In the British Isles, there were three established churches, the Church of England, the Church of Scotland and the Church of Ireland. The Church of England had adopted the mildly Calvinistic Thirty-Nine Articles and the more explicitly Calvinistic Lambeth Articles, both of which had been written in the second half of the 16th century. The Church of Scotland adhered to the Calvinistic Scots Confession, although Scots had been forced to somewhat compromise on their ecclesiology. In 1615, the Church of Ireland adopted the explicitly Calvinistic Irish Articles, which had largely been written by James Ussher, later Archbishop of Armagh. Also in Ireland, the settling of the on the northeast part of the island Ulster Plantation by some Scottish Presbyterians led to the establishment of the Presbyterian Church in Ireland.
