Royal Edict Issued to Hyesim
It is written in black and white on a scroll, made of seven pieces of red, yellow and white papers, and it measures 3.6 cm wide by 33 cm long (1.4 inches by 13 inches).

Buddhism is thought to have been introduced to Korea around the year 372. But only during the Unified Silla and Goryeo eras - when Buddhism was legally declared the state religion - that the religion really flourished.
Today, Buddhism is Korea’s No. 2 religion, slightly behind Protestantism, according to a recent survey. The last time such a survey was conducted, in 2004, Buddhists outnumbered Protestants by 5.1 percentage points.
