1882 crisis

In 1882, the Korean Peninsula experienced a severe drought which led to food shortages, causing much hardship and discord among the population. Korea was on the verge of bankruptcy, even falling months behind on military pay, causing deep resentment among the soldiers. There was also resentment towards the Pyŏlgigun on the part of the soldiers of the regular Korean army, as the formation was better equipped and treated. Additionally, more than 1000 soldiers had been discharged in the process of overhauling the army; most of them were either old or disabled, and the rest had not been given their pay in rice for thirteen months.

In June of that year, King Gojong, being informed of the situation, ordered that a month's allowance of rice be given to the soldiers. He directed Min Gyeom-ho, the overseer of government finances and Queen Min's nephew, to handle the matter. Min in turn handed the matter over to his steward who sold the good rice he had been given and used the money to buy millet which he mixed with sand and bran. As a result, the rice became rotten and inedible. The distribution of the alleged rice infuriated the soldiers. On July 23, a military mutiny and riot broke out in Seoul. Enraged soldiers headed for the residence of Min Gyeom-ho, who they had suspected of having swindled them out of their rice. Min, on hearing word of the revolt, ordered the police to arrest some of the ringleaders and announced that they would be executed the next morning. He had assumed that this would serve as a warning to the other agitators. However, after learning what had transpired, the rioters broke into Min's house to take vengeance; as he was not at his residence the rioters vented their frustrations by destroying his furniture and other possessions.

The rioters then moved on to an armory from which they stole weapons and ammunition, and then headed for the prison. After overpowering the guards, they released not only the men who had been arrested that day by Min Gyeom-ho but also many political prisoners as well. Min then summoned the army to quell the rebellion but it had become too late to suppress the mutiny. The original body of mutineers had been swelled by the poor and disaffected citizenry of the city; as a result the revolt had assumed major proportions. The rioters now turned their attention to the Japanese. One group headed to Lieutenant Horimoto's quarters and killed him. Another group, some 3,000 strong, headed for the Japanese legation, where Hanabusa Yoshitada the minister to Korea and twenty seven members of the legation resided. The mob surrounded the legation shouting its intention of killing all the Japanese inside. Hanabusa gave orders to burn the legation and important documents were set on fire. As the flames quickly spread, the members of the legation escaped through a rear gate, where they fled to the harbor and boarded a boat which took them down the Han River to Chemulpo. Taking refuge with the Incheon commandant, they were again forced to flee after word arrived of the events in Seoul and the attitude of their hosts changed. They escaped to the harbor during heavy rain and were pursued by Korean soldiers. Six Japanese were killed, while another five were seriously wounded. The survivors carrying the wounded then boarded a small boat and headed for the open sea where three days later they were rescued by a British survey ship, HMS Flying Fish, which took them to Nagasaki. The following day, after the attack on the Japanese legation, the rioters forced their way into the royal palace where they found and killed Min Gyeom-ho, as well as a dozen other high-ranking officers. They also searched for Queen Min. The queen narrowly escaped, however, dressed as an ordinary lady of the court and was carried on the back of a faithful guard who claimed she was his sister. The Daewongun used the incident to reassert his power.

The Chinese then deployed about 4,500 troops to Korea, under General Wu Changqing, which effectively regained control and quelled the rebellion. In response, the Japanese also sent four warships and a battalion of troops to Seoul to safeguard Japanese interests and demand reparations. However, tensions subsided with the Treaty of Chemulpo, signed on the evening of August 30, 1882. The agreement specified that the Korean conspirators would be punished and ¥ 50,000 would be paid to the families of slain Japanese. The Japanese government would also receive ¥500,000, a formal apology, and permission to station troops at their diplomatic legation in Seoul. In the aftermath of rebellion, the Daewongun was accused of fomenting the rebellion and its violence, and was arrested by the Chinese and taken to Tianjin. He was later carried off to a town about sixty miles southwest of Beijing, where for three years he was confined to one room and kept under strict surveillance.
