RESIDENTS OF ANCIENT Egypt, Rome and Greece enjoyed flatbread with toppings, according to History.com. But Naples, Italy, was the birthplace of the modern pizza in the late 18th or early 19th century.

Italian immigrants who came to the United States in the early 20th century introduced pizza. Canada’s first pizzeria opened in Montreal in 1948, and Greek-born Canadian Sam Panopoulos put his own spin on the circle by inventing the Hawaiian variety in 1962. Today, you can enjoy pizza almost anywhere, including at Costco.
