Coritani

A British tribe and civitas. It occupied the territory between the rivers Welland and Humber, fringed on the west by the southern Pennines. The impression of the tribe at the time of the Roman conquest is that it was not yet united into a single powerful kingdom. This may explain the rapid Roman advance through their territory, culminating in the foundation of a legionary fortress at Lincoln ADc.60. The pacified tribe were awarded local self-government as a civitas a decade or two later, with Leicester, known as Ratae Coritanorum, as its administrative centre.
