Esayi Hasan-Jalalyan

Esayi Hasan-Jalalyan (Եսայի Հասան-Ջալալյան), Yesai or Esayi Hasan-Jalalyants ( - d. 1728) was an Armenian historian and catholicos of Aghvank (otherwise known as Church of Caucasian Albania, effectively a part of Armenian Church at this time) from 1702 (de facto, 1701) to 1728 from Hasan-Jalalyan family.

Life
His birthdate is not known. According to Raffi, his father was Velijan III (d. 1686), melik of Khachen. He was among the Armenian nobility who convened together and sent Catholicos Jacob IV along Israel Ori to gather Western support for liberation of Christians, namely Armenians from Safavid Empire.

Catholicosate
After deaths of Simeon IV (1675-1701) and Eremia II (Esayi's uncle, 1676-1700), who were rival catholicoses of Aghvank, Esayi applied to Shah Sultan Husayn of Safavids in October–November of 1701 to be recognized as new catholicos and paid 50 gold. He was later consecrated as catholicos by Nahabed I of Armenia in 1702. Esayi used opportunity to broaden his influence to Russia during 10-month vacancy in Armenian See. However, another bishop, namely Nerses V (1706-1736) declared his own catholicosate in Yerits Mankants Monastery. Although in 1707, Alexander I of Julfa supported Esayi against Nerses, the latter kept claiming legitimacy. He went to Russia in 1711 with Israel Ori to meet Peter the Great, however Israel died in Astrakhan and Esayi went back to Karabakh. Alexander's successor Asdvadzadur of Armenia later took certain privileges of Esayi back to Armenian church in 1716, but returned these rights in 1719.

Esayi was strongly pro-Russian and sent two letters - first on 23 September 1718 and second on 1 April 1721 - to Peter, requesting his assistance. He later went to visit Kartli king Vakhtang VI on 28 May 1722 and joined his army in his eventually unsuccessful rebellion against Safavids with promised aid from Peter the Great. He managed to gather 10.000 troops from different meliks of Karabakh on 18 September 1722, However, Vakhtang, abandoned by his Russian allies, returned to Tbilisi in November 1722. Against the wishes of Asdvadzadur, he resisted to Ahmed III, when Ottoman armies invaded Azerbaijan using the opportunity in 1722 and supported Davit Bek. However after capture of Revan by Ottomans on 28 September 1724 and following Treaty of Constantinople, when Russians recognized Ottoman ownership of Georgia and Armenia, Esayi had to submit alongside other feudals in the region. In July 1726, he accompanied by Karabakh beys, meliks and landlords, went to Barda to visit Sari Mustafa Pasha (son of Gazi Hüseyin Pasha and future son-in-law of the Sultan) for negotiations.

According to some sources, he was accused of betrayal by other Armenian nobles and forced to commit suicide in 1728.

Work
He collected inscriptions of Karabakh monasteries (Dadivank, Katarovank, Goshavank, Gandzasar, etc.), different manuscripts of Gospels. He is most famous for his incomplete work named "A brief history of Aghvank region", which is a description of the events of his time and reaches up to 1723. The book was first published in Shusha by Baghdasar Hasan-Jalalyan in 1836, later in French (1876) by Marie-Félicité Brosset, Armenian (1868), Georgian (1971), Azerbaijani (1992).
