Carthage was their head-quarters, and they were continually ravaging the coasts of the Mediterranean with their fleets.
Maximus, Emperor of Rome (455), had forcibly married Eudoxia, the widow of the previous Emperor, Valentinian, whom he had killed.

She in revenge sent to Genseric a secret message to attack Rome.

He at once set sail for the mouth of the Tiber.

The capital was delivered into his hands on his promise to spare the property of the Church (June, 455), and for fourteen days the Vandals ravaged it at pleasure.

Genseric then left Rome, taking with him Eudoxia.
This was the last sack of the city by barbarians.
