Explanation:

    In the 3rd and 2nd centuries a. C., the Romans clashed with Carthage (located in the north of Africa), that until then dominated a vast commercial empire in the Central and Western Mediterranean. After violent and prolonged military battles, known as Punic wars (Punic derives from puni, which means Phoenician - which as the Romans called the Carthaginians), the Carthaginians were defeated and the Romans seized North Africa, Sicily and the Mediterranean coasts of Iberian Peninsula.

    After eliminating their rival Carthage, the Romans conquered the Iberian Peninsula, Gaul, the territories on the right bank of the Danube River, Egypt. They also took Britain, Dacia (Romania), Macedonia and several territories in Asia Minor.

Both allowed for the easier movement of troops.
