The recorded history of Manchester began with the civilian settlement associated with the Roman fort of Mamucium. The Roman fort was established c. AD 79 near a crossing point on the River Medlock. The fort was sited on a sandstone bluff near the confluence of the rivers Medlock and Irwell in a naturally defensible position. It was erected as a series of fortifications established by Gnaeus Julius Agricola during his campaign against the Brigantes who were the Celtic tribe in control of most of northern England.
