Final answer:
Carthage is located in modern-day Tunisia, and Rome engaged in three significant conflicts with this city-state, known as the Punic Wars, due to territorial and control disputes over the western Mediterranean and Sicily.
Step-by-step explanation:
Carthage is located in modern-day Tunisia, and Rome engaged in three major conflicts with this city-state, known as the Punic Wars. These wars were fought due to a combination of territorial ambition and the struggle for hegemony in the western Mediterranean, particularly over the control of Sicily. The Punic Wars stretched from 264 BCE until 146 BCE, with Rome ultimately emerging as the dominant power.
During the First Punic War (264-241 BCE), Rome and Carthage battled over Sicily, resulting in Rome annexing the island after Carthage sued for peace. The second conflict, known as the Second Punic War (218-202 BCE), was marked by the Carthaginian general Hannibal's famous crossing of the Alps and his initial successes in Italy. However, Rome recovered and eventually defeated Carthage. Fueled by a desire for complete dominance and Carthaginian resistance, the Third Punic War (149-146 BCE) ended with the total destruction of Carthage, and the city was eventually rebuilt as a Roman settlement.
