Only in 1911 did Versailles definitely recover its level of population of 1789, with 60,458 inhabitants at the 1911 census. In 1919, at the end of the First World War, Versailles came into the limelight again as the various treaties ending the war were signed in the castle proper and in the Grand Trianon. After 1919, as the suburbs of Paris continued to expand, Versailles was absorbed by the urban area of Paris and the city experienced a strong demographic and economic growth, turning it into a large suburban city of the metropolitan area of Paris. The role of Versailles as an administrative and judicial center has been reinforced in the 1960s and 1970s, and somehow Versailles has become the main center of the western suburbs of Paris.
