Before the Punic Wars, relations between Rome and Carthage were very good and the two had strong commercial links.
The First Punic War was caused because the Mamertines, a group of mercenaries who controlled Messina, expelled the Carthaginian garrison of the city and replaced it with a Roman one; this angered the Carthaginians who allied with Syracuse and sieged Messina seeking revenge starting the war.
But what if the Carthaginians never accepted the Mamertines' help request and therefore didn't have any garrisons in the city?
Would Rome still conquer parts of Sicily? If yes how and when?
How would Rome's expansion continue?
Would the Barca still gain enough relevance to expand Carthage's territories in Iberia?
