Italian newspaper La Repubblica reports that food historian Giuseppe Nocca will present his research Thursday on a Latin document from 997 AD, believed to be the oldest reference to the word pizza.
The 1,017-year-old document was written in Gaeta, a small village on the border between Campania and Lazio in Italy.
In the document, the son of a feudal lord promises 12 pizzas to the local bishop as a yearly homage.
In case you're wondering, the name Margherita is actually Neapolitan. The pizza with tomato and mozzarella was named in honour to the Queen of Italy during a visit to Naples in 1889. Her name was Margherita of Savoy.
