In Korea, Su-un, founder of the Donghak religious sect, is executed for heresy at Daegu

In what is present-day South Korea, Su-un, the founder of the Donghak religious movement, had been arrested for sedition in late 1863, largely because his teachings of the "Eastern Way" resisted non-Korean influences and help instigate several peasant revolts.  He was tried for heresy ten days earlier at Daegu and found guilty.  He was beheaded, his works ordered destroyed, and his followers scattered and persecuted.  (By John Osborne)
