The revolution of 1848 was often called "Spring of the masses" and symbolized the era of political and social unrest spread throughout the European continent. During this period we considered the overthrow of the monarchy, the formation of a new state, and the "extreme ideology" of nationalism and liberalism as a belief in the middle class. The population of European countries is increasing at an unprecedented rate. The public began to feel uneasy about the monarchy of the governance system of the European government in the 19th century and hoped to achieve individual freedom and equality through the change.
Nationalism also determines the political life of Europe in the 19th century. Where the country is part of the empire, the struggle for national liberation is also a struggle against the old dictatorial regime, and nationalism is tied to the free anti mona movement. As in Spain, the nation state is the integration of the old monarchy, nationalism itself is conservatism and monarchy. Most nationalist movements began to oppose the existing order, but by the 20th century some governments regarded themselves primarily as nationalism.
Political nationalism is a complex and diverse phenomenon. Its main forms are liberalism nationalism, conservative nationalism, expansionism nationalism, anti-colonialism nationalism. Free nationalism gives the state a moral status similar to that of an individual. That means the state has rights, in particular self-determination power. Because liberalist nationalism thinks that all countries are equal, we insist that the ideals of the nation state are universally applicable. Conservative nationalism not only pay attention to the principles of self-determined nationalism, but also pay attention to social cohesion and public order promised by national patriotism. From this point of view patriotic loyalty and public awareness are rooted in the common past concepts and have transformed nationalism into advocacy of traditional values and historical systems.
In the political tradition of liberalism, people criticized "nationalism" as being generally a dangerous power and being the cause of conflict and war between states. Liberals generally do not question the existence of a nation state. Liberal criticism also emphasizes individual freedom, not collective national identity by definition (see collectivism). Criticism of pacifism's nationalism also focuses on nationalistic conflicts that gained hints on nationalist movement violence, related militarism, and chauvinism and chowningism. Especially in Germany, from the historical connection with the past war, the symbol of the country and patriotism lost credibility.
