The crisis in most cities in the 4th and 5th centuries contrasted sharply with the growth of Barcino. Rural regions tended towards self-organisation and Barcino was perfectly located for structuring a wealthy regional framework. Excellent natural communications with the hinterland increased the city's status as a new centre. During the 4th and 5th centuries, Barcino was heavily fortified and became a political focal point and a centre of conspiracies and uprisings. Maximus the Tyrant, the self-proclaimed emperor, grew powerful in the city. Ataulph and Galla Placidia made it the capital of the Visigothic kingdom.
