Model Essay (About 350 Words)

Between 1919 and 1933, many Germans lost faith in democracy and looked for more extreme solutions. From the perspective of an ordinary German, the Treaty of Versailles, the weaknesses of the Weimar Constitution, repeated economic crises, and Nazi promises all pushed people either toward or away from Adolf Hitler.
