Gaullism is a French political ideology based on the thought and action of Charles de Gaulle. The main axis of de Gaulle's international policies was national independence, with, as some practical consequences, some reluctance for international organizations such as NATO or the European Economic Community. The basic tenets were that France should not have to rely on any foreign country for its survival (thus the creation of the French nuclear deterrent) and that France should refuse subservience to any foreign power, be it the United States or the Soviet Union.
One may also cite social conservatism, and economic dirigisme as parts of the Gaullist ideology, but these are not necessarily accepted by those who called themselves Gaullists. Gaullism has sometimes been characterized as a form of populism, since de Gaulle relied heavily on his personal charisma.
There are people on the Left who also call themselves Gaullists. Even François Mitterrand, who denounced de Gaulle's way of ruling as a permanent coup d'état, was very intent on keeping the nuclear deterrent and asserting France's independence.
The main policies of grandeur — that is, the insistence that France is a major power in the world scene and the establishment of military and economic forces to back this claim.
The first logo of the RPR recalls the Gaullist inheritance with the Cross of Lorraine, symbol of the Free French, drawn on top of the phrygian cap (normally worn by Marianne).
