Mercantilism presents itself as an explicit model of economic nationalism. Since its early application to the new protectionism, economic nationalism has theorized that economic activities must be subject to the maximization of the power of the state. This article aims to explain economic nationalism and track the evolution of its application, primarily to analyse its viability as a theory in the midst of economic globalization which threatens to bring about the de facto end of the state's interventionist economic system in a borderless world. As the article refutes the premise that globalization and nationalism are two sides of the same coin, national economies continue to be driven by disguised new forms of economic nationalism.
