French art has long since dominated within Europe since around the middle of the 19th century when it came upon a long spate of imaginative artists who helped push on ideas from previously traditional styles that were starting to appear stale to those who were more contemporary-minded. The Renaissance had been heavily led by artists from Italy and then France took the lead in a similar way around the 19th century thanks to painters like Henri Rousseau plus the impressionists.
