There are many theories for the origin of the name "carbonara", which is likely more recent than the dish itself. Since the name is derived from "carbonaro" (the Italian word for 'charcoal burner'), some believe the dish was first made as a hearty meal for Italian charcoal workers. In parts of the United States, this etymology gave rise to the term "coal miner's spaghetti". It has even been suggested that it was created as a tribute to the "Carbonari" ('charcoalmen') secret society prominent in the early, repressed stages of Italian unification in the early 19th century. It seems more likely that it is an "urban dish" from Rome, perhaps popularized by the restaurant La Carbonara in Rome.
