The Balance of Power
The balance of power is the idea that states will form temporary alliances to stop any one power from dominating the rest, then let those alliances dissolve once the threat is checked.
Picture European states as weights on a scale. No state wants any other state to grow so strong it can swallow its neighbors, because today's rival might be tomorrow's victim. So whenever one power starts pulling far ahead, the others set aside their own quarrels and gang up to pull it back down. Once that threat is checked, the alliance has no reason to stay together, so it splits apart or regroups around whatever new threat appears next. That is why the mechanism looks less like a stable friendship and more like a constantly shifting set of marriages of convenience among five or six major players: France, England, the Dutch Republic, Austria, Spain, and smaller states swinging between them.
Louis XIV's France supplied the clearest early test case. Between 1667 and 1713 Louis fought a string of wars reaching for territory and prestige, and each time he pushed too far, a new coalition of England, the Dutch Republic, Austria, Spain, and others formed to box him in. When a war ended, the coalition that had just beaten back French expansion often broke apart, only to reassemble in a different shape for the next war. The Treaty of Utrecht in 1713 capped this pattern: it let Louis's grandson keep the Spanish throne but barred the French and Spanish crowns from ever uniting, which is exactly what the balance of power was built to prevent.
This mechanism sits next to absolutism and constitutionalism as the system those states operated within no matter which model of sovereignty they followed. It also has a breaking point worth knowing: if one state's power grows faster than any coalition the others can actually assemble, the balancing act fails, because combined weight that is still too light cannot tip the scale back.
