Zinzendorf married Erdmuth Dorothea von Reuss, a cousin, and assumed his duties as a young noble in the courst of King August the Strong. In 1722, he was approached by a group of Moravians to request permission to live on his lands. He granted their request, and a small band crossed the border from Moravia to settle in a town they called Herrnhut, or "the Lord's Watch." Zinzendorf was intrigued by the story of the Moravians, and began to read about the early Unity at the library in Dresden. His tenants went through a period of serious division, and it was then in 1727 that Zinzendorf left public life to spend all his time at his Berthelsdorf estate working with the troubled Moravians. Largely due to his leadership in daily Bible studies, the group came to formulate a unique document, known as the "Brotherly Agreement," which set forth basic tenets of Christian behavior. Residents of Herrnhut were required to sign a pledge to abide by these Biblical principals. There followed an intense and powerful experience of renewal, often described as the "Moravian Pentecost." During a communion service at Berthelsdorf, the entire congregation felt a powerful presence of the Holy Spirit, and felt their previous differences swept away. This experience began the Moravian renewal, and led to the beginning of the Protestant World Mission movement.
