The traditional culture of Korea refers to the shared cultural heritage of the Korean Peninsula originating from the early Korean nomadic tribes to the extensive influence of 9,000 years of ancient Chinese culture to modern times. Since the mid-20th century, the peninsula has been split politically between North and South Korea, resulting in a number of cultural differences.[1][2][3][4] Before Joseon Dynasty, the practice of Korean shamanism was deeply rooted in the Korean culture.[5]
