Prince Klemens von Metternich's policy of reactionary conservatism was a political approach aimed at preserving the traditional structures of power and society in Europe following the upheavals caused by the French Revolution and Napoleonic Wars. This policy sought to maintain monarchical authority, suppress revolutionary movements, and promote a social order based on hierarchy and privilege. Metternich's actions laid the groundwork for the Concert of Europe, which aimed to create a balance of power that would prevent further revolutions and maintain stability across the continent.
