Zinzendorf, born 1700, was a godson of Philipp Jakob Spener and educated at Halle under August Hermann Francke, the two central figures of German Pietism. He bought the Berthelsdorf estate in 1722, allowed Christian David to settle Moravian refugees on it, and within five years had effectively become their pastor, to the annoyance of the Saxon authorities, who exiled him from 1736 to 1747. He was consecrated a bishop of the Unity in 1737, spent the exile founding communities across Europe and visiting Pennsylvania and the West Indies, and died at Herrnhut in 1760. He wrote something on the order of 2,000 hymns and a great deal of theology that the church has never quite systematised. His encounter with the young John Wesley in 1738, and Wesley's subsequent visit to Herrnhut, is the direct link between the Moravians and Methodism.
