Regality theory is a theory expressing that people show a preference for strong leadership in times of war or collective danger, but a preference for an egalitarian political system in times of peace and safety. These psychological orientations in individuals are emulated in the political structure and culture of the entire society. A society in danger and conflict will advance in the direction called regal structure. This culture is built on the foundations of strong nationalism, discipline, strict religiosity, patriarchy, strict sexual morals, and perfectionist art. On the contrary, a society in peaceful and safe environment will develop in the opposite direction called kungic, which is a type of culture that includes the principles of egalitarianism and tolerance. High individualism, high sexual freedom, low birth rate, and long childhood and education are major characteristics of the kungic society. Regality theory and kungic theory are important concepts applied to the study of warlike and peaceful societies. This book is compiled in such a manner, that it will provide in-depth knowledge about the regality theory. The readers would gain knowledge that would broaden their perspective about this theory as well as its implications.
