Except in the south-east of Europe, where Greece, with the aid of Russia, Britain, and France, wrested her political independence from the grasp of the Sultan (1827), the forty years that succeeded Waterloo were broken by no important war; but they were marked by oft-recurring unrest and sedition.

Thus, when the French Revolution of 1830 overthrew the reactionary dynasty of the elder Bourbons, the universal excitement caused by this event endowed the Belgians with strength sufficient to shake off the heavy yoke of the Dutch; while in Italy, Germany, and Poland the democrats and nationalists (now working generally in accord) made valiant but unsuccessful efforts to achieve their ideals.
The same was the case in 1848.

The excitement, which this time originated in Italy, spread to France, overthrew the throne of Louis Philippe (of the younger branch of the French Bourbons), and bade fair to roll half of the crowns of Europe into the gutter.

But these spasmodic efforts of the democrats speedily failed.

Inexperience, disunion, and jealousy paralysed their actions and yielded the victory to the old Governments.
