John IV of Armenia
# John IV of Armenia

John IV (Armenian: Հովհաննես Դ Ավայեցի) was the Catholicos of the Armenian Apostolic Church in 833–855 when the country was under Abbasid overlordship.

In 841, he was deposed by the episcopal synod through the machinations of Bagrat II Bagratuni, but he was promptly re-installed in his see by Bagrat's brother Smbat with the assistance of the other princes.

It was during John IV's tenure that the Tondrakians first emerged.
