The primary outcome of the Treaty of Utrecht in 1713 was the establishment of a new balance of power in Europe following the War of the Spanish Succession. The treaty ended the conflict, recognizing Philip V as King of Spain but requiring him to renounce any claim to the French throne, thus preventing a unification of the two crowns. Additionally, it marked territorial adjustments, granting lands to various European powers and establishing the principle of collective security, which influenced future international relations.
