Biography

Conrad IV's life was a brief, tragic coda to the epic saga of the Hohenstaufen dynasty. Born to the formidable Emperor Frederick II and the Queen of Jerusalem, he was a royal heir from his first breath, inheriting the title of King of Jerusalem as a toddler. His father secured his election as King of Germany, but Conrad's reign was never his own—it was a piece in Frederick's grand, fractious game against the Pope and northern Italian cities. After Frederick's death in 1250, the 22-year-old Conrad was left with a poisoned inheritance: the Kingdom of Sicily under papal interdict and a German throne contested by rival claimants. He marched south to secure Sicily, his most tangible realm, and seemed on the verge of success when malaria struck him down at 26. His death extinguished the direct male Hohenstaufen line and plunged the empire into a two-decade interregnum.

Did You Know?

He was the only son of Emperor Frederick II born in lawful wedlock to survive infancy.

His death from malaria in a military camp in southern Italy effectively ended the Hohenstaufen line.

His posthumous son, Conradin, was executed at 16, finally extinguishing the dynasty.

He was contemporaneously known as Conrad the Younger to distinguish him from his father.

“My father's crown is a heavy inheritance, and my enemies are many.”
