fend the invaders due to Yuan's forceful disarmament, Chungryeol was said to spoil himself and his followers with extravagant royal banquets; maintaining an indifferent stance towards the invasion. King Chungnyeol, who neglected the situation and wasted national treasury consistently with an irresponsible demeanor, was even criticized by the Mongolian general Naimandai who came to assist the Korean forces fighting Kadaan's rebels. Korean defenses proved effective later on upon achieving decisive victories at Chi'ak Fortress (Korean: 치악성, Hanja: 雉岳城, Modern-day Wonju) and Yeongi (Korean: 연기, Hanja: 燕岐, Modern-day Sejong City), later strengthened by the assistance of the ten-thousand Yuan troops led by Naimandai. Nonetheless, many Korean locals were killed by the Kadaan-led rebels who were scavenging for food and supplies as a result. Deprived of Power After royal authority was strengthened by utilizing the powers of close aides, Chungnyeong continued to spoil himself by enjoying feasts and falconry. Then, with the returning of Crown Prince (King Chungseon) and Princess Gyeguk from Mongolia in 1297, he expressed his intention to cede the throne to his son Jang (King Chungseon) in 1298 and eventually stepped down. However, political strife stemming from opposition towards Chungseon's reform policy and the royal family's adulterous affairs led to political factions plotting between each other. He was eventually reinstated after eight months. In 1306, King Chungnyeol plotted against his son, the Crown Prince, with aims of preventing his reinstatement by having them divorced since Goryeo kings at the time could only rise to power under the condition of marrying a Mongolian Princess. However, the Crown Prince's quick response to the king's plot along with the abscession of Külüg Khan, the brother of the Prince's wife, neutralized such attempts made by Chungnyeong. The Crown Prince was eventually crowned in 1307 as King Chungseon, with Chungnyeol having been detained at a temple in Dadu. He eventually returned to Goryeo with all political power deprived. Death After a crushing defeat in the political dispute with his own son and returning to Goryeo, King Chungnyeol lost his will to politics and died at the age of 73 in Shinhyo Temple in July 1308, spending his final days hunting and drinking. He was said to have deep regrets regarding how the nation was left devastated and the political dispute causing discord between family members of the Royal House.
