Central Asia is commonly imagined as the marginal land on the periphery of Chinese and Middle Eastern civilisations. At best, it is understood as a series of disconnected areas that served as stop-overs along the Silk Road. However, in the mediaeval period, this region rose to prominence and importance as one of the centres of Persian-lslamic culture, from the Seljuks to the Mongols and Timur.
