Pizza originates in Ancient Greece where flat breads were topped with vegetables. It was served in Italy as just flat breat with nothing on top and called Pita.
It wasn't until the 18th century that pizza was taken on commercially in Italy.
Queen Margherita saw peasants eating the flat breads in 1889 and got her chef to prepare it for her and the toppings were in the colours of the Italian flag (red, white and green) using tomatoes, mozzerella cheese and basil.
The Marghertita pizza is the most popular in Italy and Naples is most famous for it.
In WW1 American soldiers in Italy discovered pizza and by WW2 it was spreading worldwide.
There are over 5 billion pizzas sold per year worldwide.
The most popular pizza has a thin crust.
You will never find ham and pineapple pizza in Italy as it is not considered a propper pizza topping.
