Why the some people said that …

The Revolutions of 1848, known in some countries as the Spring of Nations, People's Spring, Springtime of the Peoples, or the Year of Revolution, were a series of political upheavals throughout Europe in 1848. It remains the most widespread revolutionary wave in European history.
The revolutions were essentially bourgeois revolutions and democratic and liberal in nature, with the aim of removing the old monarchical structures and creating independent nation-states. The revolutions spread across Europe after an initial revolution began in France in February. Over 50 countries were affected, but with no significant coordination or cooperation among their respective revolutionaries. Some of the major contributing factors were widespread dissatisfaction with political leadership, demands for more participation in government and democracy, demands for freedom of the press, other demands made by the working class, the upsurge of nationalism, and the regrouping of established government forces.
