was well fortified and garrisoned; the Counts of Foix and Comminges had come at the summons of their suzerain, and the citizens were earnest in defence.

It could be received only by the suzerain in person.

The English kings did, indeed, exercise some sort of suzerain authority over most of the neighbouring colonies, but this authority was probably never so complete as historians would have us believe.
