In 1918, Horace Horton Underwood, the third president of Yonsei (then Chosen Christian College), offered the first sociology course in Korea. Since its inception in 1972, the Yonsei Sociology Department has produced a number of graduates and sociologists who apply sociological insights and knowledge in their daily lives and contribute to society in a variety of ways. The Yonsei sociology department not only leads the field of sociology in Korea, but also provides a sociological perspective on the present and future of our changing world.
