John Knox (1505–1572), a Scot who had spent time studying under Calvin in Geneva, returned to Scotland and urged his countrymen to reform the Church in line with Calvinist doctrines.
In England, Presbyterianism was established in secret in 1592. Thomas Cartwright is thought to be the first Presbyterian in England. Cartwright's controversial lectures at Cambridge University condemning the episcopal hierarchy of the Elizabethan Church led to his deprivation of his post by Archbishop John Whitgift and his emigration abroad. Between 1645 and 1648, a series of ordinances of the Long Parliament established Presbyterianism as the polity of the Church of England. Presbyterian government was established in London and Lancashire and in a few other places in England, although Presbyterian hostility to the execution of Charles I and the establishment of the republican Commonwealth of England meant that Parliament never enforced the Presbyterian system in England.
Some, such as Crown Court (Covent Garden, London), St Andrew's (Stepney, London) and Swallow Street (London), did not join the English denomination, which is why there are Church of Scotland congregations in England such as those at Crown Court, and St Columba's, Pont Street (Knightsbridge) in London.
Presbyterianism first officially arrived in Colonial America in 1644 with the establishment of Christ's First Presbyterian Church in Hempstead, New York. The Church was organized by the Rev. Richard Denton.
Another notable church was established in 1703 the first Presbytery in Philadelphia. In time, the presbytery would be joined by two more to form a synod (1717) and would eventually evolve into the Presbyterian Church in the United States of America in 1789.
