"Hitler neither developed his ideas in a vacuum nor rose to power alone. A rather motley crew of people formed his inner circle. Its membership changed many times, as people fell in and out of favor. Three individuals who stuck with Hitler throughout his political career and gained international profiles were Hermann Göring, Joseph Goebbels, and Heinrich Himmler. All of them would play key roles in the Nazi regime, each amassing enormous power even as they fought among themselves for Hitler's favor."
