[2] Michael Panaretos wrote that in June 1348, Ahi Ayna led a joint attack against the Empire of Trebizond together with Tur Ali Beg of Aq Qoyunlu Turkmens and Muhammad Rikabdar, Emir of Bayburt.
[4] An Armenian colophon of 1355 mentions that Ahi Ayna was attacked by "Khochay Yali," likely Khoja Latif of Bayburt.
[6] On 6 August 1361, Ahi Ayna continued his expedition in the region of Lazica, i.e. eastern territories of the Empire of Trebizond.
[10] Pir Husayn, who was originally the ruler of Karahisar, arrived in Erzincan on 8 June 1362 and succeeded Ahi Ayna Beg.
He "gained independence" on 10 July,[11] having clashed with emirs opposing his rule, who eventually fled to Bayburt and Tercan.
[15] Mutahharten initially faced defeat in a bloody battle and retreated but still resisted coming under Eretnid rule.
[17] Kadi Burhan al-Din's (r. 1381–98) rise to power as the regent of Ali's successor Muhammad II Chelebi (r. 1380–81), and his aim at re-imposing authority over the region, prompted Mutahharten to form alliances with Burhan al-Din's rivals and other claimants to the Eretnid throne, such as Shadgeldi, Emir of Amasya (r. 1359–60/1, 1361/2–81).
[18] Mutahharten sent an embassy to Burhan al-Din, demanding that he return the throne to Ali's son, Muhammad II Chelebi, who was too young to rule.
Although Kadi Burhan al-Din released his embassy, he sent Shadgeldi's head to Erzincan in 1381 as a warning after having defeated him on the battlefield.
[21] After having dealt with his rivals in the northern region around Amasya, Tokat, and Osmancık until spring 1383, Burhan al-Din focused on his struggle east against Mutahharten.
[24] In late 1386, Timur (r. 1370–1405), a Turco-Mongol warlord who attempted to invoke the legacy of Genghis Khan, invaded west Iran and was planning his invasion of the Armenian highlands from his military camp in Karabakh.
Although Mutahharten halted his campaigns in Anatolia during this time, Timur's presence was favored by him and other enemies of Burhan al-Din.
[26] When Timur's focus shifted away from the region, Mutahharten used the Qara Qoyunlu Turkomans who took refuge in his territory in an expedition in Burhan al-Din's lands, taking advantage of Burhan al-Din's absence as he was dealing with the local Turkoman principalities to the north.
[27] Mutahharten broke the alliance with the Aq Qoyunlu upon the death of Qutlugh (r. 1362–89) and the succession of his son Ahmed (r. 1389–1403).
He stationed his army on the right bank of Murat River near the town of Gulushkerd, confronting the Aq Qoyunlu forces on the opposite side.
[34] Mutahharten was ultimately released and restored as the ruler when Qara Yusuf, who had been given control of the place, did not fare well with the locals.
Sati ibn al-Hasan, a well-respected lord and history-writer from Erzincan, is thought to have sourced the paper from Damascus, paying 6000 dirhams, for his work titled Tarikh-i Chingiz Khan (lit.
