You think you know Thanksgiving: turkey, pie, and family. But the truth is, this holiday almost didn't happen. In the mid 1800s America was deeply divided. The holiday we know and love was just a scattering of local feasts, until one determined woman decided the whole country needed to stop and give thanks.

She wasn't a politician or a general. She was an author: Sarah Josepha Hale. For 36 years she fought a relentless battle to draw the nation together over thanksgiving.

This is the incredible story of a woman who succeeded. Enjoy!
