A shogun was a military leader in Japan who held significant power, especially during the feudal period. The title originated in the 8th century and was officially established in the 12th century. Shoguns were responsible for governing the country, leading armies, and maintaining order, often ruling in place of the emperor, who held a more symbolic role. The most notable shogunate was the Tokugawa shogunate, which lasted from 1603 to 1868. This period was marked by relative peace and stability, known as the Edo period. The shogunate implemented strict social hierarchies and isolationist policies, limiting foreign influence and trade.
