Although nominally a league of equals, in practice the empire was dominated by the largest and most powerful state, Prussia.
The period of Bismarck was considered a golden era under whom, Germany rose to become one among the greatest powers of the world. The imperial crown was hereditary in the House of Hohenzollern, the kings of Prussia. The last king in the Prussian era was William II. William became internationally known for his aggressive foreign policy positions and strategic blunders which pushed the German Empire into political isolation and later into World War I. Under William II, Germany no longer had long-ruling strong chancellors like Bismarck. William II wanted Germany to have its "place in the sun" like the British Empire and set Germany to begin colonial efforts in Africa and the Pacific. With much territory in Africa colonized, Germans got only a small share. This created a fight for power, which eventually triggered World War I.
Emperor William II abdicated the throne and then Government received an armistice on November 11, 1918 which marked the end of World War I. It also signed the Humiliating Versailles treaty. The imperialism was succeeded by the democratic, yet flawed, Weimar Republic. It was doomed from the beginning since even moderates disliked it and extremists on both the left and right loathed it. It eventually brought Nazis led by Adolph Hitler to power.
Nazism or National Socialism refers primarily to the ideology and practices of the Nazi Party under Adolph Hitler; and the policies adopted by the government of Nazi Germany from 1933 to 1945. It established a kind of imperialism on Germany and despised Jews and communists. It ruled Germany during the pre-war period and Hitler became "The Fhrer". He started World War II citing the humiliation of Germany in World War II. Germany was defeated by allied forces in the War.
Following Germany's defeat in World War II and the beginning of the Cold War, Germany was split, representing the focus of the two global blocs in the east and west. International plans for the unification of Germany were made during the early years following the establishment of the two states, but to no avail. During the summer of 1989, rapid changes took place in East Germany, which ultimately led to German reunification. Only in 1990 would Germany be reunited. Towards end of the Century, Germany became the centre of attraction in European Union. It is one of the most industrialized and developed nations of the world. (The Causes of World War One (2004))
The German Empire had a strong influence on German culture, including its education. Kingdom of Prussia was among the first countries in the world (if not the first at all) to introduce free and generally compulsory primary education, consisting of an eight-year course of primary education, Volksschule. Under the German Empire the school system became more centralized. More secondary schools were established, and the state had the right to set standards and to supervise the newly established schools. Four different types of secondary schools developed: A nine-year classical Gymnasium (focusing on Latin and Greek or Hebrew, plus one modern language), a nine-year Realgymnasium
