Final answer:
The claim that Hannibal was made to swear an oath to help the Romans is false; he was sworn to enmity against Rome. The reconquering of the Iberian Peninsula by the Spanish was indeed a military and religious effort, known as the Reconquista, true in the provided True/False question.
Step-by-step explanation:
The statement "Barca made his son Hannibal take an oath to help the Romans when he grew up" is False. It is a well-known historical account that Hannibal's father, Hamilcar Barca, made young Hannibal swear an oath of enmity against Rome. This momentous event had a profound influence on Hannibal, who became one of Rome's greatest adversaries during the Second Punic War, leading his army against Rome in several decisive battles including Cannae.
Regarding the separate True/False question, it is True that for the Spanish, reconquering the Iberian Peninsula was both a military and religious action, a period known as the Reconquista. This era involved various Christian kingdoms in Iberia attempting to reclaim territory from Muslim rulers, combining efforts to expand their political power while also seeking to spread Christianity. The Reconquista was completed with the fall of Granada in 1492.
