The common belief is that Italians invented the pizza, however the origins go back to the ancient times.
Even though we have yet to uncover archeological evidence of a Dominos Pizza before the last century, it is known the Babylonians, Israelites, Egyptians and other ancient Middle Eastern cultures were eating flat, un-leaven bread that had been cooked in mud ovens. The bread was much like a pita, which is still common in Greece and the Middle East today. Further it is known that ancient Mediterranean people such as the Greeks, Romans and Egyptians were eating the bread, topped seasoned with olive oil and native spices.
So, I guess one could argue that while the Italians didn’t invent pizza, they definitely perfected it.
