Three contributions of French culture to the world are French wine, separation of church and state in government, and high fashion. Many of the contributions are tied to France's unique history dating back to the inception of the nation.
French wine has long been considered a premium product in the world, and the country's wine culture came into fashion during Roman rule of the Gaole providence. The French wine industry has endured and shaped the world's wine-making techniques. For example, using a barrel for aging wine is a French innovation.
Another contribution is the idea of keeping religious principles and leaders out of government law. In 1905, France passed a law codifying separation of church and state and emphasizing religious neutrality of the state.
High fashion is another French contribution. Paris is internationally known for haute couture fashion and is the headquarters for many high-end fashion houses.
