Our children have been studying the Reformation during their history lessons. We all like to supplement our history with some videos (usually on Youtube), and of course their favourite show to watch is "Horrible Histories". It has a little bit on lots of different subjects, although it's often a little bit light on.
Today I found four great short videos on the Reformation that were easy to watch, fairly good on facts and explanations (with no derogatory statements about Christians) and with no "reenactment" scenes (which at this time tend to be rather violent). Under the title: Introduction to the Protestant Reformation, the four videos are: Setting the Stage, Martin Luther, Varieties of Protestantism, and The Counter-Reformation.
