In the winter of 1620, a group of about a hundred people set off for America on a boat called The Mayflower. About half were English religious separatists. They first landed near Provincetown, but eventually settled off the Cape Cod bay, in an area they named Plymouth. Legend has it that they first stepped onto land at a big rock, called Plymouth Rock (however, there is no real evidence of this).

When was the first Thanksgiving? And why?
