This is an analysis of how fin-de-siècle Vienna and its mayor, Karl Lueger, influenced the development of Adolf Hitler’s worldview. The works of many authors were consulted in conjunction with newspapers and memoirs of the period in order to gain a better understanding of what the environment of the Austrian capital was like in the fin-de-siècle period. Several of Vienna’s political, social, and artistic facets are analyzed in an attempt to prove that the general atmosphere of the city influenced Adolf Hitler greatly during his formative years. It is concluded that while Adolf Hitler’s Weltanschauung did not completely crystallize until after World War I, much of what contributed to his personal and political ideology resulted from his personal experiences in Vienna.
