Anderson argued that the prerequisites for the rejection of these beliefs began in Western Europe through the numerous factors that led to the Age of Enlightenment, such as the power of economics, the scientific revolution, and the advent of improvements in communication brought about by the invention of the printing press under a system of capitalism (or as Anderson calls it, print capitalism). Anderson's view of nationalism places the roots of the notion of "nation" at the end of the 18th century when a replacement system began, not in Europe, but in the Western Hemisphere, when countries such as Brazil, the United States, and the newly freed Spanish colonies became the first to develop a national consciousness.
