The first Thanksgiving feast, of course, was celebrated with a Native American tribe that had just saved us all from dying of starvation over the winter.
Some 50 years after that Thanksgiving feast, we waged a huge war of genocide against that same tribe.
Their Chief at the time was the son of the Chief who had saved us 50 years earlier. When he was captured, he was beheaded and his head was mounted on a pole in downtown Boston for 20 years.
When we captured his son, a nine year old boy, we sold him into slavery in the Caribbean.
PBS American Experience does a good job of telling the story, but you can only get the episode these days through iTunes.
There is an iTunes download button on their webpage:
I don’t know if iTunes charges for the download (I’m on dialup, so big downloads aren’t something I have a lot of experience with). I tried to figure that out, but they wouldn’t let me see unless I downloaded and installed iTunes first.
