A shogunate refers to a form of military government in Japan, led by a shogun who holds the highest authority, while the emperor serves as a symbolic figurehead. This system emerged during the late Heian period and became prominent during the Kamakura period, marking a shift in power from the imperial court to military leaders. The shogunate played a crucial role in Japan's state-led industrialization by centralizing authority and implementing policies that fostered economic and technological development.
