Queen Insu

Queen Sohye (Korean: 소혜왕후; Hanja: 昭惠王后; 16 October 1437 – 21 May 1504), of the Cheongju Han clan, commonly known as Queen Insu, was the wife of Crown Prince Uigyeong (posthumously King Deokjong). Though her husband never became king during his lifetime, she was nevertheless elevated to the position of queen following the accession to the throne of her second son, King Seongjong, in 1470. She was then styled as Queen Dowager Insu from 1475 until King Seongjong's death, and as Grand Queen Dowager Insu during the reign of her tyrannical grandson, Yeonsangun. Queen Insu is remembered for her proficiency in Chinese classics, Confucianism and Buddhism, as well as for her involvement in political affairs, which spanned from the accession of her father-in-law, Grand Prince Suyang, until her death during the reign of her grandson, Yeonsangun. In 1475, she wrote Naehun, widely regarded as the first book authored by a woman in Korea.
