The Revolutions of 1848 in the German states

The revolutions of 1848–49 in the German states, the opening phase of which was also called the March Revolution (German: Märzrevolution), were initially part of the Revolutions of 1848 that broke out in many European countries. They were a series of loosely coordinated protests and rebellions in the states of the German Confederation, including the Austrian Empire. The revolutions, which stressed pan-Germanism, demonstrated popular discontent with the traditional, largely autocratic political structure of the thirty-nine independent states of the Confederation that inherited the German territory of the former Holy Roman Empire. They demonstrated the popular desire for the Zollverein movement.

The middle-class elements were committed to liberal principles, while the working class sought radical improvements to their working and living conditions. As the middle class and working class components of the Revolution split, the conservative aristocracy defeated it. Liberals were forced into exile to escape political persecution, where they became known as Forty-Eighters. Many immigrated to the United States, settling from Wisconsin to Texas.

The groundwork of the 1848 uprising in Germany was laid long beforehand. The Hambacher Fest of 1832, for instance, reflected growing unrest in the face of heavy taxation and political censorship. The Hambacher Fest is noteworthy for the republicans adopting the black-red-gold colours (used on today's national flag of Germany) as a symbol of the republican movement and of unity among the German-speaking people.

Activism for liberal reform spread through many of the German states, each of which had distinct revolutions. They were also inspired by street demonstrations of workers and artisans in Paris, France, from February 22 through 24, 1848, which resulted in the abdication by King Louis Philippe of France and his going into exile in Britain. In France the revolution of 1848 became known as the February Revolution.
