Burchard IV of Hohenberg
Burchard IV of Zollern-Hohenberg (died before 1225) was a Swabian count, the son of Count Burchard III and Kunigunde of Grünberg. In 1207 he and his brother Albert, as counts of Zollern, witnessed a charter of King Philip of Swabia at Strasbourg.
He is attested as count of Hohenberg from 1213, when he appeared at Constance and Überlingen, and in 1216–1217 he attended proceedings of King Frederick II in Constance and Rottweil.
He married Wilipirg of Aichelberg, who bore him his successor Burchard V and a daughter Kunigunde. His granddaughter Gertrud Anna married Rudolf of Habsburg, the later German king.
