The Counts of Celje or the Counts of Cilli were the most influential late medieval noble dynasty on the territory of present-day Slovenia. Risen as vassals of the Habsburg dukes of Styria in the early 14th century, they ruled the County of Cilli as immediate counts (Reichsgrafen) from 1341. They soon acquired a large number of feudal possessions also in today's Croatia and Bosnia. They rose to Princes of the Holy Roman Empire in 1436. The dynasty reached its peak with Ulrich II of Cilli, but with his death in 1456 they also died out, and after a war of succession, the Habsburgs inherited their domains.

He was also a claimant to the Bosnian throne. He was killed by agents of the Hunyadi clan under unknown circumstances, which plunged Hungary into civil unrest that was resolved a year later by the sudden death of king Ladislas the Posthumous and the election of Matthias Corvinus, the son of John Hunyadi and Ulrich's son-in-law, as king. Ulrich's possessions in the Holy Roman Empire were inherited by Emperor Frederick III, while his possessions in Hungary were reverted to the crown.

Ulrich III was the Lord in the March of Carniola from c. 1249 and Duke of Carinthia from 1256 until his death, the last ruler from the House of Sponheim. His rule had long-lasting consequences. In Carniola, he acquired the former Meranian possessions, thus becoming the first undisputed princeps terrae, provincial lord or landgrave, creating the power and legal basis of the future Duchy of Carniola. The center of his original Carniolan possessions, Ljubljana, became the new administrative center and thus the provincial capital, as well as the center of Ulrich's power. In Carinthia, which he took over after his father's death, his seal became the coat of arms of Carinthia up to today. Despite his attempts to secure the vast Babenberg inheritance through two marriages, first to Agnes of Merania, widow of the last Babenberg duke Frederick II of Austria, and then to Frederick's niece Agnes of Baden, Ulrich remained childless. After a short interregnum by his younger brother Philip of Spanheim, patriarch of Aquileia, the House of Spanheim went extinct, and all of Ulrich's possessions were inherited by his cousin Ottokar II of Bohemia.
Frederick I of Celje, also Frederick I of Cilli, was a Styrian free noble who became the first Count of Celje, founding a noble house that would dominate Slovenian and Croatian history in the first half of the 15th century.
