The Pilgrims embarked on their legendary Mayflower voyage in 1620 in search of religious freedom and a better life. The settlers were unprepared for the hardships they would face at the end of their journey, but with the help of their neighbor Indians, the Pilgrims survived the first year in their new world. Then, when their fall harvest was plentiful, the Pilgrims and the Indians joined together in a three-day celebration, the first Thanksgiving.
