History: The Almohads, who took over from the Almoravids in ruling 12th century Southern Iberia, were a feared force in the entire Muslim world for their ability to maintain control over territories in mainland Europe - no other Islamic power has been able to do so since the Umayyads whom initially conquered the peninsula in the 8th century. The Christian kingdoms of the north were squabbling between themselves, so they weren't yet united to push back the Mohammedan threat. On July 18, 1195, they scored a decisive victory against the Castilians at the Battle of Alarcos, where King Alfonso VIII was badly defeated. The Andalusian melting pot, already a blend of Romance and Semitic heritage, was enhanced by the new Turkic element. Hundreds if not thousands of Oghuz Turkic mercenaries served on the winning side, and in turn were allowed by the Caliph to settle in Iberia alongside the Muwallads and Mozarabs. In a twist of irony, after the Caliph died in February 1199, the Turks turned against their North African overlords, instigating an eight year-long rebellion which culminated in the independence of the Khanate of Girnata in 1207, ruled by the Hasanzadids. The new Turkic ruling class inherited the old Moorish institutions, and continued the utilization of Sub-Saharan African slave labor and de facto discrimination against infidels. Europe was shocked that a new Turkic state was established at the far western end of the continent, when most of the Turkic incursions had been coming from the east. New and unexpected raids from the Girnatans along the Mediterranean trafficked slaves from France, Italy, and even as far away as the Balkans. When the Mamluks, who were on good terms with the Girnatans, took over Egypt later on in the 13th century, many Kipchak Turks and Circassians were resettled on the peninsula. There are records which proved that even Persians and Indians immigrated to Al-Andalus during the Girnatan Golden Age. The khans also introduced the Central Asian yogurt drink to Iberia, which evolved into the contemporary granadagua, or "water of Granada", a popular drink in the Hispanosphere. Loads of Turkic loanwords entered the Spanish language. Ultimately, the immense greed of the khans overextended Girnata's resources, and so Portugal, Castile, and Aragon eventually succeeded in reducing it to a rump state by 1523 - but an ultimatum issued by the Ottoman Sultan all the way on the other side of Europe demanded that the Iberian monarchs maintain Girnata's existence. And so, the recently unified Spain merely avoided war by acquiescing to the orders of the rapidly expanding Ottoman Empire, which temporarily soothed Spanish-Ottoman relations: Girnata would become an autonomous self-governing monarchy within the Spanish feudal system, but most of its external affairs would be dictated by Madrid. Because there was no Spanish Inquisition in this timeline (most of the remaining Jewish and Muslim populations converted to Christianity optionally instead of forcefully), the Sephardic Jews and Girnatans worked alongside the conquistadors in exploring the New World. The Girnatans use their excellent equestrian skills, inherited from their steppe-roaming ancestors, to conquer vast swaths of land for the Spanish crown. Girnatans were viewed as equals to Spaniards in the casta system, so they would always be classified as peninsulares or criollos. Of course, they too mixed with the Amerindians and Sub-Saharan Africans, contributing their DNA to the modern mestizo genepools. For the most part, they were seen as a positive influence on the Spanish Empire, and would always be trusted in advancing Spanish interests. At least, they were, until the last Khan of Girnata, Abdultemur, realized that so many of his fellow coethnics were embracing Spanish culture and Catholicism, abandoning their Muslim Turkic roots. He petitions the Spanish King to end what he sees as the unjust occupation of Girnata, and restore full sovereignty to the khanate, but the King refuses. And so a failed Ottoman-backed mutiny against the Spanish government, supported by the other Catholic powers of Europe, was the final nail in the coffin to 439 years of Girnata's existence in 1646, and in turn ending 935 years of the Reconquista, truly wiping the final Islamic stronghold in Iberia off the map. Over the next few centuries, the remaining Girnatans who weren't already Christianized or sought refuge in the Ottoman Empire shook off their old Islamic faith. Spain also experienced massive internal migrations during these centuries, where Girnatans were encouraged to migrate to other parts of the country, only to be replaced by other voluntarily moved Spanish ethnicities in their own homeland. 19th century overpopulation in Spain brought about by industrialization led to a transatlantic immigration wave. The Girnatan nation underwent a spiritual awakening in the 20th century, and in the process of rediscovering their Turkic past, frantically reached out to other Turkic peoples such as Gagauzes, Anatolian Turks, Azerbaijanis, and Crimean Tatars. Today, the Girnatans proudly see themselves as Turks, and consider the Turks of Turkey and Azerbaijan to be their closest brothers. Their calls for independence from Spain are even stronger than those of the Catalans, Basques, or Galicians. Yet they still actively participate in Spanish sports, music, politics, and entertainment, with many Girnatan celebrities such as Francisco Arslanez and Martino Sultanez being hailed as international icons. As a people, the Girnatans bridge the Ibero-American and Balkano-Turkic worlds, and they certainly have a turbulent but proud history!
