Hegemonic
stability theory (HST) is a theory of international relations. Based on study
from the fields of political science, economics, and history, HST specifies
that the international system is more likely to remain steady when a single
nation-state is the leading world power, or hegemon.
Thus, the fall of an
accessible hegemon or the state of no hegemon lessens the constancy of
international system. When a hegemon implements leadership, either through
diplomacy, coercion, or persuasion, it is in fact deploying its
"preponderance of power." This is called hegemony, which refers to a
state's skill to "single-handedly dominate the rules and arrangements
...[of] international political and financial associations.
