Brigantia is the land inhabited by the Brigantes,[1][2][3] a British Celtic tribe which occupied the largest territory in ancient Britain. The territory of Brigantia which now forms Northern England and part of The Midlands covered the majority of the land between the River Tyne and the Humber estuary forming the largest Brythonic Kingdom in ancient Britain.[4] It was recorded by Ptolemy in the 2nd century AD to extend sea to sea, from the Irish Sea on the west coast to the North Sea in the east.
