Definition
In plain language
The idea is that countries stay safe when power is spread out so that no one country can dominate the rest. If one grows too strong, others join against it.
Academic definition
Balance of power theory holds that States, seeking survival in an anarchic system, will ally against or build up power to offset a potentially dominant State. Classical diplomacy used it in the Treaty of Utrecht (1713), which referred to a balance of power in Europe, and in the nineteenth-century Concert of Europe. Waltz's Theory of International Politics (1979) gave it a structural form, while critics such as Wendt and liberal theorists argue that identity and institutions matter as much as the distribution of capabilities.

Context
Legal effect: Not a Legal Term
Scope
Covers the doctrine and its use in foreign policy; the 'balance of power' as a descriptive state of affairs and hegemonic stability theory, which holds that dominance can bring stability, are separate.
Legal context
not_applicable
Diplomatic context
Governments cite it to justify alliances, arms build-ups and interventions to prevent regional dominance, and diplomats talk of 'restoring the balance' in negotiations.
Institutional context
Used by foreign ministries, defence planners and think tanks; no institution owns the doctrine.
Historical context
European diplomacy applied it from the Renaissance and the seventeenth century, especially after Utrecht and the Congress of Vienna in 1815, and Cold War bipolarity was often described in its terms.
Why it matters
The doctrine shapes alliance choices, arms control and responses to rising powers, and misreading it can lead to arms races or overreaction.
Usage
Register: Academic
Usage note
'Balance of power' is not a rule of international law and should not be written as if it were an obligation.
Example
The coalition formed in response to the rising power's expansion, a classic case of balance of power politics.
Example scenario
A regional power begins building forces that worry its neighbours. State A and State B form an alliance and increase defence spending to offset it, and the first power responds by seeking its own partners.
Common misuse
Treating it as a legal principle or assuming it always produces peace; history shows balances can fail and spark wars.
