The Congress of Vienna established a conservative balance of power in Europe that aimed to maintain the status quo and suppress revolutionary and liberal ideals. However, this conservative order was challenged by the rise of nationalism and liberalism in the early 19th century. Revolutions in places like France and Greece in the 1820s-1830s showed the limitations of the Congress system, as it failed to account for popular aspirations to self-government and liberal reforms. While the conservative order was restored each time, the revolutions indicated the conservative settlement was beginning to crack under pressure from new political ideologies.
