State responses similar to those discussed in the source are an example of what historical development of the 19th and 20th

In the late 19th century, between roughly 1875 and 1900, a handful of European nations conquered most of Africa. Since this came after more than three centuries of relatively cooperative trading activity between Europeans and Africans, it represents a significant departure in world history. This "Age of Imperialism" also had long-range consequences including the spread of European languages around the globe, the creation of borders that sparked many subsequent conflicts, and the construction of institutions that made globalization possible. As a consequence, this course begins with an examination of European and African societies in the 19th century in order to determine why Europeans chose to invade Africa in the late 19th century.

Confident in the superiority of their culture and institutions, Europeans looked for the same in the rest of the world, and related to other societies as if they existed on a continuum from "primitive" to "developed." In assigning these positions, Europeans looked especially at the level of material culture and the size of political institutions. By these criteria, northern Europeans occupied the top end of the continuum while southern Europeans, Arabs, Chinese, Native Americans and other groups occupied lower positions. Black non-Muslim Africans were near the bottom, just ahead of Australian aborigines.
