In honor of today’s date, I’d like to tell you all about something that happened in 411 AD. You see, a few years prior, this Roman military leader named Flavius Claudius Constantinus — who had been stationed in Britain to defend Roman settlements from the Scots, Picts, and Saxons — rose to power and was declared Emperor Constantine III by his fellow soldiers. Anyway, in 411 AD, the rightful heir to the Western Roman Empire (Honorius) sent a couple of generals up to Britain to take down Constantine, and he was eventually beheaded. But the most interesting part is that, according to legend, Constantine was the father of Uther Pendragon, and thus the grandfather of King Arthur.
