In 1617, Yun Hyu was born in
Gyeongju, the son of Gyeongju magistrate () Yun Hyo-jŏn (), of the Namwon Yun clan, and his wife Lady Kim, of the Gyeongju Kim clan. Yun's family was affiliated with the Lesser Northerners faction. His childhood name was Kaeng, given by his father's friend, Chŏng Han-kang (). At age 19, he married Lady Kwŏn. In 1636, during the
Qing invasion of Joseon, Yun went to
Songnisan, where he encountered
Song Si-yŏl for the first time. After hearing of
King Injo's capitulation to the Manchus, Yun vowed to not take the
gwageo. He moved to
Gongju,
Chungcheong Province and became a private scholar. He maintained friendships with prominent
Easterner figures, such as
Song Si-yŏl,
Song Chun-gil, and Yu Kye (). In 1674, he became involved again in a second round of the controversy, this time over the death of
Queen Inseon. In 1680, Yun was expelled and exiled to Gapsan (). That year, he was ordered to commit suicide by
King Sukjong, after a long public debate with
Song Si-yŏl. == Works ==
