In step with the gradually unfolding imperial policies of the successive governments of King Charles I and later monarchs, the Church of England was extended to the northern part of the Western hemisphere between 1662 and 1829. Under the supervision of the Board of Trade and Plantations until 1701, and the Society for the Propagation of the Gospel in Foreign Parts from that year, decade after decade an increasing number of men of differing origins and places of collegiate education in Britain came to serve missions of the Church in early America. The ranks included natives of England, Wales, Scotland, Ireland, and the American colonies, who were supported by the SPG or the legislatures of the provinces in which the Church was established. Development was shaped by imperial policies and administration over 160 years amid rising populations, changing political situations, and the consequences of war and diplomacy.
