The European Free Trade Association (EFTA) is an intergovernmental organization that promotes free trade between its member states. It was founded in 1960 by seven countries: Austria, Denmark, Norway, Portugal, Sweden, Switzerland, and the United Kingdom. The UK left EFTA in 1973 to join the European Economic Community (EEC), which later became the European Union (EU).

EFTA’s main objective is to promote free trade between its member states. It does this by negotiating free trade agreements with other countries and by providing a forum for discussion and cooperation on trade-related issues. EFTA also provides technical assistance to its member states on trade-related matters.

EFTA is a smaller organization than the EU, but it has played an important role in promoting free trade in Europe. It has also been a model for other regional trade agreements, such as the North American Free Trade Agreement (NAFTA) and the Trans-Pacific Partnership (TPP).
