In the 19th century Napoleon took power and established the First French Empire , whose subsequent Napoleonic Wars shaped the course of continental Europe . Following the collapse of the Empire , France endured a tumultuous succession of governments culminating with the establishment of the French Third Republic in 1870 . France was a major participant in the First World War , from which it emerged victorious , and was one of the Allied Powers in the Second World War , but came under occupation by the Axis Powers in 1940 .
