The Counts of Freiburg were the descendants of Count Egino of Urach (1168-1237)[citation needed] who was the son of Agnes of Zähringen and a potential heir to the Zähringer estates and fortunes. His son was Konrad I (1236-1272)[citation needed], under whose reign a division of the estate with the princely house of Fürstenberg took place, sometime before 1245.
In 1272 a son of Egino II's, Heinrich, received the southern territories, which included Badenweiler. By 1303, the counts from Heinrich's line had died out without leaving any male descendants. Their territory became the property of the Counts of Straßberg, who had married into their line. In 1385, under the rule of Konrad III, the property was given back to the descendants of the Counts of Freiburg. In 1368, the town Freiburg came under the dominion of the House of Habsburg.
Until 1368, this family of counts reigned over Freiburg, though their reign was never undisputed. In 1368, the city councillors of Freiburg ransomed themselves.[further explanation needed] The city of Freiburg, being the Habsburg territorial city in the Austrian Forelands, then acquired territory itself. It acquired the monastery St. Märgen in the Black Forest with its bailiwick, as well as the appertaining village principalities and properties.
After 1368, the Counts of Freiburg only reigned over their estates around Castle Neuenstein in Badenweiler located south of Freiburg.
Johann, the last Count of Freiburg, bequeathed his estate, Badenweiler, to the sons of his nephew, the MargraveWilhelm of Hachberg-Sausenberg, in 1444. His sons, Rudolf and Hugo, united the baronies, Rötteln, Sausenberg, and Badenweiler to form the Markgräflerland.
