Prehistoric Ireland

The Brigantes were a tribe or confederation of Celtic Britons who dwelt in what is now Northern England during the Iron Age and Roman era. Their territory, often referred to as Brigantia, was probably the largest of the British tribes and was centred on the Pennines and what is now Yorkshire. Their Roman-era capital was Isurium Brigantum (Aldborough), and the city of Eboracum (York) was within their territory. They are also associated with Stanwick fort. Prominent leaders named in Roman sources were queen Cartimandua and king Venutius.
