Gaius Flaminius was a Roman consul most known for being defeated by Hannibal at the Battle of Lake Trasimene during the second Punic war. Hannibal was able to make pivotal decisions during this battle because he understood his opponent. Flaminius was described as a demagogue by Polybius, in his book the Rise of the Roman Empire. "...Flaminius possessed a rare talent for the arts of demagogy..." Because Flaminius was thus ill-suited, he lost 15,000 Roman lives, his own included, in the battle.
