What Is Power in Global Politics?
In global politics, power refers to the ability of an actor to influence decisions, shape outcomes, or affect the behaviour of others on the international stage. Within the IB Global Politics course, power is treated as a core and contested concept, meaning it is central to political analysis but understood differently depending on perspective, context, and theory.
Traditionally, power has been associated with states and their material capabilities. From this viewpoint, power is often measured through military strength, economic wealth, population size, and control over territory. States with greater resources are assumed to have more influence over international events such as wars, trade negotiations, and diplomatic agreements. This understanding aligns closely with realist theories of global politics, which prioritize survival, security, and competition.
However, the IB Global Politics framework expands this definition significantly. Power is also relational, meaning it exists within relationships between actors rather than being something an actor simply possesses. A state may be powerful in one context but weak in another, depending on who it is interacting with and what issue is at stake. For example, a small state may exert influence through alliances, strategic geography, or moral authority despite limited material resources.
Power can also be structural, embedded within global systems and institutions. International organizations, legal frameworks, and economic systems can shape outcomes by determining who sets the rules and whose interests are prioritized. Structural power often operates invisibly, benefiting certain actors while constraining others without direct coercion. This form of power is particularly relevant when analysing global inequality and development.
Another key dimension is ideational power, which involves shaping ideas, values, and norms. Actors that influence how issues are understood—such as defining what counts as “security,” “development,” or “human rights”—can shape global agendas without using force or money. Media narratives, education systems, and cultural influence all play important roles in ideational power.
Finally, power in global politics is dynamic and changing. Globalization, technological advances, and the rise of non-state actors have altered how power is distributed and exercised. Power today is more diffuse, with influence spread across states, corporations, international institutions, and civil society.
