Plymouth's early history extends to the Bronze Age, when a first settlement emerged at Mount Batten. This settlement continued as a trading post for the Roman Empire, until it was surpassed by the more prosperous village of Sutton, now called Plymouth. In 1620, the Pilgrim Fathers departed Plymouth for the New World and established Plymouth Colony – the second English settlement in what is now the United States of America. During the English Civil War the town was held by the Parliamentarians and was besieged between 1642 and 1646.
