Flippen American History Classes

This YouTube channel, Flippen American History Classes, has a great number of short videos covering all aspects of American history from pre-Columbian times through 2008.  The videos are organized into 44 broad topics, which are numbered, in rough chronological order, and shown on the homepage.  This is the place to begin!  If you click on the video tab across the menu bar at top instead, you can see all the videos but they are in random order.
