Yi-Tajo came to power through an anti-Buddhist movement. Yet on the whole he dealt leniently with the religion. He crippled it but did not destroy it. Through the greater part of the Yi Dynasty, however, Buddhism was at serious disadvantage. Only for a short time under the king Seijo did it have a momentary revival. He ruled from 1456 to 1468.

During this invasion some of the priests showed themselves loyal, thus Hulbert tells us:
