Reuss (state)
Reuss (German: Reuß) was the name of several historical states located in present-day Thuringia, Germany. Its rulers, the House of Reuss, named all of their male children Heinrich (English: Henry) after the end of the 12th century in honour of Henry VI, Holy Roman Emperor (1190–97), to whom they owed the estates of Weida and Gera. The head of each branch of the family bore the German title Fürst (Prince) as did their children.
