Extending below the 38th parallel, immersed in a luxuriant nature made of deep gorges and steep mountain heights, South Korea has known, starting from the political division that made it independent from the rest of the peninsula and the devastation of war which resulted from a development process characterized by various factors: alternating political events (regimes endorsed under the aegis of US interests, military dictatorships, corrupt and repressive governments but also intense democratic pressures on the part of the people); economic changes (from an agricultural vocation made up of debts and backwardness to an intense and rapid industrialization as well as the opening of markets); social transformations (impoverishment of peasants, forced urban emigration, exploitation of cheap labor, unionization, but also widespread literacy) and fluctuations in international relations (trade and commercial agreements with Western partners but also delicate diplomatic issues, such as the one with Japan, accused of historical revisionism). South Korea appears today as a growing country, committed to consolidating the economic achievements that have characterized the past decades and opening up new spaces for a market that is increasingly looking towards Western models. Also on the international level, South Korea has shown its willingness to resolve the delicate issue of reunification with the rest of the peninsula, through a political confrontation (the summit held at the end of the nineties between the leaders of the two countries is historic).
