Pizza is believed to have been invented in Naples

Pizza became more popular in Italy after it took off in the US

Pizza was invented in Naples, though it wasn't particularly popular outside the region. As it grew more popular elsewhere—and as more American and European tourists visiting Italy began asking for it—restaurants across Italy adopted the cuisine. It's something anthropologist Agehananda Bharati calls "the pizza effect."

A fresco from ancient Pompeii featured an 'ancestor of modern pizza'

A team of archaeologists discovered a fresco from 79 CE featuring what appears to be a proto-pizza: a pita topped with fruit, spices, and other toppings. One archaeologist in the PBS documentary below calls it an "ancestor of modern pizza in the sense that it's a very simple, poor kind of food."

One food history professor says pizza is more American than Italian

Legend has it that the Margherita pizza was named after an encounter with Queen Margherita

The Queen of Italy, Margherita of Savoy, visited Naples in 1889. As the story goes, chef Raffaele Esposito of Pizzeria Brandi made her a pizza with basil, mozzarella, and tomato, to represent the colors of the Italian flag, and eventually named the pie in her honor. Historians, however, note that the facts don't line up: The proof of her visit to the pizzeria is suspected to be a forgery created when the business was in dire straits in the 1930s.

After World War II, pizza took off in the US

Pizzerias opened in cities throughout the 1920s and '30s, especially those with large Italian immigrant populations, but the cuisine didn't take off nationally until after World War II. Some credit that with American soldiers' exposure to the food while stationed in Italy; others point to the invention of the mass-produced gas-fired ovens, which made opening a pizzeria considerably easier. Below is a 1944 clip from the New York Times, the first time the paper mentioned pizza.

Italian immigrants brought pizza to Argentina in the late 19th century

Two million Italians emigrated to Argentina between 1880 and 1920, many of them the poor who regularly ate pizza.

By 1882, Italians owned 126 of the 198 bakeries in Buenos Aires, as well as the majority of shops selling butter, cheese, and pasta.

Called placenta (with a hard "c"), the holiday dish consisted of sheets of rolled-out dough layered with cheese. It is the first recipe documenting the combination of the two elements.

A look at what was on the menu for ancient Romans

"Delicious Italy" is a website exploring the food culture of various Italian cities and regions, and in this article, the editors explore what is known about the diet of ancient Romans. Olives (and their oil) were a key daily essential, alongside grains like barley, millet, and spelt flour. Where meat was found it was most often ox, pork, deer, lamb, and even pigeons. Middle Eastern fruits like cherries and peaches could last long enough to travel to Roman cities around the Mediterranean, and candy-friendly dates were sourced from Africa. Explore this and much more at Delicious Italy.

When exactly did Mount Vesuvius erupt in ancient Rome?

Historians used to point to the summer of 79 CE when talking about the volcano that destroyed part of ancient Rome, claiming it occurred August 24, per the sole eyewitness account.

This article explores new evidence that possibly shifts the deadly disaster to that fall.

The bizarre 1920 proposal to form a pizza-shaped central European state

In light of the challenges of the Treaty of Versailles, which concluded the Great War, a mostly unknown author, and son of the map's printer, PA Maas suggested central Europe be integrated into a single state.
