Autarky in the context of "Fascist Italy (1922–1943)"

The Kingdom of Italy was governed by the National Fascist Party from 1922 to 1943 with Benito Mussolini as prime minister transforming the country into a totalitarian dictatorship. The Fascists crushed political opposition, while promoting economic modernization, traditional social values and a rapprochement with the Roman Catholic Church. They also promoted imperialism, resulting in the expansion of the Italian Empire.

According to historian Stanley G. Payne, "[the] Fascist government passed through several relatively distinct phases". The first phase (1922–1925) was nominally a continuation of the parliamentary system, albeit with a "legally-organized executive dictatorship". In foreign policy, Mussolini ordered the pacification of Libya against rebels in the Italian colonies of Tripolitania and Cyrenaica (eventually unified in Italian Libya), inflicted the bombing of Corfu, established a protectorate over Albania, and annexed the city of Fiume into Italy after a treaty with the Kingdom of Yugoslavia. The second phase (1925–1929) was "the construction of the Fascist dictatorship proper". The third phase (1929–1935) saw less interventionism in foreign policy. The fourth phase (1935–1940) was characterized by an aggressive foreign policy: the Second Italo-Ethiopian War, which was launched from Eritrea and Somaliland; confrontations with the League of Nations, leading to sanctions; growing economic autarky; the invasion of Albania; and the signing of the Pact of Steel. The fifth phase (1940–1943) was World War II itself, ending in military defeat, while the sixth and final phase (1943–1945) was the rump Salò Government under German control.

Comparative advantage in an economic model is the advantage over others in producing a particular good. A good can be produced at a lower relative opportunity cost or autarky price, i.e. at a lower relative marginal cost prior to trade. Comparative advantage describes the economic reality of the gains from trade for individuals, firms, or nations, which arise from differences in their factor endowments or technological progress.

David Ricardo developed the classical theory of comparative advantage in 1817 to explain why countries engage in international trade even when one country's workers are more efficient at producing every single good than workers in other countries. He demonstrated that if two countries capable of producing two commodities engage in the free market (albeit with the assumption that the capital and labour do not move internationally), then each country will increase its overall consumption by exporting the good for which it has a comparative advantage while importing the other good, provided that there exist differences in labor productivity between both countries. Widely regarded as one of the most powerful yet counter-intuitive insights in economics, Ricardo's theory implies that comparative advantage rather than absolute advantage is responsible for much of international trade.

Self-sustainability and self-sufficiency are overlapping states of being in which a person, being, or system needs little or no help from, or interaction with others. Self-sufficiency entails the self being enough (to fulfill needs), and a self-sustaining entity can maintain self-sufficiency indefinitely. These states represent types of personal or collective autonomy. A self-sufficient economy is one that requires little or no trade with the outside world and is called an autarky.

Economic nationalism or nationalist economics is an ideology that prioritizes state intervention in the economy, including policies like domestic control and the use of tariffs and restrictions on labor, goods, and capital movement. The core belief of economic nationalism is that the economy should serve nationalist goals. As a prominent modern ideology, economic nationalism stands in contrast to economic liberalism and economic socialism.

Economic nationalists oppose globalization and some question the benefits of unrestricted free trade. They favor protectionism and advocate for self-sufficiency. To economic nationalists, markets are to be subordinate to the state, and should serve the interests of the state (such as providing national security and accumulating military power). The doctrine of mercantilism is a prominent variant of economic nationalism. Economic nationalists tend to see international trade as zero-sum, where the goal is to derive relative gains (as opposed to mutual gains).

The Greater East Asia Co-Prosperity Sphere (Japanese: 大東亜共栄圏, Hepburn: Dai Tōa Kyōeiken), also known as the GEACPS, was a pan-Asian union that the Empire of Japan tried to establish. Initially, it covered Japan (including annexed Korea), Manchukuo, and China, but as the Pacific War progressed, it also included territories in Southeast Asia and parts of India. The term was first coined by Minister for Foreign Affairs Hachirō Arita on June 29, 1940.

The proposed objectives of this union were to ensure economic self-sufficiency and cooperation among the member states, along with resisting the influence of Western imperialism and Soviet communism. In reality, militarists and nationalists saw it as an effective propaganda tool to enforce Japanese hegemony. The latter approach was reflected in a document released by Japan's Ministry of Health and Welfare, An Investigation of Global Policy with the Yamato Race as Nucleus, which promoted racial supremacist theories. Japanese spokesmen openly described the Greater East Asia Co-Prosperity Sphere as a device for the "development of the Japanese race." When World War II ended, the Greater East Asia Co-Prosperity Sphere became a source of criticism and scorn for the Allies.
