The Catuvellauni ('men excelling in battle') were the most powerful tribe in late Iron Age Britain, and Addedomaros was one of their most powerful kings. He was the first ruler north of the Thames to include his name on his coinage, which suggests to some that he may have been literate in Latin and Greek.
