This trend inside the Walloon Movement is the youngest. It was born during the Second World War, in the Walloon Democratic and Socialist Rally ("Rassemblement démocratique et socialiste wallon" – RDSW), a group mainly from Liège which arose at the end of 1942. It grouped together politicians and Walloon militants. The RDSW's attempt to create a unique party for the left was without success. It also aimed to be a working group, in which the liberal Fernand Schreurs and the socialist Fernand Dehousse take part, on the future statute of Wallonia. The independence manifesto was written in November 1943, after the departure of the federalists, in the form of a draft Constitution for a Walloon republic. Its principle rests on "the formation of an independent Walloon State, suitable to be associated with a Flemish State and a State of Brussels, but integrated in the defensive system of France".
