The Pilgrims The Pilgrims were people of England who objected to the form of religious feeling shown to God and religious services used in the Church of England. King James punished all who refused to follow laws and traditions of the Church of England and to give money to support it. These people had to leave their country and went to Holland trying to find religious freedom there. But they were not allowed to own land in Holland and, besides, they didn’t want their children to become Dutch-speaking people. They wanted to remain English and they soon returned to England with the idea of leaving for America. In America the Pilgrims hoped to start a new life based on their own ideals of religious and civil rights. With the idea of a New England in America the Pilgrims crossed the Atlantic on the little ship “The Mayflower”. At the end of November in 1620 they landed on Cape Cod, not far from where Boston now is, and decided to form a colony. A short time after landing they found a suitable place to live and began to cut trees and build houses. Winter came on, but they were not prepared for difficult times. Many of them got ill and about half of them died. But those who survived didn’t give up. In spring and summer following that hard winter, their crops grew, and the colony became rich. They made friends with the Indians. At last, they felt sure that they found the land that they had hoped to find so long. In the autumn, they decided to have a holiday and to unite in giving thanks to God for everything they had received. They also invited the Indians and celebrated together the first Thanksgiving day in America.
