What nationality was St. Patrick?
He was born in Roman Britain, probably Scotland, of parents who were Roman citizens.
It is thought that Patrick's original name was Maelwyn Succat and he was a British Celt possibly born in Wales around 387. Britain was a Roman colony until around 409 AD when the last legions left. That would have made him a Roman citizen.The Celtic Britons had adopted many aspects of Roman culture and were referred to as 'Romanized Britons'. In today's terms he would be a Welshman.
