Nicolaus Zinzendorf was an influential 18th-century German religious and social reformer who served as a bishop within the Moravian Church. Born in Dresden in 1700, he established the community at Herrnhut to provide refuge for persecuted Moravian exiles. As a central figure in Protestantism, he helped revitalize the Unity of the Brethren and pioneered early Christian missionary efforts. His leadership and theological contributions shaped the Moravian Church, leaving a lasting impact on Protestant spiritual life through his writings and hymnody.
