The Mouvement Souveraineté-Association (MSA, English: Movement for Sovereignty-Association) was a separatist movement formed on November 19, 1967 by René Lévesque to promote the concept of sovereignty-association between Quebec and the rest of Canada. From October 11 to 14, the MSA held its first national congress in Quebec City. The merger of the MSA and the RN created the Parti Québécois (PQ). MSA leader René Lévesque was elected president of the PQ, and RN leader Gilles Grégoire became vice-president.
