Ali-Agha Suleymanzadeh (Azerbaijani: Axund Əliağa Süleymanzadə) — 10th Sheikh al-Islam, akhund and the chairman of the Religious Council of the Caucasus.
Seeing Ali's deep interest in religion, his future relative Akhund Haji Mohammed wants to send him with his son Aga-Mammed to the countries of the Near East to receive spiritual education.
On the eve of returning to his homeland, Ali-agha's friend Aga-Mammed falls ill with a severe fever, and the prescribed treatment was useless.
Ali-Agha Suleymanzadeh, who had worked as akhund of the Taza Pir Mosque for almost 20 years, was elected chairman at the age of 83.
In October 1970, an All-Union Conference was organized in the capital of Uzbekistan, Tashkent on the theme "The Importance of Unity and Cooperation in the Struggle for Peace", in which he took part and delivered a speech.
