Aben Humeya was born Fernando de Valor into a Morisco family and claimed to be of noble lineage, descended from the Umayyad dynasty. However, this is improbable for the Nasrids of Granada had not in early years, based their legitimacy on Ummayad descent. The name Aben Humeya is the hispanicized version of the Arabic name Ibn Umayya meaning Son of Umayya. The name symbolized descent from the Umayyads.
Prior to the commencement of the Morisco revolt, Aben Humeya had been a town councilor of Granada and had been under house arrest for pulling out a dagger in the city council.
The increasing persecution of the remaining Morisco population of Granada, led to the outbreak of armed rebellion. The revolt was planned by Ferag ben Ferag, descended from the royal house of Granada and Diego Lopez Ben Aboo. They carfully ascertained the dispositons of the inhabitants of the Alpujarras, where the best stand could be made against the royal forces, solicited aid from the kings of North Africa, and persuaded the local bandits to embrace their cause.
On Christmas Eve 1568, representatives of the Crypto-muslims from Granada, from the Alpujarras, and from elsewhere clandestinely assembled at the Vale de Lecrin to acclaim Fernando de Valor as their king whom they renamed Aben Humeya and apostasized. Aben Humeya also took his full Quranic complement of wives, drawn from a number of areas, so as to help cement the political alliances on which he relied.
The insurrection led by Aben Humeya took the form of guerrilla warfare against the Castillan forces in the Alpujarra mountains. Initially numbering only about 4,000 men, the rebel forces quickly grew to about 30,000. The insurgents murdered the few Christian families and priests who lived in their village and destroyed churches and sacred images.
A prominent muslim from Albacete de Ujijar named Diego Alguazir was said to have harbored resentment against Aben Humeya for having forcibly abducted a widowed cousin and making her his mistress, when with her social status he should have taken her as his wife. Alguazir eventually married her in Tetuan six years later. In order to avenge his cousin's honor, Alguazir began plotting Humeya's downfall.
Aben Humeya had also long distrusted his Turkish and African allies, whom he removed from his camp to the frontier in Almeria and placed under the command of his cousin, Aben Aboo.
Alguazir began to play on the tensions that Humeya had reportedly had with the Turkish contingent of his army for quite some time. He went to the Turks and claimed that "he had supplied Hashish to Aben Humeya in order that it be given to the Turkish captains so that they would be sedated and later, killed that night". The Turks refused the offer, explaining that the Turkish Caliphate had sent them "not to become kings but to assist the king of the Andalusians."
The Captains suggested that the best course was, after securing approval from Algiers, to put power in the hands of a local man of noble descent in whom one might have confidence, someone who would serve the interests of the Muslims.
In October 20, 1569, he was strangled to death in a coup engineered by the Turkish military experts and Aben Aboo was proclaimed as Chief of the Moriscos under the name Mulley Abdalla. Various Christian sources including the Christian historian, Marmol state that with his dying breath Aben Humeya declared himself a Christian and said that what he had done was in the prosecution of a family feud. His successor, Aben Aboo, was also eventually killed by his own men.
The deaths of Aben Humeya and Aben Aboo coupled with the arrival of 20,000 soldiers under the command of Don Juan of Austria, Philip's illegitimate half-brother, to quash the rebellion, brought an end to over two years of vicious guerilla warfare in the Alpujarras. Almost the entire population of the Alpujarras was then deported to Castille and western Andalusia and some 270 villages and hamlets were repopulated with settlers brought in from Northern Spain. The remaining villages were abandoned. This led to the destruction of the silk industry over the course of several centuries.
