The origins of bologna can be traced right back to the Bronze Age. Around three thousand years ago, a population of unkown origin settled in the Appenine region, on the banks of the Apose and Ravone rivers. During the Iron Age, this population developed its own authentic culture and came to be known as the Villanovan Culture.
The Italian city named Bologna does date back to the Villanovan culture, but that answer is a bit of a stretch; for all practical purposes, the food we call bologna can be traced to a similar Italian sausage named mortadella, which does come from the Bolognese region of Italy. Bologna is an American sausage that dates to the late nineteenth century.
