2. Types of Mechanisms

2.1. Balance of Power

1.1 Historical Roots

The balance of power is one of the oldest and most enduring mechanisms for maintaining international order. Emerging prominently in 17th- and 18th-century Europe, particularly after the Treaty of Westphalia (1648), the balance of power refers to the distribution of power among states so that no single state can dominate the international system. According to classical realist thinkers like Hans Morgenthau (1948), maintaining a balance of power is crucial for preventing hegemony and ensuring stability.

During the Concert of Europe (1815–1914), the balance of power mechanism was institutionalized following the defeat of Napoleon. The major European powers—Britain, Austria, Russia, Prussia, and later France—agreed to cooperate diplomatically to prevent the rise of a single dominant state and to suppress revolutionary movements that could destabilize the continent. Through regular conferences and strategic alliances, these powers managed to maintain relative peace in Europe for almost a century.

1.2 Mechanisms and Practices

The balance of power operates through several mechanisms:

  • Alliances: States form coalitions to counter the power of a potential hegemon (e.g., alliances against Napoleonic France or Nazi Germany).

  • Arms build-ups: States increase their military capabilities to deter aggression.

  • Compensation and territorial adjustments: Redistributing territories to maintain equilibrium.

  • Intervention: Powers may intervene in weaker states to preserve the balance (e.g., interventions during the 19th century to maintain status quo in Europe).

1.3 Strengths and Limitations

The balance of power provides a pragmatic framework for managing conflict among states. It assumes that rational actors seek to prevent domination and that alliances can create deterrence. However, it has limitations. The system relies on accurate perceptions of power, consistent commitment to alliances, and rational decision-making. Miscalculations—such as during the lead-up to World War I—can result in catastrophic breakdowns. Moreover, the balance of power does not eliminate conflict; it simply manages it to prevent systemic collapse.
