The 'Christian Republick' was an international community that had grown up in the wake of the dramatic religious revivals that had occurred in parts of Germany, Switzerland, Austria, France, England, Wales, Scotland and the American colonies. This chapter examines how some eighteenth-century Welsh evangelicals took advantage of their involvement in the imperial project. It looks at the extent of the stake which many of them had in Britain's ever-expanding empire through their support and communication with missionaries who had left Wales to serve overseas. The chapter proceeds with a detailed examination of the Welsh Methodists' participation in the international evangelical community that grew from the evangelical revivals. It suggests that the development of evangelical Protestantism in Wales was informed by involvement in a spiritual empire that brought coreligionists from around the Atlantic basin into contact with and mutual dependence upon one another.
