Thanksgiving is an American holiday that stretches all the way back to a time long before America became a nation. The Pilgrims landed in 1620. They faced brutal conditions and were woefully unprepared. Roughly half of them died in that first year. Then they had a successful harvest of corn. In November of 1621 they decided to celebrate a feast of thanksgiving. Over the centuries, Americans continued to celebrate feasts of thanksgiving in the fall. Some presidents issued proclamations. Abraham Lincoln issued a proclamation for a perpetual national holiday set aside for thanksgiving. In 1863, with the nation torn apart by the Civil War, he declared: "I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens."
