The 16th, 17th and 18th centuries were heavily dominated by Lutheran orthodoxy. In addition, the Reformed faith made inroads with the so-called crypto Calvinists, but was strongly persecuted in an overwhelmingly Lutheran state. In the 17th century, Pietism became an important influence. In the 18th century, the Moravian Church was set up on Count von Zinzendorf's property at Herrnhut.
