Wigan was in the territory of the Brigantes, an ancient Celtic tribe that ruled much of what is now northern England. The Brigantes were subjugated in the Roman conquest of Britain and the Roman settlement of Coccium established where Wigan lies.
Wigan was incorporated as a borough in 1246, following the issue of a charter by King Henry III of England. At the end of the Middle Ages, it was one of four boroughs in Lancashire established by Royal charter.
