Why did Great Britain withdraw from the Concert of Europe?

Great Britain’s withdrawal from the Concert of Europe was primarily driven by a fundamental disagreement with the interventionist policies favored by the other great powers, particularly regarding the suppression of liberal uprisings in other nations.12

While the Concert system was initially established to maintain the post-Napoleonic status quo, tensions grew as the Holy Alliance (Austria, Russia, and Prussia) sought to intervene in the internal affairs of states facing rebellion. George Canning, who became British foreign secretary in 1822, held a strong antipathy toward this congress system.123

The breakdown was finalized following the Congress of Verona in 1822. During this meeting, the allies authorized a French intervention in Spain to overthrow its constitutional regime. Britain opposed this interference and used its naval power to prevent the allies from intervening in the revolts occurring in Spanish America. By creating significant discord among the allies, Britain effectively extricated itself from these European commitments, leading to the collapse of the congress system as an instrument of collective intervention.23
