Surnamed The Terrible, grandson of the preceding, assumed the sovereignty at 14, had himself crowned in 1545, and took the title of Czar; his first great ambition was to destroy the Tartar power, which he did at Kasan and Astrakhan, receiving homage thereafter from almost all the Tartar chiefs; on the death of his wife in 1563 he lost all self-restraint, and by the ferocity of his wars provoked hostility which the Pope, who had been appealed to, interposed to appease; in a fit of passion he killed his eldest son, whom he loved, remorse for which embittered his last days and hastened his end (1530-1584).
