1. Current Status  


The Republic of Korea guarantees freedom of religion under Article 20 of its Constitution and does not recognize any state religion. According to Statistics Korea (https://kosis.kr/search/search.do), approximately 44% of South Korea's population identifies as religious. Among them, Protestants make up about 19%, Buddhists about 17%, and Catholics around 7%. In addition, other religions, including Won Buddhism, Confucianism, Cheondoism, Daejongism, and shamanism coexist in contemporary Korean religious culture.

2. Historical Background


Korean Shamanism dates back to prehistoric times, long before the introduction of Buddhism and Confucianism from China. It centers on influencing the spiritual world to bring prosperity, healing, protection, and guidance to individuals or communities. This is often practiced through Gut rituals performed by shamans known as Mudang.


Buddhism was introduced to Korea in the 4th century and became a dominant cultural and spiritual force, especially during the state-sponsored promotion of Buddhism from the Three Kingdoms period (3th century–668) to the Goryeo Dynasty (918–1392). As a result, a significant portion of Korea's cultural heritage consists of Buddhist architecture, art, and sculptures—such as Seokguram Grotto and Bulguksa Temple.


Confucianism began to significantly influence politics during the Goryeo Dynasty (918–1392) and became the dominant ideology during the Joseon Dynasty (1392–1910), when it was officially recognized as the state religion. It emphasizes propriety, filial piety, and loyalty, values deeply connected to the culture of patriarchy, collectivism, and hierarchical order. Confucianism profoundly shaped ancestral rites and traditional lifecycle rituals, known as Gwanhonsangje.


Catholicism and Protestantism were introduced in earnest by Western missionaries in the late 18th and 19th centuries, during the late Joseon period. During the industrialization period (1960s–1980s), the Christian population, particularly Protestants, surged dramatically and exerted a powerful influence on modern Korea's politics and economy.


During the Japanese colonial period (1910–1945), Korean ethnic religions—such as Won Buddhism, Cheondoism, and Daejongism—gained traction among the population and played leading roles in the independence movement. These religions are characterized by their mission to achieve national salvation and their elevation of patriotism to a religious ideal.


Islam was first introduced to Korea as early as the 8th century but nearly disappeared during the Joseon era. It was reintroduced during the Korean War in the 1950s by Turkish soldiers. The recent influx of Muslim immigrants has contributed to the growth of the halal food industry, fostering an understanding of Islamic dietary laws among the broader Korean public.
