He would hold it in his grasp until his death in 1945, establishing a dictatorship that lasted more than 20 years. Long considered a buffoon and a second-rate dictator, Il Duce invented fascism that was imitated by Hitler, who viewed the Italian as his political master. He wanted to transform his country into a warrior nation and promised Italians a return to the grandeur of the Roman Empire. He governed by violence and trickery and was one of the first populist leaders of modern times, leading his country into the catastrophe of the World War II.
