When Yun arrived back in Korea from his studies abroad, there were small groups of scholars who were beginning to call for social and political reform in Korea. One such group was the Independence club, which Yun began to participate in. Among other things, the club promoted educating the Korean people on their unique history, promoted the use of Hangeul, the Korean vernacular alphabet, and pushed for government reform. While in the Independence Club Yun called for the government to be more representative of its people and even supported the elevation of King Kojong to the title of Gwangmu Emperor. Eventually the group was met with pressure from opposing factions in the government that believed the club was gaining too much influence and so in 1899, the club disbanded.
