Starting with the Convention of Kanagawa in 1854, within a few years foreign powers forced the shogun dynasty to abandon its isolationist policy sakoku.
The rebellion reflected the widespread discontent felt among both pro-imperial/anti-shogunate and anti-foreigner groups, who rebelled under the sonnō jōi ("revere the emperor, expel the barbarians") slogan.
Thus, in March 1863, the shishi rebels sought to take control of the Emperor to restore the Imperial household to its position of political supremacy.
It is unknown if the rebels set fire to Kyoto as soon as they began to lose, or if their doing so was part of their original strategy, and done as a diversionary tactic.
Various courtiers, including Nakayama Tadayasu, the Emperor's Special Consultant for National Affairs, were banished from Court as a result of their involvement in this incident.
