Jean-Marc Lieberherr examines Jean Monnet’s vital role in securing US arms for Britain and France during the Second World War and in driving international cooperation.

A committed internationalist, long before becoming one of the founding fathers of the EU, Jean Monnet played a crucial role in enabling cooperation between countries in two world wars. As a member of the Executive Committee of the Allied Maritime Transport Council during the First World War, he helped coordinate shipping between the Allied powers of France, Great Britain, Italy and, from 1918, the US, before becoming the Deputy Secretary General of the League of Nations in 1919.

During the subsequent world conflagration, , Monnet, trusted by Winston Churchill and Charles de Gaulle, coordinated arms procurement from the US through the Anglo-French Co-Ordinating Committee, the British Purchasing Committee and the Combined Production and Resources Board. According to economist John Maynard Keynes, Monnet’s work shortened that war by one year.

After 1945, Monnet continued seeking internationalist solutions, connecting the French and German markets under the European Coal and Steel Community. Seeing how the principles of cooperation could be applied more broadly, he advocated for a European Defence Community during the Korean War. While this attempt at European defence integration failed, his work inspired the founding treaties of the EU. He became the first ‘Honorary Citizen of Europe’ in 1976.

Jean-Marc Lieberherr is the founding chairman of the Jean Monnet Institute (JMI), which is devoted to promoting Monnet’s historical heritage. Before creating the JMI in 2021, he had a career with large international groups such as LVMH, Unilever and Rio Tinto.
