The Organisation for European Economic Co-operation (OEEC) was created in 1948. Bringing together 18 countries in Western Europe following the devastation of the Second World War, this nascent precursor to the OECD laid the foundations for lasting co-operation, shared development, and open trade that continue to this day and whose goals remain as relevant as ever 75 years later. 

The extraordinary rebuilding effort put Europe’s economy back on its feet in record time. The Marshall Plan aid ended – but the seed had been planted. Countries continued to work in partnership to share insights and best practices, to strive towards shared interests, and membership expanded to include Canada, the United States and Japan. The Convention transforming the OEEC into a new organisation was signed at the Château de la Muette in Paris on 14 December 1960. It was the beginning of a new era: the Organisation for Economic Co-operation and Development came into being on 30 September 1961.

Over the next 60 years, the OECD’s membership would grow to 38, including countries from Latin America, Asia and the Pacific, fulfilling its mission of supporting countries to find common solutions to common challenges. Through international co-operation and shared values, the OECD’s goal has been to drive forward better policies for better lives – building on the legacy of the OEEC, whose founding principles remain more relevant than ever.
