What happened when balance of power was not maintained?

When the balance of power is not maintained, it often leads to increased tensions and conflicts between nations or groups, as one party may become dominant and threaten the interests of others. Historical examples include the lead-up to World War I, where alliances and militarism disrupted the balance, leading to widespread warfare. Additionally, power vacuums can emerge, resulting in instability and conflict, as seen in regions like the Middle East following the decline of established powers. Ultimately, the failure to maintain a balance of power can result in prolonged conflicts and shifts in global dynamics.
