The House of Zähringen was a noble family that originated in the 11th century in what is now Switzerland. They played a significant role in the political landscape of the Holy Roman Empire, particularly in the regions of Baden and Fribourg. The family is known for founding several cities, including Bern and Freiburg im Breisgau. The Zähringen dynasty produced several influential rulers and contributed to the development of medieval culture and governance. Their power declined in the late 13th century, leading to the fragmentation of their territories. The legacy of the House of Zähringen remains evident in the cities and institutions they established.
