The Prussian nobility, known as the Junker class, played a significant role in the history of Prussia and later the German Empire. They were landowners who held significant political and military power, often serving as officers in the Prussian Army. Their influence was rooted in a feudal system that emphasized loyalty to the state and the monarchy. During the 19th century, the Prussian nobility faced challenges from rising bourgeoisie and democratic movements. Despite these pressures, they maintained a strong cultural identity and continued to influence German politics and society. The decline of their power began after World War I, leading to the eventual abolition of their privileges in the Weimar Republic.
