 In 1029, John, but not Sergius, returned and reasserted his authority, deposing his mother and brother.In 1031, John named his son Sergius III co-regent and successor and he received the title of "patrikios" from the Byzantine emperor, as his father had in 1010.In April or May 1034, John was forced to flee Amalfi again, this time because Pandulf had conquered Gaeta (1032) and was threatening the remaining coastal cities, including Naples, to which John fled, for Duke Sergius IV of Naples was likewise sheltering the deposed John V of Gaeta.
