Thanksgiving Day is one of the most important family holiday in America. All the members of a family, no matter where far away they are, will try to get together on that day. The first Thanksgiving in America takes place in October, 1621. In 1620, the group of Englishmen sailed to Massachusetts. They had expected to find a freely place to live in, so they experienced a hard winter. Half of them starved death. The next spring, we began farming. With the help of local Indians, they learned to be plant corn and raise animals. In the autumn, the fields produced a good harvest. Filling with joy and thanks to God, they held a celebration. In 1863, it became a national holiday.
