interest. Harris and Williams undertook major preaching journeys, starting in South Wales but later venturing north. As they preached they made converts, whom they then gathered together into organised groups of fellowships (known as seiadau (societies) in Welsh). As more and more converts were made, more and more evangelists were also created, and by 1750 there were over 400 such fellowship groups in Wales . These groups were closely supervised by the leaders and were built up into a significant and powerful network within the Church of England. Rowland concentrated his efforts on Llangeitho which became a centre for the movement. On Communion Sundays thousands of the members of the seiadau would travel there to receive the sacrament. A Calvinist movement The Welsh Methodist revival differed from the Methodist revival in England in that its theology was Calvinist rather than Arminian. At the beginning the leaders worked with John Wesley, but gradually they parted company from Wesley and became associated with George Whitfield and his patron, Selina, Countess of Huntingdon. Welsh Methodists and other denominations The Methodist revival began within the Church of England in Wales and at the beginning remained as a group within it. But its success meant that Methodists gradually built up their own networks, structures, and even meeting houses (or chapels), which led eventually to the secession of 1811 and the formal establishment of the Calvinistic Methodist Presbyterian Church of Wales in 1823. The Welsh Methodist revival also had an influence on the older nonconformist churches, or dissenters — the Baptists and the Congregationalists — who in turn also experienced growth and renewal. As a result, by the middle of the nineteenth century, Wales was predominantly a nonconformist country. Sources . James, E.
