The Origins and History of Pizza

Modern pizza evolved from flatbread dishes in Naples during the 18th or early 19th century. In its earliest forms, these flatbreads were topped with basic ingredients such as salt, lard, garlic, and cheese. The introduction of tomatoes—a key component of the modern version—occurred after the 16th century following the Columbian Exchange, which brought New World crops to Europe.

Until approximately 1830, pizza was primarily a street food sold from open-air stands and bakeries. This changed when Neapolitan pizzerias began introducing stanze (rooms) with tables, allowing customers to dine in.

The Rise of the Modern Pizza

Raffaele Esposito is widely credited with creating the modern version of pizza in Naples toward the end of the 19th century. One of the most famous iterations is the Pizza Margherita. According to popular legend, its ingredients—red tomatoes, white mozzarella, and green basil—were chosen to mirror the colors of the Italian national flag.

The ingredients of traditional pizza Margherita—tomatoes (red), mozzarella (white), and basil (green)—are held by popular legend to be inspired by the colors of the national flag of Italy.[57]

Global Expansion

Pizza reached the United Kingdom after World War II via Italian immigrants. However, it gained widespread popularity in 1965 when entrepreneur Peter Boizot opened PizzaExpress in London after experiencing authentic Neapolitan pizza in 1948. This chain eventually expanded to over 500 outlets across the UK and Ireland.

Preserving Tradition: Neapolitan Pizza

To protect the authenticity of the craft, the Associazione Verace Pizza Napoletana (True Neapolitan Pizza Association) was founded in 1984. Their efforts have led to significant official recognitions:

2009: Registered with the European Union as a Traditional Speciality Guaranteed (TSG) dish.
2017: Included on UNESCO's list of intangible cultural heritage.

Regional Varieties and Styles

As pizza spread, it adapted to local tastes, resulting in a vast array of styles. In the United States, the market is massive, with 76,000 pizzerias and a 2017 market value of $44 billion.
