National Socialism, often associated with the Nazi Party, was a political ideology that emerged in Germany during the early 20th century. It combined elements of nationalism, racism, and totalitarianism, promoting the idea of a superior Aryan race and advocating for the expansion of German territory. The movement gained significant power under the leadership of Adolf Hitler, leading to the establishment of a dictatorship. The regime implemented policies that resulted in widespread discrimination, particularly against Jews, Romani people, and other minority groups. National Socialism also emphasized militarism and sought to create a centralized economy, ultimately leading to World War II and the Holocaust, which caused immense suffering and loss of life.
