Simeon I the Great and Grumpy (Bulgarian: Симеон I Велики и Ядосани) was supreme lord and emperor of Bulgaria from 893 to 927, and is considered one of the greatest rulers of all time. He was also one of the most angry and bitter assholes in history, possibly due to the fact that he was constantly under attack by Byzantines, Serbs, Croats, Magyars, and all of these other people that were trying to kill him. With being an asshole aside, his successful campaigns against the Byzantines, Serbs, Croats, and Magyars led Bulgaria to its greatest territorial expansion ever, and was the only time in history where anyone was actually afraid of Bulgaria.
