the Kyoto Shoshidai normally went to fudai. Occasionally, a family could be raised to or from fudai status. For instance, the Matsudaira clan to which Matsudaira Sadanobu belonged went from being a fudai house to being a shinpan (recognized relative) of the Tokugawa family. Also, a hatamoto who had an increase in income which raised his income level over 10,000 koku became a fudai daimyō. Bakumatsu and Meiji Restoration Many fudai daimyōs were involved in the vigorous political activity of the Bakumatsu, the gradual decline of the Tokugawa Shogunate from 1853, and the renewed military activities which occurred in that period. Two such men of fudai daimyō background were Ogasawara Nagamichi and Itakura Katsukiyo, who were two of the last rōjū, and actively worked for reform and strengthening of the ailing shogunate. Others, such as Matsudaira Munehide, were involved in diplomacy and foreign affairs. In the Boshin War of 1868 to 1869, when supporters of the Imperial Court rose up in the Meiji Restoration against the Tokugawa Shogunate, some fudai houses such as the Toda of Ogaki and the Tōdō of Tsu sided with the shogunate during the first battle at Toba–Fushimi. However, after the shogunate's loss there, many fudai houses did not side with the shogunate or with remnants of the Shōgun's former army under Enomoto Takeaki which moved northward to Hokkaido and eventually set up the Ezo Republic. Some remained neutral, while others (like the lords of Ōgaki and Tsu) switched allegiances and openly supported the new Imperial Japanese Army. Ogasawara Nagamichi and Itakura Katsukiyo led small groups of their retainers during the fight against the Imperial forces. However, their domains had already been occupied by the Imperial army, and were forced to participate in the war on the Imperial army's behalf. Only one fudai daimyō, Hayashi Tadataka of Jōzai Domain, willingly left his domain early in 1868, and led most of his retainer force on behalf of the armies of the former Shōgun, in the fight against the Imperial army. Also, a handful of fudai in the north of Honshu formed part of the Northern Alliance, fighting for the Alliance but not for the now-retired Shōgun. Most of the fudai in the country entered the Meiji era peacefully, and ruled their domains until abolition of the domains in 1871. After this, the former families of fudai daimyōs transitioned into the kazoku in the new Japanese nobility system.
