Person

Rudolf I of Germany (died 1291)

Rudolf of Habsburg (1 May 1218 – 15 July 1291) was a German nobleman and the first member of the House of Habsburg to become King of the Romans, reigning from 1273 until his death. Born into a relatively minor noble family, Rudolf succeeded his father as Count of Habsburg in 1240, gradually expanding his power through military campaigns, political alliances, and the construction of key fortresses such as Neuhabsburg Castle. His marriage to Gertrude of Hohenberg further strengthened his position among the Swabian nobility. During the turbulent period of the Great Interregnum, Rudolf distinguished himself both as a formidable military leader—participating in regional conflicts and even joining the Prussian Crusade in 1254—and as a restorer of order, often intervening against robber barons and feuding nobles.
