As the foundation work of Italian conservative politics, Mosca pointed out in "The Ruling Class" that there are two diametrically opposed classes in any society-the ruling class and the ruled class. The ruling class is generally composed of warriors, priests, landed aristocrats, wealthy and knowledgeable groups. They manage national affairs, monopolize state power, and monopolize various honors. Because only these few people have the ability to organize, while the majority of the people are in an unorganized state. The dominance of the organized minority over the unorganized majority is therefore inevitable. After a given ruling class loses power, another takes its place. In fact, the entire history of human civilization is written by the struggle between the ruling classes and their competitors. Mosca's conclusion greatly influenced and contributed to the rise of "elite theory" in Western political science.
