Marx was forced to exit Paris by the French government in 1845, with Brussels, Belgium his next destination.[9] Despite his departure from France, he continued to see Proudhon as a potential political collaborator, asking him in 1846 to participate in a new international correspondence committee patterned after the London-based Workers' Educational Association, designed to propagate socialist ideas among the working class of continental Europe.[9] Proudhon responded cautiously to Marx's appeal.[10] Perhaps partially in consequence, Marx and his friend and political associate turned their organizing efforts to an established political body, the League of the Just.[9]
