The Bakumatsu era and the end of the shogunate and the warrior class
The beginning of the Bakumatsu era at the end of the Edo period is the subject of various theories, and can be dated to the 1820s and 1830s, when the shogunate's rule became unstable, or to the Tenpō Reforms of 1841–1843, or to Matthew C. Perry's arrival in Japan in 1853 and his call for the opening of the country. On the other hand, the end point is clear, when the 15th Shogun, Tokugawa Yoshinobu, returned the authority to govern Japan to Emperor Meiji.
