In 387 BC, Rome was sacked and burned by the Senones coming from eastern Italy and led by Brennus, who had successfully defeated the Roman army at the Battle of the Allia in Etruria. Multiple contemporary records suggest that the Senones hoped to punish Rome for violating its diplomatic neutrality in Etruria. The Senones marched to Rome without harming the surrounding countryside; once sacked, the Senones withdrew from Rome. Brennus was defeated by the dictator Furius Camillus at Tusculum soon afterwards.
