1. Definition
The Unitas fratrum or Moravians, German Herrnhuter or Brüdergemeine, date from the 1720s as a collective and revivalist movement (Revivalist movements) within Pietism. In the second half of the 18th century, they developed into an independent Christian denomination, which spread throughout many areas of Protestant Europe as well as in numerous non-European countries and colonial territories, thanks to their missionary work (Mission) and evangelism.
