Let it be known that I am forever using goofy history videos while teaching, usually to make my students laugh (but also, sneakily to teach them). My favorites are John Green's Crash Course and Horrible Histories, but I just found this one from Historyteachers on Theodora.
It's two minutes of your life, but if you want a down and dirty synopsis of Theodora's life (complete with the 30,000 corpses after the Nika revolt), this is pretty darn awesome.
Also, just a side note...
It's only nine days until The Secret History: A Novel of Empress Theodora hits the shelves!
