.The recorded history of Manchester began with the civilian settlement associated with the Roman fort of Mamucium, which was established in c. 79 CE on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically, Manchester was in Lancashire, although areas of Cheshire, south of the River Mersey were incorporated into the city during the 20th century. Throughout the Middle Ages Manchester remained a manorial township but began to expand "at an astonishing rate" around the turn of the 19th century. - Source: Wikipedia
