Mar Nicholas I Zaya was the patriarch of the Chaldean Catholic Church from 1839 to 1847. He succeeded Yohannan VIII Hormizd, the last of the Mosul patriarchs who traced their descent from Eliya VI (1558–1591), and his elevation ended four centuries of hereditary succession in the Eliya line. After Zayʿa's accession the Vatican attempted to reform abuses within the Chaldean Church, but its interference was strenuously resisted by several Chaldean bishops. As a result, Zayʿa's short reign was plagued by one crisis after another. In 1846, after the Vatican conspicuously failed to support him against his recalcitrant bishops, he resigned the patriarchate and retired to his native town of Khosrowa, where he died in 1855. He was succeeded by Joseph VI Audo, one of his most determined opponents.
Yohannan VIII Hormizd (1760–1838) was the last hereditary patriarch of the Eliya line of the Church of the East and the first patriarch of a united Chaldean Church.

In 1783, he was recognized by the Vatican as patriarchal administrator and archbishop of Mosul. His career as patriarchal administrator was controversial, and was marked by a series of conflicts with his own bishops and also with the Vatican. Suspended from his functions in 1812 and again in 1818, he was reinstated by the Vatican in 1828. In 1830, following the death of the Amid patriarchal administrator Augustine Hindi, he was recognised by the Vatican as patriarch of Babylon of the Chaldeans and the Mosul and Amid patriarchates were united under his leadership. This event marked the birth of the since unbroken patriarchal line of the Chaldean Catholic Church. Yohannan Hormizd died in 1838 and his successor Nicholas I Zayʿa was chosen by the Vatican, ending the centuries-old practice of hereditary succession.
