Yi Ja-gyeom

Yi Ja-gyeom (died 19 January 1127[1]) of the Incheon Yi clan, was a Korean politician, soldier, regent, and poet in the middle Goryeo dynasty. In 1122, he became the Duke Hanyang (한양공, 漢陽公) and the Duke of Joseon State (조선국공, 朝鮮國公) two years later. As the full maternal grandfather of Injong of Goryeo, Yi became the young king's regent after his father's death and even purged those who were trying to usurp the throne. He gained more power upon marrying his two daughters to Injong,[2] but was eventually eliminated by Injong after he tried to poison the king.

In 1126, he started a rebellion to purged his opponents and seized his own power, but was removed by Cheok Jun-gyeong (척준경), Yi's previous ally but whom now sided with Injong. During his exile in Jeollanam-do, Yi ate a dried fish and named it "Yeonggwang Gulbi" (영광 굴비) after "Yeonggwang" was his exile location and "Gulbi" was came from one of his word, "I Won't Give Up" (뜻을 굽히지 않겠다). Although exiled peoples are mostly forgotten by the monarch, Injong still respected Yi as his maternal grandfather and his guardian when he was too young, thus he gave Yi and his wife, Lady Choe some tributes from the palace and deeply commemorated them, even gave all of their sons "600 grains" (600석 곡식) each.
