What are the reasons and tasks of the revolution in 1848-1849 in France, Germany, Austria?

The revolutions in Europe in 1848-1849 carried the goal of getting away from the survivals of serfdom. They cannot be considered complete, because in France, after the revolution, the monarchy was restored, and in Germany and Italy the revolutionary movements were suppressed by the state. But the rebels managed to bring about changes in the social sphere and in the economy. Finally, feudal vestiges are a thing of the past. New forms of government were formed in the states. The power of many monarchs was limited to the constitution and parliament.
