The Silla Kingdom, also known as the Kingdom of Silla, was one of the three major kingdoms of ancient Korea. It emerged on the Korean Peninsula during the Three Kingdoms period, which lasted from the 1st century BCE to the 7th century CE. The Silla Kingdom is known for its unification of the Korean Peninsula and its contributions to Korean culture and history. Here are key points about the Silla Kingdom:
