Page "House of Habsburg" Paragraph 1

The House takes its name from Habsburg Castle, a fortress built around 1020 – 1030 in present day Switzerland by Count Radbot of Klettgau, who chose to name his fortress Habsburg.

His grandson, Otto II, was the first to take the fortress name as his own, adding " von Habsburg " to his title.

The House of Habsburg gathered dynastic momentum through the 11th, 12th and 13th centuries.
