Hannibal Barca was born into one of the most powerful families in Carthage. His father Hamilcar Barca was a leading general who had fought Rome in the First Punic War and harbored deep hatred for the Roman Republic.

Before accompanying his father to Iberia, young Hannibal was made to swear an oath at the altar of Ba'al to never be a friend of Rome. This oath would define his entire life and military career.

Hamilcar Barca died fighting Iberian tribes, leaving the Carthaginian army under command of his son-in-law Hasdrubal the Fair. Hannibal continued to serve and learn military strategy under his brother-in-law.

After Hasdrubal's assassination, the Carthaginian army proclaimed Hannibal as their commander. At just 26, he took control of Carthage's most powerful military force and began planning his campaign against Rome.

Hannibal besieged and captured Saguntum, a city allied with Rome. This eight-month siege directly provoked Rome and led to the declaration of the Second Punic War, exactly as Hannibal had intended.

In one of history's most audacious military maneuvers, Hannibal led an army of 50,000 soldiers, 9,000 cavalry, and 37 war elephants across the treacherous Alps into Italy. The crossing took 15 days and cost nearly half his forces.

In his first major battle in Italy, Hannibal crushed a Roman army at Trebia using a brilliant ambush strategy. His concealed cavalry destroyed the Roman flanks while his infantry held the center, killing or capturing 30,000 Romans.

Hannibal executed the largest ambush in military history at Lake Trasimene. By concealing his entire army along the foggy shoreline, he trapped and annihilated a Roman army of 25,000 men, including the consul Flaminius.

At Cannae, Hannibal achieved perhaps the greatest tactical victory in ancient warfare. Using his famous double envelopment tactic, he encircled and destroyed a Roman army of 80,000 men, killing approximately 50,000-70,000 in a single day.

Hannibal forged an alliance with Philip V of Macedon against Rome, attempting to create a two-front war. However, Roman naval superiority prevented effective Macedonian intervention in Italy.

Hannibal marched his army to within three miles of Rome's walls in an attempt to draw Roman forces away from Capua. The Romans famously refused to panic, and the land where Hannibal camped was reportedly sold at full price.

Hannibal returned to Africa to face Scipio Africanus at Zama. In his only major defeat, Hannibal's army was destroyed by Roman tactics learned from studying his own methods. This battle ended the Second Punic War.

After the war, Hannibal entered politics and was elected suffete (chief magistrate) of Carthage. He reformed the city's corrupt government and finances, restoring its economic strength remarkably quickly.

When Rome demanded his surrender, Hannibal fled to the Seleucid court of Antiochus III. He would spend his remaining years as a wandering exile, offering military advice to Rome's enemies.

Hannibal served as military advisor to King Prusias I of Bithynia. He won a naval battle against Rome's ally Pergamon by catapulting pots of venomous snakes onto enemy ships—innovative warfare to the end.

When Roman agents finally cornered him in Bithynia, Hannibal took poison rather than fall into Roman hands. His last words reportedly were: 'Let us relieve the Romans from the anxiety they have so long experienced.'
