Frontiers are generally understood as a line or a border separating two countries. In modern USA they also represented the western territories, where settlers began to move to live in the 19^th century. Today, frontiers are at the centre of debate on global migration, being them the limit between Mexico and the United States or the wider Mediterranean, separating Europe from Africa and the Middle East, at the centre of a global movement of people. The notion of frontier is also used to characterize the limits of the Roman empire, at the time of the construction of physical barriers, such as Hadrian’s wall, the German limes and the Fossatum Africae. But what does the term really mean? And how looking at the Roman past can help our understanding of modern frontiers?
