John of Austria was quite popular in Spain, seeing as he was a decorated military figure and the king, his half-brother, was not even able to take care of his own self. He ousted Mariana, who had been serving as queen regent, and in 1677, initiated a coup in which he obtained the throne from Charles. He died two years later; the rumor was that he had been poisoned.
