The Phoenicians founded many city-states. These city-states often competed against each other. Do you think it would have made more sense to cooperate?

Cooperation between Phonecian city-states was unlikely because of their geographical locations - they were scattered along the Mediterranean coasts. Though some Phonecian city-states may have cooperated especially in trading, their prosperous condition despite being independent from each other is why they didn't need to create a united front.
