Introduction The paper discusses the chief ideas associated with the ideology of liberalism, nationalism, and early utopian socialism. The reasons as to why these ideologies were considered revolutionary by many people are also examined. The paper has also highlighted the differences between these ideologies. Liberalism Liberalism is a political belief and it fosters the thought that the liberty of individuals is the most important goal to be achieved. There are many sub ideologies in this and each is related to a specific sphere of life. Some of them are Political liberalism, Cultural liberalism, Economic liberalism, Social liberalism, Paleoliberalism, Ordoliberalism, Liberal feminism, Classical liberalism, and many more. The term originated in ancient Rome when the patricians and plebeians fought with each other over liberty and the right of an individual for free enterprise, freedom from persecution, and the right to practice their own religion. All along with the history of western civilizations, liberalism has come up in different ways and in Britain, it was the fight between the Catholics and Protestants, during the American Revolution and many other issues. The ideology was considered revolutionary since it pitted the weak against the strong, the oppressor, and the oppressed, and depending on whose side one was, the fight was either a revolution or an uprising or rebellion. In modern times, this ideology has assumed different meanings and terms like liberalization of the economy and globalization have come up. In effect, the ideology believes that man, economy, culture, art, and all other disciplines should be open to the market forces and while the government may have some regulatory powers, undue interference should be avoided (Spielvogel, 2005). Nationalism Nationalism is an ideology that believes in creating and adhering to a nation and a national identity. The belief is that people should forget their regional differences and unite to take a part in building national pride. Individuals are not given prominence and it is the nation that comes first. The term gained importance as an s social movement during the French revolution and later on during the world wars. It should be noted that all along with history, people had always claimed allegiance to a king or a lord who ruled over a territory. However, nationalism transcended these small territories and engulfed them, giving all the people who may speak different languages, a single national identity. The reason why Nationalism is considered revolutionary and even dangerous is because of the extremism it fosters among the dominant group in a nation. Dominant groups in Germany included the Nazi, Italy had the Fascists, Soviet Russia had the communists, and Vietnam had the Khmer Rouge and many other such malevolent groups. Such groups attempted to terrorize minority groups in a nation and under the guise of building the nation or national pride, unleashed mass killings of anyone who opposed their dogma. While the ideology has noble intents, the application is very negative and hence Nationalism and Nationalists are treated with distaste (Spielvogel, 2005). Early Utopian Socialism Early
