CONRADEN, Bavarian royalty, born (d: 1268); called the Younger or the Boy, but usually known by the diminutive Conradin (German: Konradin, Italian: Corradino), was the Duke of Swabia (1254–1268, as Conrad IV), King of Jerusalem (1254–1268, as Conrad III), and King of Sicily (1254–1258, de jure until 1268, as Conrad II). He was born in Wolfstein, Bavaria, to Conrad IV of Germany and Elisabeth of Wittelsbach.

He is sometimes known as Conrad V, though he never succeeded his father in Germany. Conradin was the last legitimate Hohenstaufen, the son of the assassinated Conrad IV. We know little of his appearance and character except that he was “beautiful as Absalom, and spoke good Latin”.

While he was still a child in Germany, his uncle Manfred made himself king of Sicily (1258), but when Manfred died eight years later, the kingdom was seized by Charles of Anjou. Conradin was persuaded to come to Italy to recover his kingdom, and, accompanied by his lover, Frederick of Baden, titular Duke of Austria, he gained the support of several Italian cities. In the end, however, Conradin was captured by Charles, tried as a traitor and beheaded. His lover, at his own request, was executed with him. Conradin was just sixteen; Frederick was twenty-one. To this day Gay lovers make pilgrimages to the church of the monastery of Santa Maria del Carmine at Naples, where the two young men were laid to rest, together.
