Two devastating world wars and their aftermath made the Belle Époque appear to be a time of "joie de vivre" (joy of living) in contrast to 20th century hardships. It was also a period of stability that France enjoyed after the tumult of the early years of the Third Republic, featuring defeat in the Franco-Prussian War, the uprising of the Paris Commune, and the fall of General Georges Ernest Boulanger. The defeat of Boulanger, and the celebrations tied to the 1889 World's Fair in Paris, launched an era of optimism and affluence. French imperialism was in its prime. It was a cultural center of global influence, its educational, scientific and medical institutions were at the leading edge of Europe.
