.

In the 1860s, Satsuma tended to take a moderate position towards maintenance of the status quo, whereas Chōshū had become the center of an uprising aimed at overthrowing the government. Through the mediation of

Katsura Kogorō of Chōshū Domain. Although the two domains were traditionally fierce enemies, their leaders agreed that the time was right for a change, and agreed in principle to assist one another in the event that either would be attacked by a third party.[1] Also, Chōshū desperately needed modern weapons, but had very limited contacts with the western powers. Satsuma, on the other hand, had developed a substantial arms trade with Great Britain via Thomas Glover, a Scottish merchant affiliated with Jardine Matheson. At the suggestion of Sakamoto, Saigo helped broker an agreement to supply Chōshū with the weapons it needed to fight the Tokugawa shogunate.[2]

Despite this assistance, there was still considerable distrust between the two domains. On March 1, 1866, the Shogunate demanded the retirement and confinement of Chōshū

Imperial Court. If this failed and the Shogunate attacked, Satsuma would send 2000 troops to Kyoto; however, Satsuma would engage the Shogunate in combat only if Kuwana, Aizu or Tokugawa Yoshinobu's personal guard attempted to block Satsuma's access to the Emperor.[3]

The Alliance was crucial in enabling Chōshū to withstand a punitive expedition mounted by the Tokugawa shogunate in the summer of 1866, which led to a stunning defeat for the Tokugawa armies. During the subsequent Boshin War of 1868–1869, the imperial armies which finally overthrew the Shogunate were primarily samurai from the Satchō alliance. With the establishment of the Meiji Restoration, men from these two domains dominated the new Meiji government into the 20th century.[4]
