Emperor Hirohito reigned in Japan during World War II and although the accusations made against his leadership are not as significant as some others on this list, the debate still rages as to whether or not he was responsible for the war crimes committed by his military and how much control he really had.
Like Emperor Hirohit, Koki’s ability and power to affect the atrocities committed by the military was questionable. Unlike Hirota, however, he was executed for war crimes that included being privy to information that could have prevented numerous atrocities.
Leonid Ilyich Brezhnev
Being a communist leader for the Soviet Union, it should come as no surprise that Leonid Brezhnev fit right into the senselessly violent shoes of his predecessors, Stalin and Lenin. His leadership was marred with the blood of genocide against the Moldovans, Volga Germans, Cossacks, Poles, and even Armenians.
As the successor of Sun Yat-sen, Chiang Kai-shek of China was a very formidable leader whose ideals, goals, and dreams were for the sake of giving China a whole new government, away from the common ground of Communism which had lasted for so many years. He was known as the “White Terror”, purging the opposition for better leadership and country stability. All in all roughly 1 million died as a result of his initiatives.
Kaiser Wilhelm II
Kaiser Wilhelm II was the last emperor of Germany up until 1918. Know for his inability to control the military and inept command, he probably wasn’t nearly as deadly as he was incapable. Nevertheless, his time as emperor caused the deaths of millions.
