16. Claudius II Gothicus

Claudius 11 Gothicus replaced the highly unpopular and inefficient emperor Gallienus and was declared emperor by his troops. Known for his military prowess, Claudius defeated many enemies, and is most known for defeating the Alemanni in battle. He also won against the Goths in battle.
