The centuries-long rise of the Austrian House of Habsburg had already begun with King Rudolph's victory at the 1278 Battle on the Marchfeld and the final obtainment of the Imperial crown by Emperor Frederick III in 1452. His descendants Maximilian I and Philip the Fair by marriage gained the inheritance of the Burgundian dukes and the Spanish Crown of Castile (tu felix Austria nube), and under Emperor Charles V, the Habsburg realm evolved to a European great power. In 1526 his brother Ferdinand I inherited the Lands of the Bohemian Crown as well as the Kingdom of Hungary outside the borders of the Empire, laying the foundation of the Central European Habsburg Monarchy.
