Shimun XIII Dinkha

Mar Shimun XIII Dinkha was Patriarch of the Chaldean Catholic Church carrying the title Patriarch of Babylon between 1662 and 1692. He was in communion with Rome and resided in Khosrau-Abad near Salmas. He was the last in the hereditary Shimun line of Patriarchs in the Chaldean Catholic Church and, like his predecessors Shimun X Eliyah (1600–1638), Shimun XI Eshuyow (1638–1656) and Shimun XII Yoalaha (1656–1662), was not officially recognized by Rome since the Catholic church does not approve of hereditary patriarchates.

In 1692, Patriarch Shimun XIII moved the seat of his patriarchate to Qochanis (modern-day Konak, Hakkari), broke communion with Rome and became Patriarch of the Church of the East. He continued the Shimun hereditary line of Patriarchs in the Church of the East, a tradition that continued until the death of Patriarch Shimun XXI Eshai in 1975.

Patriarch Shimun Dinkha died around 1700 AD and was succeeded in the Church of the East by Shemʿon XIV Shlemon.
