Alexandre Millerand was a French politician. He was Prime Minister of France from 20 January to 23 September 1920 and President of France from 23 September 1920 to 11 June 1924. His participation in Waldeck-Rousseau's cabinet at the start of the 20th century, alongside the Marquis de Galliffet, who had directed the repression of the 1871 Paris Commune, sparked a debate in the French Section of the Workers' International (SFIO) and in the Second International about the participation of socialists in bourgeois governments.

Pierre Marie René Ernest Waldeck-Rousseau was a French Republican politician who served for three years as the Prime Minister of France.
