Until 428, Theodosius’ sister Pulcheria played an important role in the government. She was supplanted in importance by the emperor’s wife Eudocia, whose influence lasted until 441. Subsequently, the eunuch Chrysaphius enjoyed considerable power. Under Theodosius a system of impregnable walls was constructed around Constantinople (413), and an early Byzantine law code—the Codex Theodosianus—was promulgated (438). In 431 and 449 the emperor convoked ecumenical councils at Ephesus. Theodosius’ reign saw the loss of much territory in North Africa to the Vandals.
