In its simplest form, the Nazi Party command structure was divided into four basic levels: the general membership known as the Parteimitglieder, the political leadership corps known as the Politische Leiters, the upper command levels of the Party encompassed by the Gauleiters and Reichsleiters, and finally the position of Führer held solely by Adolf Hitler as supreme leader of the Party (a position of Deputy Führer also existed until 1941).
