A long mountain-backed peninsula projecting deep into the central Mediterranean. The Apennines create narrow coastal corridors while the Tyrrhenian and Adriatic shores open to major sea routes. Volcanic soils, enclosed plains, and accessible harbors made this one of the most self-contained and expansion-capable regions of the ancient world. Its geography funnels power toward central nodes (Rome, Naples, Palermo) and gives it maritime reach in every direction.
