 Together with the Tribe of Ephraim, Manasseh also formed the "House of Joseph".In the biblical chronicle, the Tribe of Manasseh was a part of a loose confederation of Israelite tribes from after the conquest of the land by Joshua until the formation of the first Kingdom of Israel in c. 1050 BC.No central government existed, and in times of crisis the people were led by ad hoc leaders known as Judges (see Book of Judges).
