The document summarizes the political developments in Europe following Napoleon's defeat in 1815. The Great Powers (Russia, Prussia, Austria, Britain, and France) established the Congress system to suppress revolutionary and liberal ideas and uphold the status quo. However, nationalist and revolutionary sentiments continued to emerge across Europe and Latin America, challenging the conservative order. By the 1820s, the Congress system began to break down as it was unable to contain new political realities, such as the independence movements in Latin America and revolutions in Spain, Naples, and Russia.
