The Moravian Church, also known as the Unitas Fratrum, originated in the early 15th century in what is now the Czech Republic. It was founded by followers of John Huss, a reformer who advocated for religious and social change. The church emphasized community, education, and missionary work, spreading its influence across Europe and later to the Americas. In the 18th century, the Moravians established a significant presence in Pennsylvania, where they founded settlements like Bethlehem and Nazareth. They became known for their commitment to music, education, and social welfare, contributing to the cultural landscape of early America while maintaining their distinct religious practices.
