“When France sneezes, the rest of Europe catches a cold”. These words were spoken by Austrian Chancellor Duke Metternich. His words pointed to the influence that France had on entire Europe in the 19th century.

Liberals in France overthrew the Bourbon dynasty through their constant efforts in 1830, which instilled a sense of nationalism in other European nations.
