Barricade
Barricade (the name is Spanish, probably from the barrels, Spanish barrica, originally used in their construction), an improvised fortification of paving stones, timber, or other material, best known in connection with the history of Paris. In 1588 troops marched in by Henry III. to terrorise the populace were fired at from behind barricades and suffered heavy loss. In the "three days'" revolution of 1830 some thousands of barricades were erected in Paris, and also during the revolution of 1848, and especially in June, 1849. The "Haussmannisation" of Paris, under Napoleon III., with its wide streets and asphalt pavements, was intended to prevent them in future, but many were constructed under the Commune of 1871. In 1821, in London, the funeral cortege of Queen Caroline was turned from its course by a large barricade at the junction of Marylebone and Hampstead Roads. The intention in this case was to prevent the evasion (desired by the Ministry of the day) of a demonstration of the popular feeling against George IV. In the revolutions of 1818 barricades were erected in various German towns.
