When the news of these proceedings reached the camp, the king, alarmed at the turn affairs were taking, hurried to Rome to quell the outbreak. Brutus, who was on the same road, had become aware of his approach, and to avoid meeting him took another route, so that he reached Ardea and Tarquin Rome almost at the same time, though by different ways.

Tarquin found the gates shut, and a decree of banishment passed against him; the Liberator of the City received a joyous welcome in the camp, and the king's sons were expelled from it. Two of them followed their father, into exile amongst the Etruscans in Caere. Sextus Tarquin proceeded to Gabii, which he looked upon as his kingdom, but was killed in revenge for the old feuds he had kindled by his rapine and murders.

Lucius Tarquinius Superbus reigned twenty-five years. The whole duration of the regal government from the foundation of the City to its liberation was two hundred and forty-four years. Two consuls were then elected in the assembly of centuries by the prefect of the City, in accordance with the regulations of Servius Tullius. They were Lucius Junius Brutus and Lucius Tarquinius Collatinus.
