[15] The CSV is a member of the Christian Group,[16] European People's Party, and the Centrist Democrat International.

Since the Second World War, every Prime Minister of Luxembourg has been a member of the CSV, with only two exceptions: Gaston Thorn (1974–1979), and Xavier Bettel (2013–2023).

Mostly in coalition with the Democratic Party (DP), it gave Luxembourg a certain economic and social stability.

He remained as such until 1995, when Jean-Claude Juncker became PM, with Santer meanwhile taking up the post of President of the European Commission.

Following the 2013 general election, the party went into opposition for the second time in its history as the Democratic Party's Xavier Bettel became Prime Minister in coalition with the LSAP and The Greens, making it the first time in Luxembourg's history that a three-party coalition government had been formed.
