What period did the Punic Wars span?

The Punic Wars spanned from 264 to 146 BC, making this the correct choice. This series of three wars between Rome and Carthage were pivotal in establishing Roman dominance in the Mediterranean.

The First Punic War began in 264 BC primarily over control of Sicily, and it continued for nearly 24 years, ending in 241 BC. The Second Punic War, famous for Hannibal's tactics, lasted from 218 to 201 BC. The Third Punic War culminated in the complete destruction of Carthage in 146 BC.

This period was significant not only for the territorial expansion of Rome but also for the military and political changes that shaped Rome's future as a dominant empire. The other choices do not accurately represent the timeframe of these major conflicts.
