The 20th century was a time of vast change for Paris, marked by two World Wars, a cultural boom, and considerable urban development. Here are some of the key events and developments that shaped Paris during this period:

World War I (1914-1918): Paris played a significant role in World War I as a strategic center and morale booster for the Allies. Though it escaped major physical damage, the war’s social and psychological effects were significant.

Interwar Period: Between the two World Wars, Paris was a hub for artists, writers, and intellectuals from around the world. This era, known as the “Années Folles” (Crazy Years), saw cultural movements like Dadaism and Surrealism flourish. The city became a melting pot of creativity and innovation with influential figures like Ernest Hemingway, Gertrude Stein, Pablo Picasso, and Salvador Dalí making it their home.

1924 Summer Olympics: Paris hosted the 1924 Summer Olympics, a significant event that showcased the city on the international stage.

World War II (1939-1944): Paris was occupied by German forces in 1940, marking the beginning of a dark chapter in its history. The city was liberated by the Allies in August 1944.

Post-War Reconstruction and Development: After the war, Paris underwent extensive reconstruction and development. Important architectural projects from this period include the UNESCO headquarters (1958), the Tour Montparnasse (1973), and the Centre Georges Pompidou (1977).

May 1968 Protests: Widespread protests erupted in May 1968, initially led by students demanding educational reform. The movement grew into a broader societal uprising, with strikes and demonstrations involving millions of people.

Late 20th Century Urban Projects: Significant urban development projects were undertaken in the late 20th century. These include the creation of the business district La Défense, the opening of the Parc de la Villette, and the establishment of the Musée d’Orsay and the Institut du Monde Arabe.

Rise of Modern Architecture: Notable additions to the Parisian skyline in the late 20th century include the controversial glass pyramid at the Louvre (1989) and the Grande Arche in La Défense (1989).
