Centuries after Buddhism originated in India, the Mahayana Buddhism arrived in China through the Silk Route in 1st century CE via Tibet, then to Korea peninsula in 3rd century during the Three Kingdoms Period from where it transmitted to Japan. In Korea, it was adopted as the state religion of 3 constituent polities of the Three Kingdoms Period, first by the Goguryeo (Gaya) in 372 CE, by the Silla in 528 CE, and by the Baekje in 552 CE. Buddhism was introduced to Silla in 528. Silla had been exposed to the religion for over a century during which the faith had certainly made inroads into the native populace. The Buddhist monk Ado introduced Silla to Buddhism when he arrived to proselytize in the mid 5th century. The Samguk yusa and Samguk sagi record following 3 monks among the first to bring Buddhist teaching, or Dharma, to Korea: Malananta (late 4th century) - an Indian Buddhist monk who brought Buddhism to King Baekje of Baekje in the southern Korean peninsula in 384, Sundo - a Chinese Buddhist monk who brought Buddhism to Goguryeo in northern Korea in 372, and Ado - a Buddhist monk who brought Buddhism to Silla in central Korea. However, according to legend, the Silla monarchy was convinced to adopt the faith by the martyrdom of the Silla court noble Ichadon, who was executed for his Buddhist faith by the Silla king in 527 only to have his blood flow the color of milk.
