Battle of Allia

The Battle of Allia took place in 390 BCE near Rome when the invading Gauls, led by Brennus, overwhelmed the Roman army. Despite having a stronger force, the Romans were unprepared and poorly organized, leading to a decisive defeat. This loss allowed the Gauls to sack Rome, causing widespread destruction and panic. The battle is significant as it marked one of Rome’s early major military setbacks and highlighted the importance of discipline and strategy in warfare. Following the defeat, Rome took steps to strengthen its military and defenses to prevent future invasions.
