Answer:
Its location on seven hills
Explanation:
The location of the city of Rome was especially favorable to its early settlers. Located about 18 miles (29 km) inland on the Tiber River, Rome had a route to the sea. However, it was far enough inland to be relatively safe from pirates. It could be easily defended because of its position, built on seven hills. In addition, it was situated where the Tiber River could be easily crossed. Thus, it became a natural crossing point for north-south traffic in western Italy. All in all, Rome had a good central location in Italy from which to expand.
