Hesse

In the War of the Thuringian Succession (1247–64), Hesse gained its independence and became a Landgraviate within the Holy Roman Empire. In 1567, the territory was divided up into four lines: Hesse-Kassel (or Hesse-Cassel), Hesse-Darmstadt, Hesse-Rheinfels, and the also previously existing Hesse-Marburg.
