Conradin

Conradin (1252–1268), the last heir of the Hohenstaufen dynasty, was the son of King Conrad IV and Elisabeth of Bavaria. In 1254 he inherited the Duchy of Swabia and his family's claim to Sicily, and he was raised in Bavaria.

After Charles of Anjou seized southern Italy, he crossed the Alps in 1267 to answer the Ghibelline call and entered Rome in July 1268. Charles crushed his army at Tagliacozzo on 23 August 1268.

Betrayed while trying to sail to Sicily, he was captured and taken to Naples. There Conradin was beheaded on 29 October 1268, aged sixteen, ending the Hohenstaufen male line.
