The North is a region in Westeros that currently belongs to the Third Kingdom of the North (in the show), and was formerly (in the show) a constituent province of the Seven Kingdoms of Westeros. Prior to Aegon's conquest, the North comprised the territories of the First Kingdom of the North. Following the conquest, it became one of the seven main provinces of the Seven Kingdoms, and by far the largest. During the War of the Five Kings, the North seceeded from the Seven Kingdoms and became part of the Second Kingdom, until it effectively collapsed after the Red Wedding, with House Bolton taking over control of the North and bringing it back as a province. In the books, it is still a province under Bolton control. In the show, the Boltons were wiped out and the North has become a territory of the current Third Kingdom of the North.
