Modern pizza, as we know it today, originated in Italy as the Neapolitan pie with tomato and the cheese was added in 1889. The pizza is from Italy, but was not developed until after the cultivation of the tomato, brought back to Spain from Central America in the 1500's.
The history of pizza has been, and is contentious, for we can never know which nation invented pizza, but pizza history is no less colorful for that fact. As we cannot know the date when the first pizza was invented ,we can only speculate who invented pizza. Mozzarella is made from buffalo's milk and had never before been used to make a pizza. 2  Ironically a cheese, basil and tomato pizza was already popular in Naples, but it did not have quite the same impact in the annals of pizza history.
