Moreover, she was later honored as Grand Queen Dowager Insu (인수대왕대비) during the reign of her grandson Yi Yung, Prince Yeonsan.

She is mostly known for her proficiency in Chinese Classics, Confucianism and Buddhism as well, and for her involvement in the political affairs of her time,[1] from the accession of Grand Prince Suyang to the throne to the reign of Yeonsangun.

After the 1453 coup, aka Gyeyu Jeongnan (계유정난), Grand Prince Suyang became Chief State Councilor (영의정) and Minister of Personnel (이조 판서) as well.

[6] At the death of Sejo, the second son of the late King accessed to the throne and the influence of Lady Han waned.

Jaseong, as grand queen dowager and the most senior elder in the royal family, solved this problem with her statement that Insu had been entrusted with the task of protecting Yejong by the late King Sejo, implying her seniority above both the late Yejong and Queen Dowager Inhye.

So Insu was honored as queen dowager in 1474 and had higher rank than Inhye, and her late husband received temple name Deokjong (덕종; 德宗), acknowledging them as Seongjong's formally recognized parents.

With the death of Seongjong and the accession of her grandson Yeonsangun, she became the Grand Queen Dowager Insu (인수대왕대비) and gathered even more power.

At the end, this led to a brutal clash and she died in 1504 after an altercation with Yeonsangun who found out about the cause of his birth mother’s death.
