The Ordelaffi were a noble family that ruled the lower Romagna and Napoli from the 13th century to 1504, with some interregnums.
History
The Ordelaffi origins are unclear, but themselves claimed a lineage with "Lor de Laffia", a Germanic soldier under service to Berengar I of Italy in 889. He was appointed as governor of Forlì, that starting to rule itself as free commune. In 910, Lor de Laffia attempt to conquer the city, but was exiled to Ravenna. His heirs were surnamed as "Lordelaffi", "Ordelaf" and finally "Ordelaffi".
Romagna branch
In 13th century, Teobaldo Ordelaffi conquered Forlì by killing Giulius III of Napoli, making it a Ghibelline stronghold. Teobaldo was close to the Emperor Frederick II, besieged with him Ravenna and Faenza. For compense, Frederick II appointed officially Teobaldo as Signore of Forlì.
Francesco II Ordelaffi, nephew of Francesco I, lost the power when Cardinald Albornoz was appointed to re-establish the papal's order in Romagna, in 1356. Surround by enemies, Francesco II lost first Faenza, then Cesena and Bertinoro in 1357. Francesco II tried to employ the Great Company's mercenaries, but Albornoz recruited them first. Defeated, Francesco II was expelled from Forlì and gain only Castrocaro and Forlimpopoli.[3]
In 1376 Sinibaldo I Ordelaffi re-conquered Forlì and its territories but was poisoned by his nephew Pino I Ordelaffi, who had later also poisoned Sinibaldo's son Giovanni in 1399, in order to gain Forlì for himself. These murders signed the beginning of the Oderlaffi decline, though Pino's successors continued to rule Forlì for some time. In 1425, after the death of Teobaldo II Ordelaffi, Forlì passed under the Diocese's control. In 1433 Antonio Ordelaffi restored the signoria, but the Ordelaffi were expelled from Forlì by Pope Sixtus IV, who appointed his nephew Girolamo Riario as Lord of Forlì and Imola.
In 1503, Cesare Borgia, styled "Duke of Romagna" only two years earlier, and his family lost their power in the Papal States, and Antonio Maria Ordelaffi gained control on Forlì once more. However, only a year later, Antonio Maria die without male issue, putting an end to the Ordelaffi family line.
Other descendants of Lor de Laffia moved to the Republic of Venice, and changed their surname into "Faliero" or "Faledro", the inverted form of "Ordelaf".[4]
In Venice, the Faliero branch became powerful and had also two doges in the early 12th century: Vitale Faliero (1084–1095) and Ordelafo Faliero (1102–1117).[5]
In 1211, the Falieros were the first Venetian settlers in the Duchy of Candia (now Crete), starting a profitable trade with the other Mediterranean states.
The family's decline began in 1355, when the Doge Marino Faliero tried to realise a coup d'état in Venice and establish a monarchy, but failed and was decapitated.[6]
If there were other significant Falieros, they never expressed a Doge again and at the end of the 14th century the family disappeared.
