Ramses III, a pharaoh of the 20th dynasty, saved Egypt from foreign invasion but failed to solve internal problems--political conspiracies and weakened social structure--that led to the collapse of the Egyptian state 80 years after his death. Succeeding his father, Sethnakhte, in c.1198 BC, Ramses fought off Libyan invasions in 1194 and 1188. In 1191 he also held back a horde of invading Sea Peoples of Aegean and west Anatolian origins who had been sweeping down the eastern Mediterranean coast toward Egypt. Despite external successes, royal power declined. The temples became richer and Ramses poorer; he attempted building only one major structure. Government was corrupt and inefficient, and Ramses himself was nearly assassinated before being succeeded by his son Ramses IV about 1166 BC. He was buried in the Valley of the Kings.
