The Unity of the Brethren (Unitas Fratrum / Bohemian Brethren / Jednota bratrská)
This was the most important organized group that Kramer and other inquisitors targeted in the region.
Founded 1457 in Bohemia, in the aftermath of the Hussite Wars (1419–1434). It grew out of the more radical, pacifist wing of the Hussite movement (followers of Jan Hus).
Key characteristics:
- Strict moral discipline and simple lifestyle.
- Emphasis on the Bible, education, and vernacular worship.
- Rejection of war, oaths in some cases, and certain Catholic rituals.
- They organized themselves into disciplined communities with elected leaders.
- They were persecuted by both the Catholic Church and the more moderate Utraquist Hussites.
By the late 15th/early 16th century, the Unity of the Brethren had become one of the strongest non-Catholic Christian groups in Bohemia and Moravia. Catholic authorities often lumped them in with “Waldensians/Picards.”
After the Battle of White Mountain (1620) and the Habsburg Counter-Reformation, most were driven underground or into exile. Many eventually became the Moravian Church (famous in the 18th century under Count Nikolaus von Zinzendorf in Germany). They are known today for their missionary work, education, and hymn tradition.
