The Revolutions of 1848, also known as the "Spring of Nations" were a series of revolts caused by political movements that spread through Europe during this year. These upheavals were initiated by the French Revolution, and although not coordinated, spread to more than 50 countries throughout Europe. Common demands included freedom of the press, demands for more social participation in government, and labor-related demands by the working class.
