In the introduction we briefly address the main topic of the paper. The second chapter continues to explain the economic situation in Germany and the world before the rise of the Nazi party. For the economic background we examine first the hyperinflation followed by the Great depression also known as the Wall Street Crash. The third chapter examines the NSDAP party and the role of Adolf Hitler. We present a chronology of the Nazi rise to the power explained in 25 points with which they wanted to control the situation in the country. The fourth chapter addresses German war-time economy. We analyse a change in GDP from the Great Depression until the end of the war and examine the role of industry in the economy. Before the conclusion we describe the state of German economy after the war and the consequences after the fall of the Third Reich.
