|Revised Romanization||Imo gullan|
A variety of causes for this brief disturbance have been put forward. In part, some explain the flare-up of violence by pointing to provocative policies and conduct by Japanese military advisors who had been in Korea since 1881.
According to other sources, the revolt broke out in part because of Emperor Gojong's support for reform and modernization. The revolt was also explained in part as a reaction to Gojong's support for Japanese military advisors. Some sources credit rumor as the spark which ignited violence. Some were worried by the prospect of incorporating Japanese officers in a new army structure.
The disturbance is sometimes characterized as the "Imo Mutiny" (Imo kullan), and its cause is attributed to a dispute about unpaid wages. It has also been called the "Soldier's riot"; and the unplanned flare-up of violence is said to have been a reaction to finding sand and bad rice in soldiers' rations.
Dissatisfaction with the Korean government was the initial focus of the violence. Some government officials were killed by the rioters. Homes of high government ministers were destroyed and Changdeok Palace was occupied by soldiers. The rioting general population of Seoul swelled the ranks of the dissatisfied army units.
Hanabusa Yoshitada, the Japanese minister to Korea and his aides were forced to flee the legation. They escaped to the sea in a small boat and were rescued by a British ship, the Flying Fish. During the day of rioting, a number of Japanese were killed, including Horimoto Reijo.
The Chinese dispatched troops; and three warships were sent to Seoul.
In the aftermath of rioting, Daewongun was accused of fomenting the disturbance and its violence. Daewongun was arrested by Chinese troops. He spent 3 years in China and returned to Korea in 1885.
The Japanese government sent Ambassador Hanabusa back to Seoul. His security was ensured by four naval warships, three cargo ships and a battalion of armed soldiers.
