Seaport (pop., 2004 est.: 410,700), northeastern Algeria. Identified with the port of ancient Hippo (or Hippo Regius), it was a rich city of Roman Africa. It was home to St. Augustine 396–430. Severely damaged by the Vandals in 431, it passed to the Byzantine Empire in 533 before being overrun by the Arabs in the 7th century and named Bona. It was occupied by the French in 1832 when they conquered Algeria. Modern Annaba is Algeria's chief exporter of minerals; it also serves as a trading port and port of call.
