The Carthaginians were not Jewish. They were an ancient civilization that established the city of Carthage, which was located in modern-day Tunisia. Carthage was a major power in the Mediterranean region, known for its trade, military prowess, and as the opponent of Rome during the Punic Wars.
Carthage was originally founded by Phoenician settlers from the city of Tyre, and the populace practiced a polytheistic religion that included the worship of multiple gods, such as Baal and Tanit. The Phoenicians, including the Carthaginians, were known for their maritime trading and cultural influences throughout the Mediterranean.
Judaism, on the other hand, is the monotheistic religion of the Jewish people, with its own distinct cultural and religious practices. While there was contact between Jewish communities and the Phoenicians and Carthaginians throughout history, particularly as trade routes connected various cultures, the Carthaginians themselves did not adopt Judaism or identify as Jewish.
In summary, while there may have been interactions between Carthaginians and Jewish communities, the Carthaginian civilization was fundamentally different in its religious beliefs and cultural identity.
