Many scholars claim that the world has had many ‘renaissances’ in its long history: they advocate what we could call the ‘multiple renaissances’ thesis. In this article, I will focus on the history of this idea. Where and when did the ‘multiple renaissances’ thesis emerge? What intellectual exchanges and historical conditions made it possible? To answer these questions, I will first draw up a short genealogy of the idea that the European/Italian Renaissance is a ‘culture’ or a ‘social type’; then, I will show that such typological use of the renaissance made it possible to apply this concept to different historical and social configurations, not only within, but also outside Europe; finally, through an analysis of the relation between Arnold Toynbee and Hu Shi, I will show that the uses of the renaissance category in the non-European world, especially in East Asia, contributed to shaping the ‘multiple renaissances’ thesis and, through it, to redefining the perception of the renaissance in Europe proper.
