Radicaux indépendants
By the end of World War I, the Radical-Socialist Party, now led by Édouard Herriot, were generally a moderate centre-left party faced with the governmental dominance of the socially-conservative liberal parties to its right (see Independent Radicals and Democratic Alliance) and pressure from its left by the rise of support for the socialist French Section of the Workers' International (SFIO) and French Communist Party (PCF). With these political forces, Radical-Socialists shared anti-clericalism and the struggle for "social progress", but unlike the other left parties the Radical-Socialists defended the principle of strict parliamentary action and the defence of private property, at least that of smallholders and small business. Additionally, the Radical-Socialist Party had thought before 1914 that its old adversaries among the Catholic, monarchist and traditionalist right had been weakened once and for all, instead these emerged reinvigorated by World War I.
