Uzun Hasan
Uzun Hasan or Uzun Hassan (, ; 1423 – January 6, 1478), where "uzun" means "tall" in Oghuz Turkic, was a ruler of the Turkoman Aq Qoyunlu state, and generally considered to be its strongest ruler. Hasan ruled between 1452 and 1478, and would preside over the confederation's territorial apex, when it included parts or all of present-day Iraq, Turkey, Azerbaijan, Iran, Transcaucasia and Syria. Reign. Timur appointed Uzun Hasan's great-grandfather, Kara Yülük Osman, as a governor of Diyarbakır, with the cities of Erzincan, Mardin, Ruha (or Urfa), and Sivas. Later, Persia was divided between two Timurid  rulers, Jahan Shah of Kara Koyunlu (the Black Sheep Turkoman) and Uzun Hasan. After twenty years of fighting, Uzun Hasan eventually defeated Jahan Shah in a battle near the sanjak of Çapakçur in present-day eastern Turkey on October 30 (or November 11), 1467. Upon the defeat of the latter, another Timurid ruler, Abu Sa'id Mirza, answered Jahan Shah's son's request for aid, taking much of Jahan Shah's former land and going to war with Uzun Hasan despite the latter's offers of peace. Uzun Hasan then ambushed and captured Abu Sa'id at the Battle of Qarabagh , whereupon he was executed by Yadgar Muhammad Mirza, a rival. In 1463, the Venetian Senate, seeking allies in its war against the Ottomans, sent Lazzaro Querini as its first ambassador to Tabriz, but he was unable to persuade Uzun Hassan to attack the Ottomans. Hassan sent his own envoys to Venice in return. In 1471, Querini returned to Venice with Hazzan's ambassador Murad. The Venetian Senate voted to send another to Persia, choosing Caterino Zeno after two other men declined. Zeno, whose wife was the niece of Uzun Hassan's wife, was able to persuade Hassan to attack the  Turks. Hassan was successful at first, but there were no simultaneous attack by any of the western powers. Uzun Hasan met the Ottomans in battle near Erzincan in 1471, advanced as far as Akşehir, pillaging and destroying Tokat, and fought a battle at Tercan in 1473. He was defeated by Mehmed II at Battle of Otlukbeli in the late summer of 1473. In 1473, Giosafat Barbaro was selected as another Venetian ambassador to Persia, due to his experience in the Crimean, Muscovy, and Tartary. Although Barbaro got on well with Uzun Hassan, he was unable to persuade the ruler to  attack the Ottomans again. Shortly afterwards, Hassan's son Ogurlu Mohamed, rose in rebellion, seizing the city of Shiraz. After yet another Venetian ambassador, Ambrogio Contarini, arrived in Persia, Uzun Hassan decided that Contarini would return to Venice with a report, while Giosafat Barbaro would stay. Barbaro was the last Venetian ambassador to leave Persia, after Uzun Hassan died in 1478. While Hassan's sons fought each other for the throne, Barbaro hired an Armenian guide and escaped. According to Contarini, ambassador to Uzun Hasan's court from 1473 to 1476, "The king is of a good size, with a  thin visage and agreeable countenance, and seemed to be about seventy years old. His manners were very affable, and he conversed familiarly with every one around him; but I noticed that his hands trembled when he raised the cup to his lips." His name means "tall" and Contarini reported that he was also "very lean". Contarini also wrote, "The empire of Uzun-Hassan is very extensive, and is bounded by Turkey and Caramania, belonging to the Sultan, and which latter country extends to Aleppo. Uzun-Hassan took the kingdom of Persia from Causa, whom he put to death. The city  of Ecbatana, or Tauris, is the usual residence of Uzun-Hassan; Persepolis or Shiras ..., which is twenty-four days journey from thence, being the last city of his empire, bordering on the Zagathais, who are the sons of Buzech, sultan of the Tartars, and with whom he is continually at war. On the other side is the country of Media, which is under subjection to Sivansa, who pays a kind of yearly tribute to Uzun-Hassan. It is said that he has likewise some provinces on the other side of the Euphrates, in the neighbourhood of the Turks. The whole  country, all the way to Ispahan... is exceedingly arid, having very few trees and little water, yet it is fertile in grain and other provisions. "His eldest son, named Ogurlu Mohamed, was much spoken of when I was in Persia, as he had rebelled against his father. He had other three sons; Khalil Mirza, the elder of these was about thirty-five years old, and had the government of Shiras.Yaqub Beg, another son of Uzun-Hassan, was about fifteen, and I have forgotten the name of a third son. By one of his wives he had a son named  Masubech, or Maksud beg, whom he kept in prison, because he was detected in corresponding with his rebellious brother Ogurlu, and whom he afterwards put to death. According to the best accounts which I received from different persons, the forces of Uzun-Hassan may amount to about 50,000 cavalry, a considerable part of whom are not of much value. It has been reported by some who were present, that at one time he led an army of 40,000 Persians to battle against the Turks, for the purpose of restoring Pirameth to the sovereignty of Karamania, whence he had been expelled  by the infidels. Marriages and children. Uzun Hasan married four times: Uzun Hassan had seven sons: Despina's daughter Alam Shah Begum, also known as Halima Begi Agha and Martha, married Sheikh Haydar Safavi and became the mother of Shah Ismail I of the Safavid Empire. Legacy. Uzun Hasan translated the Quran into Oghuz Turkic. He initiated some financial and administrative reforms to weaken the separatism of the military and tribal nobility and to strengthen his vast state. The sources do not provide detailed information about Uzun Hasan's reformist activities. Although the texts of his laws has not reached  us, it is possible to judge the reforms on the basis of little information about the laws that the chroniclers called "King Hasan's Laws" or "Dasturi-Hasan Bey". Some documents related to the western territories of the Aq Qoyunlu state, which became part of the Ottoman Empire (Diyarbakir, Mardin, Urfa, etc.) are kept in the Turkish archives. These sources are important in terms of studying feudal relations in the provinces of the Aq Qoyunlu. The general nature of Uzun Hasan's reform is stated in "Tarikh al-Qiyasi": "Uzun Hasan was fair and kind. He wanted to abolish taxes  throughout the country. But the emirs did not agree with him. The Sultan then reduced the taxes by half to twenty-one dirhams ... He clarified the amount of taxes collected in the whole country. Uzun Hasan demanded that lawbreakers be severely punished. The Sultan "sent the law to every province of the State to put into effect." After the conquest of eastern Anatolia in 1517-18, and of Iraq in 1537, the Ottomans preserved the laws of Uzun Hasan ("Qānūn-nāma-ye Ḥasan Pādšāh"). It was after 1540, that the Ottoman regulations replaced the Aq Qoyunlu code. Large parts of  his tax and trade laws are recorded in Ottoman sources.
