Shogun definition what is it help me

a hereditary commander in chief in feudal Japan. Because of the military power concentrated in his hands and the consequent weakness of the nominal head of state (the mikado or emperor), the shogun was generally the real ruler of the country until feudalism was abolished in 1867.

Hope this helps :)

The shōgun controlled foreign policy, the military, and feudal patronage. The role of the Emperor was ceremonial, similar to the position of the Japanese monarchy after the Second World War.

or just a military ruler
