Knowledge 1: Literature of East Germany
East German literature is the literature produced in East Germany from the time of the Soviet occupation in 1945 until the end of the communist government in 1990. The literature of this period was heavily influenced by the concepts of socialist realism and controlled by the communist government. As a result, the literature of the German Democratic Republic (East Germany) was for decades dismissed as nothing more than "Boy meet Tractor literature", but its study is now considered a legitimate field. Because of its language, the literature is more accessible to western scholars and is considered to be one of the most reliable, if not the most reliable, sources about East Germany.
