Enzo of Sardinia
Enzo (or Enzio; c. 1218 – 14 March 1272) was an illegitimate son of the Hohenstaufen emperor Frederick II, who appointed him 'King of Sardinia' in 1238. He played a major role in the wars between Guelphs and Ghibellines in the Imperial kingdom of Italy, and was captured by his enemies in 1249. He remained imprisoned in Bologna until his death.
Enzo was a natural son of Frederick II by a certain Adelaide, possibly a member of the Swabian noble House of Urslingen and relative of Duke Conrad I of Spoleto. He was the eldest of the emperor's illegitimate sons and allegedly the favourite one. He had a pleasant personality, a strong physical resemblance to his father, and also shared his love for the arts. Enzo fought in the ongoing wars of his father with Pope Gregory IX and the Northern Italian communes of the Lombard League.
When Ubaldo Visconti died in 1238, the Doria noble family of Genoa, in order to secure the Sardinian Giudicato of Logudoro from Pisan domination, convinced the emperor to marry Enzo to Ubaldo's widow, Adelasia of Torres (d. 1255). Upon the marriage, Enzo by jure uxoris would accede to the Sardinian Giudicati of Logudoro (Torres) and Gallura, covering the northern half of the Sardinia island. He was created a knight in Cremona and granted the Sardinian royal title, last held by Barisone II of Arborea in 1164/65. Enzo travelled to the island to marry Adelasia in October that year.
In July 1239, he was assigned as Imperial vicar general in Lombardy, as well as General-Legate in Romagna, and left Sardinia never to return. In 1241, he took part in the capture of a papal fleet at the Battle of Giglio in the Tyrrhenian Sea. His first successful move as military leader was the reconquest of Jesi, in the Marche, which was Frederick's birthplace. Later he was captured in a skirmish against the Milanese at Gorgonzola, but soon released. In 1245 or 1246 his marriage was annulled. In 1247, he took part in the unsuccessful Siege of Parma and continued to fight the Guelph Lombards, assaulting Reggio and conducting an assault in the surroundings of Parma.
During a campaign to support the Ghibelline cities of Modena and Cremona against Guelph Bologna, he was defeated and captured on 26 May 1249 at the Battle of Fossalta. Though the emperor demanded his release, Enzo was thenceforth kept a knightly prisoner in Bologna, in a palace that came to be named Palazzo Re Enzo after him. Every attempt to escape or to rescue him failed, and he died after more than 22 years in captivity. After the death of his half-brothers Conrad IV in 1254, Frederick of Antioch in 1256 and Manfred in 1266, as well as the execution his nephew Conradin in 1268, he was the last of the Hohenstaufen heirs.
Enzo shared the father's passion for falconry, and was thus nicknamed Falconello ("little falcon"). He was the dedicatee of a French translation of a hunting treatise by Yatrib. Like his brother Manfred, he presumably grew fond of poetry at Frederick's court: during his long imprisonment Enzo wrote several poems, two of his canzoni and a sonnet (Tempo vene che sale chi discende) are preserved. His pitiful fate and the fall of the Hohenstaufen dynasty was itself a source of inspiration for several poets, such as the Italian lyricist Giovanni Pascoli (Canzoni di re Enzio, 1909).
