The German nationalist movement emerged in the 19th century, driven by a desire for national unity and independence among the various German-speaking states. It sought to promote a shared cultural identity, language, and history, often emphasizing the importance of a unified Germany. Key events, such as the Frankfurt Assembly of 1848, aimed to establish a unified German nation-state. The movement gained momentum with the leadership of figures like Otto von Bismarck, who played a crucial role in the unification of Germany in 1871, ultimately leading to the establishment of the German Empire.
