Don Antonio Osorio de Acuña (1459 in Valladolid – 23 March 1526[1]) was a Spanish bishop of Zamora, appointed 4 January 1507,[1] during the reigns of Ferdinand II and Charles V. He filled that see in 1519, when the civil war broke out in Spain.
In the view of identifying religion with liberty, he raised a regiment of priests, whom he always conducted to battle; and though 60 years of age, he was sure to be right in the middle of the action.
By the Conde de Haro, the rebels were at length defeated; but the priests stood firm; and dreadful was the carnage which they produced among the royalists.
[2] When Toledo was besieged by the royalists, the bishop hastened to that city, not so much to assist Maria Pacheco in repelling the assailants, as to seize the vacant archbishopric.
There, in February 1526, he broke the skull of the alcalde with a brick, and was escaping, when the son of the officer discovered and secured him.
