Nationalism is frequently associated with the break-up of states. This article seeks to demonstrate that nationalism, through the guise of bi-nationalism, can be compatible with the creation and maintenance of a multinational state. The political vision of the Nationalistes of Que´bec provides the focus. In the early twentieth century these individuals believed that Canada could emulate states such as Switzerland and Belgium, which were marked by a degree of power-sharing. They sought the adoption of practices which have since become associated with the doctrine of 'consociationalism'. The research suggests that these nationalists were conscious that federalism, on its own, is not sufficient to accommodate a significant national minority.
