What was to be accomplished in the first Punic war?

Answer 1

Control over Sicily. This island was of great strategic value because it controlled the routes between the western and eastern basins of the Mediterranean and economic value because it had good agricultural land. This would give Rome, the instigator of the war, a great advantage over Carthage, the other great power of the western Mediterranean, which had naval bases and settlements in the western area of the Island.

Besides the advantage of holding Sicily, which before the First Punic War, was dominated by Greeks and Carthage, the peace treaty abolished the "rule" that Rome was never to have trading or war ships west of that island. Unable to carry on the war which began in 264 BC and ended in 241 BC. By our standards this war was a long drawn out military affair lasting almost 23 years.

The accomplishment, as stated in the first sentence of this answer, also brought on other important results. Rome realized the importance of having a powerful navy. As Carthage was unable to support its troops in Corsica and Sardinia, these were annexed by Rome. The war left Rome as the supreme naval power in the western Mediterranean. With Carthage defeated, Rome could now focus on driving out foreign tribes that were in Northern Italy. To top things off, the treaty between Rome and Carthage required that Carthage pay an annual indemnity of 440 talents for the next ten years to Rome.
