By Ahmad Thomson & Muhammad Ataur Rahman. The history of Islam in Spain must be understood in the context of how the official religion of Christianity developed in Europe, especially in regards to the interaction between the Unitarian and the Trinitarian Christians. This work traces the movement of the original Unitarian followers of Jesus, peace be upon him, from North Africa and the Middle East up into Europe and Spain, describing the formation and expansion of the Trinitarian Church in Italy and the rest of Europe and the almost total annihilation of the Unitarian Christians at the hands of the Trinitarian Church by the Means of Medieval Inquisition.
