Why is Pizza so popular in Naples?

Why is Pizza so popular in Naples then you ask? This is so for the same reason that Italy has only one unifying Italian language, yet hundreds of different spoken dialects. Italy is a country of great variety, and cooking is just another aspect of the diversity of Italian culture.This diversity stems largely from peasant heritage and geographical differences. Italy is a peninsula separated from the rest of the continent by the highest chain of mountains in Europe. In addition, a long spine of mountains runs north to south down through this narrow country. These geographic features create a myriad of environments with noticeable variations: fertile valleys, mountains covered with forests, cool foothills, naked rocks, Mediterranean coastlines, and arid plains. A great variety of different climates have also created innumerable unique geographical and historical areas.But geographical fragmentation alone will not explain how the same country produced all of these: the rich, fat, baroque food of Bologna, based on butter, parmigiano, and meat; the light, tasty, spicy cooking of Naples, mainly based on olive oil, mozzarella, and seafood; the cuisine of Rome, rich in produce from the surrounding countryside; and the food of Sicily, full of North African influences.
