Long ago, two big groups fought for power. 
A leader named Hannibal led the Carthage army. He marched his men over high mountains. This was a big surprise for Rome. Hannibal won many battles in Italy. 
Rome had to find more men to fight. They even asked people who were not soldiers to help. This helped Rome stay in the fight.
Later, a Roman leader named Scipio went to Africa. He fought Hannibal one last time. Rome won the war in the end.
After the war, Carthage had to follow Rome's rules. It was a very big change for them.
Long ago, two great powers fought for control. 
A leader named Hannibal led the Carthaginian army. He surprised Rome by marching his men over the Alps. These are very high mountains. Hannibal won many big battles in Italy. One famous win was at Cannae. This was a very large battle.
Rome had to find more men to fight. They even asked slaves and criminals to join. This helped Rome grow its army. 
Later, a Roman leader named Scipio took the fight to Africa. He fought Hannibal one last time at Zama. Scipio won the battle.
Carthage lost the war. They had to pay Rome a lot of money. They also lost their lands far from home. Rome became the main power in the area. 
The Second Punic War was a huge struggle for power. It lasted for 17 years from 218 to 201 BC. 

War in this time involved many different types of soldiers. 

A famous leader named Hannibal led the Carthaginian side. 
Rome had to work hard to keep fighting. 
The war ended after a final battle at Zama in 202 BC. 
The Second Punic War was a massive conflict between 218 and 201 BC. 

To understand the war, one must look at how the armies were built. Roman armies were organized into large units called legions. Each legion usually consisted of 4,200 infantry and 300 cavalry. Most Roman soldiers were heavy infantry. They carried large shields, body armor, and short thrusting swords. Some men served as light skirmishers called velites. They used javelins to attack from a distance. Rome's leaders were called consuls. Two consuls were elected every year to lead the armies.
The Carthaginian military functioned very differently. While Carthaginian citizens fought as heavy infantry, the army relied heavily on foreigners. Many soldiers came from North Africa and were called Libyans. These troops included heavy infantry and light cavalry. The Numidians were famous for providing light cavalry skirmishers. Carthage also used war elephants in battle. 
The war began after Carthage captured the pro-Roman city of Saguntum in 219 BC. In 218 BC, Rome declared war. The Carthaginian general Hannibal Barca launched a famous surprise attack. He marched his army from Iberia through Gaul and over the Alps. This difficult journey brought his forces into northern Italy. Hannibal won major victories at the battles of Trebia and Lake Trasimene. In 216 BC, he won a massive victory at Cannae. At Cannae, Hannibal destroyed the largest army Rome had ever assembled. 
Rome responded to these losses with drastic measures. To increase their numbers, they enrolled slaves and criminals into the legions. This allowed Rome to keep fighting despite losing over 120,000 troops in three years. While Hannibal stayed in southern Italy, the war spread elsewhere. Macedonia and Syracuse joined the Carthaginian side. However, the Romans began to win back control of Italian cities. In Iberia, the Roman commander Publius Scipio changed the course of the war. In 209 BC, he captured the main Carthaginian base, Carthago Nova. 
Scipio eventually took the fight directly to North Africa in 204 BC. This move forced the Carthaginian Senate to recall Hannibal from Italy. The final major battle occurred at Zama in 202 BC. At Zama, Scipio defeated Hannibal. This led to a peace treaty that heavily favored Rome. Carthage had to pay an indemnity of 10,000 silver talents over 50 years. They also lost their overseas territories. Carthage was no longer allowed to wage war without Rome's permission. This made Carthage politically subordinate to Rome.
Much of what we know comes from ancient historians. Polybius is considered the most reliable source for this war.
