 The most prominent of the founders was Pierre Prüm, who was appointed the party's leader.The constitutional amendments of 1919 introduced universal suffrage and proportional representation, strengthening the new populists' chance of winning both votes and seats.In the first election after the reforms, the party won three seats (out of 48) in the Chamber of Deputies, finishing a distant fourth; the dominant Party of the Right won 27 seats, allowing it to form the only stand-alone government in Luxembourgian history.
