Ignatius Yunan was the Patriarch of Antioch and head of the Syriac Orthodox Church from 1817 until 1818 when he resigned from the Holy See and went to live in the Monastery of Mor Elias until his death in 1823.
[1] He was known of his piety and continues fasting [2] but that didn’t help him in managing the affairs of the Patriarchate and alienated some faithful in the city of Mardin.
[1] When he saw that, he decided to abdicate the See of Antioch and went to live in the Monastery of MOR Elias in Tur-Abdin until he died in 1823.
[1] There is no information if Ignatius Yunan ordained any Metropolitan in his short time as a patriarch.
However, one of the future patriarchs Ignatius Jacob II studied under him after he went to live in the Monastery of MOR Elias in Tur-Abdin.
