The Kamakura government, also known as the Kamakura shogunate, was a feudal military government in Japan that lasted from 1185 to 1333. It was established by Minamoto no Yoritomo after his victory in the Genpei War, marking the beginning of the samurai's political power in Japan. The government was characterized by a dual system of rule, where the emperor retained nominal authority while real power was held by the shogun. The Kamakura government implemented a system of regional governance through shugo (military governors) and jito (land stewards), which helped maintain order and manage land. This period saw the rise of the samurai class and significant cultural developments, including the spread of Zen Buddhism. The government ultimately fell due to internal strife and external pressures, leading to the rise of the Ashikaga shogunate.
