For the Netherlands and Belgium in the twentieth century, occupation is a key concept to understand the impact of the war on welfare state development. The occupation shifted the balance of power between domestic social forces: this was more decisive for welfare state development than the action of the occupier in itself. War and occupation did not result exclusively in more cooperation between social classes: some interest groups saw the war as a window of opportunity to develop strategies resulting in more social conflict. Class cooperation was often part of a political strategy to gain control over social groups or to legitimate social reforms. The world wars changed the scale of organization of social protection, from the local to the national level: after World War II social policy became a mission for the national state. For both countries, war endings had more lasting effects for welfare state development than the occupation itself.
