Unified Silla (676-935) is the period when Silla occupied from Daedong River to the south of Wonsan bay and formed a nation-state after the unification of the three countries. The capital city, Gyeongju took the shape of a castle town by organizing and maintaining towns. As it

actively engaged in exchanges with Southwest Asia, Tang Dynasty of China, Japan, etc, it grew into an international city. The advanced culture of the capital city gradually diffused to the local areas. Buddhism during the era of Unified Silla brought about major changes in

society and culture. As cremation became popular, burial urns were widely used. The leading Buddhist architecture such as Bulguksa (temple) and Seokgulam were established. Unified Silla integrated the cultures of Goguryeo and Baekje to form the basis for a national

culture.
