During 1180–1250, the counts of Kyburg existed as a separate cadet line of the counts of Dillingen. The county was ruled by Hartmann V, nephew of the last count of Kyburg in the agnatic line, during 1251–1263. It then passed to the House of Habsburg as possession of the counts of Neu-Kyburg (also Kyburg-Burgdorf) after the extinction of the agnatic line of the House of Kyburg, until the extinction of Neu-Kyburg in 1417. It then passed under direct Habsburg suzerainty, then briefly to Zürich (1424–1442), to emperor Frederick III (1442–1452) and back to Zürich in 1452, from which time it was administered as a bailiwick (Landvogtei) of Zürich until the establishment of the Helvetic Republic in 1798.
Despite not being in possession anymore, the Habsburg monarchs continued carrying the historic title of "Princely Count of Kyburg" in the grand title of the Emperor of Austria.
