Samurai who brokered the Satsuma-Choshu Alliance.
Compare Sakamoto Ryoma with another historical figure:
Ryoma established a trading company in Nagasaki with the goal of modernizing Japan's economy and military. The company imported Western weapons and ships, and served as a base for anti-shogunate activities.
Ryoma mediated between the Satsuma and Choshu domains, which had been hostile to each other. Through his negotiations, the two domains agreed to cooperate against the Tokugawa shogunate, forming a key alliance that enabled the Meiji Restoration.
Ryoma drafted a political reform plan proposing a new government structure for Japan, including a bicameral legislature, a constitution, and the return of power to the imperial court. The plan influenced the Meiji government's early policies.
Ryoma was assassinated at the Omiya inn in Kyoto by agents of the shogunate. His death at age 31 cut short his political influence, but his ideas continued to shape the Meiji Restoration.
