Mercosur or Mercosul (Spanish: Mercado Común del Sur, Portuguese: Mercado Comum do Sul, Guarani: Ñemby Ñemuha, English: Common Southern Market) is an economic and political agreement among Argentina, Brazil, Paraguay and Uruguay. Founded in 1991 by the Treaty of Asunción, which was later amended and updated by the 1994 Treaty of Ouro Preto. Its purpose is to promote free trade and the fluid movement of goods, people, and currency. The official languages are Portuguese, Guaraní, and Spanish. It has been updated, amended, and changed many times since. It is now a full customs union. Mercosur and the Andean Community of Nations are customs unions that are components of a continuing process of South American integration connected to the Union of South American Nations.

Mercosur origins trace back to 1985 when Presidents Raúl Alfonsín of Argentina and José Sarney of Brazil signed the Argentina-Brazil Integration and Economics Cooperation Program or PICE (Portuguese: Programa de Integração e Cooperação Econômica Argentina-Brasil, Spanish: Programa de Integración y Cooperación Económica Argentina-Brasil). The program also proposed the Gaucho as a currency for regional trade.
