Pizza is a baked pie of Italian origin consisting of a shallow bread-like crust covered with seasoned tomato sauce, cheese, and often other toppings such as sausage or olive. The world pizza is believed to be from an Old Italian word meaning "a point," which in turn became the Italian word "pizzicare," which means "to pinch" or "pluck."The pizza could have been invented by the Phoenicians, the Greeks, or The Romans or anyone, in fact, who learned the secret of mixing flour with water and heating it on a hot stone. In one of its many forms, pizza has been a basic part of the Italian diet since the Stone Age. This earliest form of pizza was a crude bread that was baked beneath the stones of the fire. After cooking, it was seasoned with a variety of different toppings and used instead of plates and utensils to sop up broth or gravies. It is said that the idea of using bread as a plate came from the Greeks who ate flat round bread (plankuntos) baked with an assortment of toppings. It was eaten by the working man and his family because it was a thrifty and convenient food.6th Century B.C. - At the height of the Persian Empire, it is said that the soldiers of Darius the Great (521-486 B.C.), accustomed to lengthy marches, baked a kind of bread flat upon their shields and then covered it with cheese and dates.3rd Century B.C. - Marcus Porcius Cato (234-149 B.C.), also know as Cato the Elder, wrote the first history of Rome.

They sate; and (not without the god's command). Their homely far dispatch'd, the hungry band invade their trenchers next, and soon devour to mend the scenty meal, their cakes of flour...See, we devour the plates on which we fed."1st Century A.D. - Our knowledge of Roman cookery derives mainly from the excavations at Pompeii and from the great cookery book of Marcus Gavius Apicius called "De Re Coquinaria." Apicius was a culinary expert and from his writings, he provided us with information on ancient Roman cuisine. It is recorded that so great was Apicius' love of food that he poisoned himself for fear of dying of hunger when his finances fell into disarray. Apicius' book also contains recipes which involve putting a variety of ingredients on a base of bread (a hollowed-out loaf). The recipe uses chicken meat, pine kernels, cheese, garlic, mint, pepper, and oil (all ingredients of the contemporary pizza). The recipe concludes the instruction "insuper nive, et inferes" which means "cool in snow and serve!"79 A.D. - In the ashes after Mount Versuvius erupted and smothered Pompeii on August 24, 79 A.D., evidence was found of a flat flour cake that was baked and widely eaten at that time in Pompeii and nearby Neopolis, The Greek colony that became Naples.

He prepared three kinds of pizzas: one with pork fat, cheese, and basil; one with garlic, oil, and tomatoes; and another with mozzarella, basil, and tomatoes (in the colors of the Italian flag). The Queen liked the last kind of pizza so much that she sent to the pizzzaiolo a letter to thank him saying, "I assure you that the three kinds of pizza you have prepared were very delicious." Raffaele Esposito dedicated his specialty to the Queen and called it "Pizza Margherita." This pizza set the standard by which today's pizza evolved as well as firmly established Naples as the pizza capitol of the world.In the late 19th century, pizza was sold in the streets in Naples at breakfast, lunch, and dinner. It was cut from a large tray that had been cooked in the baker's oven and had a simple topping of mushrooms and anchovies. As pizza became more popular, stalls were set up where the dough was shaped as customers ordered. Various toppings were invented. The stalls soon developed into the pizzeria, an open-air place for people to congregate, eat, drink, and talk.Pizza migrated to America with the Italians in the latter half of the 19th century. Pizza was introduced to Chicago by a peddler who walked up and down Taylor Street with a metal washtub of pizzas on his head, crying his wares at two cents a chew. This was the traditional way pizza used to be sold in Naples, in copper cylindrical drums with false bottoms that were packed with charcoal from the oven to keep the pizzas hot. The name of the pizzeria was embossed on the drum.20th Century.1905 - Gennaro Lombardi claims to have opened the first United States Pizzeria in New York City at 53 1/2 Spring Street.
