Chunam Park In-ho(1855-1940), the fourth generation leader of Donghak Cheondogyo, was a representative national activist and enlightenment thinker who inherited the traditions of Choi Je-woo, Choi Si-hyeong, and Son Byeong-hee, but was also active in the new culture movement with an open attitude. He showed extraordinary historical awareness by practicing Inaecheon, the fundamental idea of Donghak Cheondogyo, as a national, cultural, and enlightenment movement. This study sought to reveal Chunam Park In-ho’s Donghak Thought and historical awareness through his life and spiritual culture movement. The content of the study was to summarize his life and activities and present the characteristics of educational and cultural ideas, such as the norm of “merit and virtue” (公德心) and the idea of education as “gonggi” (公器). The result of the study was that his Donghak thought and historical awareness should be newly evaluated as a Korean spiritual culture that can contribute to communicating with various cultures and spreading the spirit of community and coexistence while maintaining Korean self-esteem even in today’s trend of globalization.
