With the start of the English Civil War in 1642, emigration came to a comparative standstill, and some colonists even returned to England to fight for the Parliamentary cause. In the following years, most of the immigrants came for economic reasons; they were merchants, seamen, and skilled craftsmen. Following the revocation of the Edict of Nantes in 1685, the colony also saw an influx of French Protestant Huguenots. During the period of the charter colony, small numbers of Scots immigrated, but these were assimilated into the colony. The population of Massachusetts remained largely English in character until the 1840s.
