The Revolutions of 1830 were a revolutionary wave in Europe which took place in 1830. It included two "romantic nationalist" revolutions, the Belgian Revolution in the United Kingdom of the Netherlands and the July Revolution in France along with rebellions in Congress Poland, Italian states, Portugal and Switzerland. It was followed eighteen years later, by another and much stronger wave of revolutions known as the Revolutions of 1848.
Liberty Leading the People by Eugène Delacroix commemorates the July Revolution.

A revolutionary wave or revolutionary decade is one series of revolutions occurring in various locations within a similar time-span. In many cases, past revolutions and revolutionary waves have inspired current ones, or an initial revolution has inspired other concurrent "affiliate revolutions" with similar aims.
The causes of revolutionary waves have become the subjects of study by historians and political philosophers, including Robert Roswell Palmer, Crane Brinton, Hannah Arendt, Eric Hoffer, and Jacques Godechot.
