A new state formed around the tribe of Premyslids, who founded the Duchy of Bohemia. The duchy existed largely within the sphere of influence of the East Franconia and later the Holy Roman Empire. The duchy sided with the Roman Catholic Church during the East-West Schism and in 1212, the duke Ottokar I was granted the hereditary title of king for his service to the Holy Roman Emperor Frederick II. The Přemyslid dynasty died out at the start of the 14th century and was replaced by the Luxembourg dynasty. The most notable of the Luxembourg rulers was the Charles IV, who was elected the Emperor of the Holy Roman Empire. He established the Archbishopric of Prague and the Charles University, the first university north of Alps and east of Paris. The start of the 15th century saw the rise of Proto-Protestantic sentiments in the Czech lands. The execution of Jan Hus sparked the Hussite Wars and the religious split that followed them. The Jagiellon dynasty ascended the Czech throne in 1471. They ruled for half a century before the king Louis Jagiellon died in the Battle of Mohács and the empty throne was given to the House of Habsburg.
