BTW about the Mayflower, the Pilgrims and Thanksgiving, I've read an interesting story:
The First Thanksgiving was celebrated to give thanks to God for helping the Pilgrims of Plymouth Colony survive the brutal winter. However God didn't show up (as usual) but instead the Plymouth settlers celebrated a harvest feast after a successful growing season thanks to a native.
In fact, a Patuxet Native American who resided with the Wampanoag tribe, taught the Pilgrims how to cultivate in these new lands. That Native American was Squanto who finally settled with Pilgrims at the site of his former village, which the English named Plymouth. He helped them recover from an extremely hard first winter by teaching them techniques to increase food production: by fertilizing crops. He also showed them the best places to catch fish and eels. He was critical to their survival.
The Pilgrims set apart a day to celebrate at Plymouth immediately after their first harvest, in 1621. At the time, this was not regarded as a Thanksgiving observance; harvest festivals existed in English and Wampanoag tradition alike.
How ironic History reversed each roles just like in The First Thanksgiving
