It took Star Wars: The Force Awakens just 20 days to become the number one North American movie of all time. Obi Wan Kenobi might say the movie has become more powerful than we could possibly imagine.

In the video below, Lenoir-Rhyne University Professor Amy Sturgis discusses historical inspirations behind Star Wars as well as other parallels between the Jedi order and warriors throughout history. Star Wars may have taken place in a galaxy far, far away, but many of its battles have also been played out here on Earth.
