The movement inaugurated in England by the Wesleys has received and is still receiving much attention from historians. There was a contemporary and related movement in Wales, but, due to barriers of language, geography, politics, and national outlook, it has received much less attention. The leader of the Welsh movement was Howell Harris: the discovery and piecemeal publication of his journals and of a great mass of his correspondence have provided fresh material for the study of his life and work, and, in particular, of his relationship to the Wesleys.
