The latest events that mark contemporary history, such as the wars in Ukraine and the Middle East, as well as the emergence of new forms of nationalism in the United States and Europe, worry – even “stun” – citizens. These events are widely commented on by the media and social networks, but are also analyzed by researchers, who strive to find the keys to understanding them by drawing on economic and social theories. Karl Polanyi (1886-1964), in his major work entitled The Great Transformation published in 1944, puts forward an explanation that is likely to answer these questions.
