Their military forces were also demobilized, with the daimyo and their samurai followers pensioned into retirement. The move to abolish the feudal domains effectively ended the daimyo era in Japan. This was effectively carried out through the financial collapse of the feudal-domain governments, hampering their capability for resistance. In the wake of the changes, many daimyo remained in control of their lands, being appointed as prefectural
