What were the main causes and results of the revolutions of 1848?

In the late 1840s Europe entered a period of tense economic and political crisis. Bad harvests across the continent caused widespread distress. Uneven industrial development failed to provide jobs or raise incomes, and revolts and insurrections rocked Europe: a rebellion in the northern part of Austria in 1846, a civil war in Switzerland in 1847, and an uprising in Naples, Italy, in January 1848.

Full-scale revolution broke out in France in February 1848, and its shock waves ripped across the continent. Only the most developed countries — Great Britain, Belgium, and the Netherlands — and the least developed — the Ottoman and Russian Empires — escaped untouched. Elsewhere governments toppled, as monarchs and ministers bowed or fled. National independence, liberal democratic constitutions, and social reform: the lofty aspirations of a generation seemed at hand. Yet in the end, the revolutions failed.
