Mosley first presented his idea of Europe forming a single state in his book "The Alternative" in 1947. He argued that the traditional vision of nationalism that had been followed by the various shades of pre-war fascism had been too narrow in scope and that the post-war era required a new paradigm in which Europe would come together as a single state. He rejected any notion of a federal Europe, instead calling for full integration. Indeed, Mosley insisted that a supranational European state was essential to the plan. The policy was presented to the wider electorate in October 1948 when Mosley called for elections to a European Assembly as the first step towards his vision.
