What caused the German Revolution of 1848?

The social demands of artisans and some factory workers were put down quickly. Democracy persisted in France. Peasant demands were met, and serfdom was fully abolished throughout Western Europe. The failure of the revolution taught many liberals and working class leaders that revolution was too risky. Many governments also installed better riot control police. And at the end with the industrialization, social structure came to rest less on privilege and birth and more on money.
