Defeated and killed Cadwallon of Gwynedd in 986 and assumed control of that kingdom. In 987 he took over the government of Deheubarth from his aged father. His son Cadwallon died in 992, and his daughter Angharad married Llywelyn ap Seisyll. Maredudd died in 999. The Brut, often extravagant in its praise, called him ‘the most famous king of the Britons’, and he appears to have dealt strongly with both Viking raids and Saxon incursions.
