In 1620, 102 Pilgrims traveled from England to North America on the Mayflower and arrived in present-day Massachusetts in the winter. Half of the Pilgrims did not survive the first winter due to lack of food and shelter. The following year, in 1621, the surviving Pilgrims had their first successful corn harvest, which they celebrated for three days with the local Wampanoag tribe, who had taught the Pilgrims how to survive. This celebration is now regarded as the first Thanksgiving. It took over 100 more years for Thanksgiving to become an official national holiday, with Abraham Lincoln declaring the last Thursday in November as a national day of Thanksgiving in 1863.
