Arghun Aqa: Mongol bureaucrat in Iran, an article by George Lane in Academia.edu

[Appointed governor of Khurāsān in 1242 by the then regent of the Mongol Empire, Töregene Khātun Töregene Khatun Régente 1241-1246. Arghun Aqa retained this office throughout thesubsequent reigns of Güyük Khan (r. 1247- 8), and the latter's successor, Möngke (r. 1251 -1259), during which time his mandate was extended to include the whole of Iran. Under Möngke's rule, Arghun Aqa served at the head of one of the three regional secretariats responsible for administering the sedentary populations of the Mongol Empire and was entrusted with carrying out a census of Iran as well as implementing a new tax system over the territories under his jurisdiction. The appointment of Möngke's brother, Hülegü Khan Hulagu Borjigin dynasty, as the first Īlkhān of Iran naturally resulted in a diminution of Arghun Aqa‟s powers. Nevertheless, he retained the governorship of Khurāsān under the new regime and in 663/1265 Hülegü‟s successor, Abaqa (r. 663-680/1265-1282), confirmed him as "muqṭa’ - i mamālik ‟ (tax-farmer general) and „wazīr of Khurāsān,‟ titles which he held until his death in 1275.]

He had many wives, including a daughter of Yesü Möngke (https://www.geni.com/family-tree/index/6000000009781492902) , to whom he married in 1249. Another wife of his was Sürmish, who gave birth to Nawruz. He had at least 14 sons and 4 daughters.

Arghun Agha, also Arghun Aqa or Arghun the Elder (died 1278) was a Mongol noble of the Oirat clan in the 13th century. He was a governor in the Mongol-controlled area of Persia from 1243 to 1255, before the Ilkhanate was created by Hulagu.[1] Arghun Agha was in control of the four districts of eastern and central Persia, as decreed by the great khan Möngke Khan. When he was young, his father sold his son Arghun to Ilugei of the Jalayir, tutor of Ogedei Khan. During his years with the Ogedeyid family, he gained reputation among the members of the Royal blood because he was well educated. Arghun started his career as court official during the reign of the Qaghan Ogedei. Later on, the latter's consort, Toregene Khatun, appointed him civil governor in Transoxiana in c.1242. Ascelin of Lombardia might have met him while he was at the court of Baiju in c.1247. In 1259-61 he directed punitive operations against rebels in Georgia, and then was sent to Khorasan to fight the Golden Horde. He is described as faithful servant of the Qaghan in Persian sources while the Georgian and Armenian sources say he was cruel and violent overseer. However, one Georgian chronicle mentions he was a friend of equity, trustful in his language, a deep thinker, and profound in counsel. It also says Arghun conducted the empire-wide census in Russia, Arctic, Alania, Pontic steppe, Georgia, Armenia, and Anatolia.
Arghun had many political enemies at the headquarters, so he had to often visit the ordo (palace) of the Qaghan in Mongolia to prove his loyalty. Although, Möngke appointed him to his former position after his accession in 1252, the Emperor summoned Arghun to answer a charge of treason. The Armenian noble, Sempad Orpelian, justified Arghun completely and charged his enemy a Kharazmi lieutenant with being the real offender. Arghun was released and they returned together. Arghun made a census in Persia in accordance with the decree of Mongke in 1254. Arghun's son Nowruz was a powerful Mongol emir in his own right, an early convert to Islam, and persuaded Ghazan to convert in 1295 when he took the throne

--- ... [Much less is known of Arghun Aqa's son, Amīr Nawrūz, who first appears in the sources as a senior commander of the Qaraunas, whose pastures lay on the banks of the Oxus River. In 683/1284 Nawrūz led his troops in support of the Chinggisid prince, Arghun Oghul, who seized the throne of the Īlkhānate from his uncle, Aḥmad Tegüder, in the same year. Shortly after Arghun seized the throne, he appointed his thirteen year old son, Ghazan, as the viceroy of Khurāsān and Nawrūz was named as his "atabeg‟ (guardian) to “strive in matters of the army and the amīrate.”...] ref: https://www.academia.edu/7225166/The_Nawruz_King_The_Rebellion_of_A... article by Michael Hope - History of the Mongol Empire,Medieval Islamic History, Ilkhanate
