Maniakes first became prominent during a campaign in 1030–1031, when the Eastern Roman Empire was defeated at Aleppo but went on to capture Edessa from the Arabs. His greatest achievement was the partial reconquest of Sicily from the Arabs beginning in 1038. Here, he was assisted by the Varangian Guard, which was at that time led by Harald Hardrada, who later became king of Norway. There were also Norman mercenaries with him, under William de Hauteville, who won his nickname Iron Arm by defeating the emir of Syracuse in single combat. However, he soon ostracised his admiral, Stephen, whose wife was the sister of John the Eunuch, the highest ranking man at court, and, by publicly humiliating the leader of the Lombard contingent, Arduin, he caused them to desert him, with the Normans and Norsemen. In response, he was recalled by the emperor Michael IV, also brother-in-law of Stephen. Although the Arabs soon took the island back, Maniakes' successes there later inspired the Normans to invade Sicily themselves. Maniakes' accomplishments in Sicily were largely ignored by the Emperor, and he revolted against Constantine IX in 1042, though he had been appointed catepan of Italy. The individual particularly responsible for antagonizing Maniakes into revolt was one Romanus Sclerus. Sclerus, like Maniakes, was one of the immensely wealthy landowners who owned large areas of Anatolia - his estates neighboured those of Maniakes and the two were rumoured to have attacked each other during a squabble over land. Sclerus owed his influence over the emperor to his famously charming sister Sclerina, who, in most areas was a highly positive influence on Constantine. Finding himself in a position of power, Sclerus used it to poison Constantine against Maniakes - ransacking the latter's house and even seducing his wife, using the charm his family were famed for. Maniakes' response, when faced with Sclerus demanding that he hand command of the empire's forces in Apulia over to him, was to brutally torture the latter to death, after sealing his eyes, ears, nose and mouth with excrement. Maniakes was then proclaimed emperor by his troops and marched towards Constantinople. In 1043 his army clashed with troops loyal to Constantine near Thessalonika, and though initially successful, Maniakes was killed during the melee after receiving a fatal wound. Constantine's extravagant punishment of the surviving rebels was to parade them in the Hippodrome, seated backwards on donkeys. With his death, the rebellion ceased. In Sicily, the town of Maniace and the Syracusan fortress of Castello Maniace are both named after him.
