Gregory IV, Pope
Gregory IV, Pope a native of Rome, made pope A.D. 827. By taking, in 833, the part of, the three rebellious sons of Louis le Dehbonnaire against their father, this prelate embroiled himself much with his clergy, especially those of France, who, favoring the cause of Louis, refused to receive either him or his decrees. Gregory wrote a Letter to them, which is among Agobard's Works, which shows him to be arbitrary and tyrannical, claiming obedience to him, though against the commands of their prince. There are three other Letters in Lahbbeh Concil. volume 7, and Baluze, Misceal., which evince the same spirit of grasping dominion. It was this pope who made the feast of All Saints general throughout the Western Church. He died A.D. 844. — Clarke, Succession of Sacred Lit. volume 2; Baronius, Annales, t. 14.
