The European Revolution of 1848 brought a series of political upheavals with their opposition to the traditional authority. There was a very strong dissatisfaction with political leadership and people started demanding more participation in the affairs of the states. Political awareness, ideas like liberty, equality and fraternity were popularised by the printing press.
The revolutions which were most important occurred in America, France, Germany, Italy and Russia.
Britain had already faced a major change with the Glorious Revolution. The United States of America was born after the American War of Independence and Russia experienced a workers’ movement which led to the establishment of a socialist government.
The American War of Independence and the French Revolution popularized the feeling of nationalism all over the world. The idea of nationalism from America, France and Britain influenced the Italians. The result was a revolution for a unified kingdom of Italy in 1861.
