Power transition theory

Power transition theory is a theory about the nature of war, in relation to the power in international relations. The theory was first published in 1958 by its creator, A.F.K. Organski, in his textbook, World Politics (1958).

According to Organski:

An even distribution of political, economic, and military capabilities between contending groups of states is likely to increase the probability of war; peace is preserved best when there is an imbalance of national capabilities between disadvantaged and advantaged nations; the aggressor will come from a small group of dissatisfied strong countries; and it is the weaker, rather than the stronger power that is most likely to be the aggressor.
