This article discusses a story that has enjoyed a long life in scholarly literature, drama, and the visual arts: the alleged caging of the Ottoman Sultan Bayezid I Yildirim (r. 1389–1402) by the Central Asian conqueror, Temür (r. 1370–1405). Attention is focused on the evolution of scholarly discourse on the existence (or otherwise) of the cage. The period from the late seventeenth to the first half of the twentieth century is looked at in particular detail. The debate around the captivity of Bayezid is only fully understood when it is located within a larger historical framework, namely the changing political relationships between Christian Europe and the Ottoman Empire from the fall of Constantinople in 1453 until the nineteenth century.
