This paper examines nationalism as a sociological and political ideology, tracing its development over approximately two centuries alongside the rise of modern warfare. It explores how early 20th-century nationalism manifested in ethnic exclusivity — from Nazi Germany and Jim Crow laws to Zionism and Liberian colonization — before shifting toward cultural nationalism by the century's end. The paper also considers how globalization and cosmopolitanism challenged nationalist ideals without eliminating them, and how post-9/11 America and Taliban-controlled Afghanistan illustrate nationalism's continued divisiveness. The paper concludes that modern nationalism, whether isolationist or expansionist, poses a fundamental threat to collective security by dehumanizing those outside the national group.
The paper demonstrates effective use of historical comparison across multiple contexts — national, cultural, and geographic — to build a cumulative argument. Rather than relying on a single case study, the author draws parallels across radically different regimes and societies to show that nationalism is not a localized aberration but a recurring ideological pattern with consistent consequences for collective security.
The paper follows a chronological-thematic structure: it opens with a conceptual definition, moves through early 20th-century ethnic nationalism, transitions to late-century globalism and its limits, examines contemporary examples, and closes with a normative conclusion. Each paragraph introduces a new historical period or context while maintaining the central thesis about nationalism's threat to collective security and human dignity.
Nationalism is an ideology that focuses on a single nation. It stresses the welfare of the people in that nation over the welfare of the rest of the world's people and emphasizes national over local loyalty. Nationalism is a relatively new sociological phenomenon, having developed around two hundred years ago — roughly the same time as the modern concept of the nation itself. Its significance lies in the fact that its rise has occurred alongside the rise of modern warfare, and nationalism can be linked to alarming ideological trends.
Nationalists can range from extreme isolationists who fail to intervene in world problems — such as the United States after World War I — to nations bent on something closer to world domination, such as the Third Reich. Either variant leaves little room for individual difference. As a result, nationalism can keep countries from cooperating, whether out of indifference or fear, creating a barrier to effective collective security.
At the beginning of the 20th century, nationalism was characterized by a desire to develop a state or nation for each ethnic group. Nazi Germany, with its program to separate those it deemed "other" — including Roma, homosexuals, Catholics, and Jews — from the Aryan population, is the most widely recognized example of that form of nationalism. However, it is important to understand that other countries shared this type of exclusive nationalism as well.
In the southern United States, Jim Crow laws were aimed at prohibiting African Americans from mixing with the white population. While the northern United States was not so rigidly divided along color lines, it was not uncommon for the most recent immigrant groups to experience significant discrimination in major cities. Some minority groups, meanwhile, were advocating for the development of their own nations. Freed slaves, for instance, had success establishing Liberia as a colony and then an independent nation in Africa during the 19th century. Similarly, toward the end of the 19th century, some Jews began to push for the establishment of a Jewish state in Palestine — a movement that would become known as Zionism.
By the end of the 20th century, many world leaders began to reject the ideals of nationalism. Rather than stressing responsibility to one's own country, they began to emphasize responsibility to the world at large. The world economy was subject to globalization, and growing concerns about the effects of environmental pollution on all of humanity ushered in a growing sense of cosmopolitanism. However, that does not mean nationalism died out. On the contrary, many Western nations continued to engage in a form of cultural nationalism, linking financial and other forms of foreign aid to certain cultural conditions. Furthermore, though many countries discussed a global agenda, the majority continued to promote national interests at the expense of others, particularly third-world nations.
Nationalism can be a relatively benign phenomenon, much like an enhanced sense of patriotism. However, it is no longer a productive ideology in the modern era. In today's global economy, the reality is that all of the world's citizens will eventually pay for irresponsible behavior that may only impact certain groups today. Whether seeking to isolate a group from other cultures and ethnicities, or seeking to impose values on other countries, modern nationalism is dangerous to collective security because it inherently involves some degree of dehumanization of those outside one's own nation.
