One of a religious sect called the United Brethern (an offshoot of the Hussites in Bohemia), which formed a separate church of Moravia, a northern district of Austria, about the middle of the 15th century. After being nearly extirpated by persecution, the society, under the name of The Renewed Church of the United Brethren, was reestablished in 1722-35 on the estates of Count Zinzendorf in Saxony. Called also Herrnhuter.
