The Revolutions of 1848 saw widespread uprisings across Europe motivated by nationalism, liberalism, and romanticism. In France, restrictions on freedoms by King Louis Phillip led to an uprising in Paris and the establishment of the Second Republic. Louis Napoleon, Napoleon Bonaparte's nephew, was elected president but later dissolved the assembly and declared himself Emperor Napoleon III. The revolutions in France also inspired liberals in Prussia and the formation of a parliament in Frankfurt to draft a constitution for a unified Germany, though these efforts ultimately failed. Russia helped crush revolutionary movements and supported the resistance to reform in Prussia and Austria. In England, a planned march on London by Chartists was prevented by military forces, weakening the Chartist movement
