Hirohito
Hirohito was the emperor of Japan during the Second Sino-Japanese War  which became World War 2 (1931 to 1945). Though he was supposed to be an absolute monarch (an emperor who can make all the laws and rules), most of the power in the Japanese Government during this time was held by Japan's Prime Minister Hideki Tōjō and the military. Hirohito's role in WW2 is controversial.
