Final answer:
Hannibal received limited support from regions conquered by Rome, as most of the Italian allies stayed loyal to Rome despite Hannibal's victories. His inability to gain widespread support among these regions contributed to the failure of his campaign, eventually leading to defeat at the Battle of Zama in 202 BCE.
Step-by-step explanation:
During the Second Punic War, Hannibal did indeed receive some support from the people that Rome had conquered. However, most of Rome's Italian allies remained loyal even after Hannibal repeatedly defeated Roman armies. His strategic maneuvers, including his infamous trek with war elephants across the Alps and his victories in major battles like Cannae, were not enough to convincingly sway Rome's subjected peoples to his side. The Carthaginian general faced difficulties winning over the southern Italian peoples, which significantly hampered his campaign.
Hannibal's initial successes and clever tactics led to some cities in Italy and Sicily starting to defect to the Carthaginian side, reflecting a degree of support from conquered people. Yet, the overall failure to garner widespread support weakened his position, and despite his battlefield prowess, he never managed to force Rome into submission. The Romans, adapting their military tactics and focusing on preventing Hannibal from receiving reinforcements, gradually weakened his forces. The war reached its conclusion at the Battle of Zama in 202 BCE, where the Roman forces under Scipio Africanus defeated Hannibal and Carthage sued for peace, leading to Rome securing Carthage's lands in Hispania.
