We covered Roman frontiers in Britain, Jordan, Egypt, and the Neverlands... We thought its time for the largest one; the Rhine frontier! It is often said that Augustus founded and built the Roman border with the Rhine, that he installed stone forts along it, and that it was an unshakable border meant to repel any invasion. This video aims to dispel the above myths and shed some light on Roman borders. It wasn't one emperor who built it, it took decades for the wooden forts to slowly become permanent stone ones, and the border was very dynamic network that shifted through the centuries! This video covers the grand strategy of the Rhine frontier and explains how Roman borders worked, as well as how Rome built its largest border. (Defense in depth - How Rome guarded its LARGEST border)
