During the early 19th century, inspired by romanticism, classicism, former movements of Greek nationalism and failed Greek revolts against the Ottoman Empire (such as the Orlofika revolt in southern Greece in 1770, and the Epirus-Macedonian revolt of Northern Greece in 1575), Greek nationalism led to the Greek war of independence. The Greek drive for independence from the Ottoman Empire in the 1820s and 1830s inspired supporters across Christian Europe, especially in Britain, which was the result of western idealization of Classical Greece and romanticism. France, Russia and Britain critically intervened to ensure the success of this nationalist endeavour.
