General elections were held in Luxembourg on 21 October 1945. They were the first elections held after the German occupation during World War II. As a result of the war, the political alliances of the interwar period had been ended. In their place were new parties; the Christian Social People's Party, the Luxembourg Socialist Workers' Party, and the Patriotic and Democratic Group in place of the Party of the Right, Socialist Party, and Radical Liberal Party respectively. It is regarded as a realigning election, as the election established the party political order, with four established parties, that would be maintained until 1974.
