The moment
Buddhism had reached the northern Korean kingdom of Goguryeo in 372 and Baekje soon after, but Silla's nobles held out. Korean tradition says that in 527 the court official Ichadon offered his life to end the stalemate: he was beheaded, wonders followed, and the shaken ministers gave way. King Beopheung then recognised the religion.
