Why did the emperor give the leader of the Minamoto family the title of shogun?
I think they did that because the emperor didn't want to give up being emperor
The Shogunate is established in Japan when Minamoto Yoritomo was one of the greatest statesmen Japan had ever produced.He was the founder of Japan's military government known as the SHOGUNATE. The chief military officer of shogunate is called "SHOGUN". A shogun controls the law,the courts and appointments to office. MINAMOTO YORITOMO,the elder brother of MINAMOTO YOSHITSUNE,became the first Shogun of Japan.
One would think that an Emperor has more power than a Shogun However, this is incorrect, a Japanese Shogun is a person of military rank and historical title and in most cases, he is the hereditary military dictator of Japan and has more power than an Emperor. He is also the leader of the Samurai. An Emperor is merely a figure head.
