The pilgrimage to Mecca, or Hajj, is a unique aspect of Islam. It is also a remarkable logistic feat for the Saudi Kingdom. How does this annual event combine with the transformations of the modern world? In this short book the author charts the changes that have altered the Hajj from the ancient camel caravans to the contemporary motorised and air conditioned pilgrimage it is today. Looking at historic accounts, politics, health, transportation, and the experiences of Muslims living in Britain, this work provides a nuanced overview of the contiguity of the Hajj. This book is an excellent introduction to the broad scope of issues that Hajj studies entail. It is of interest to those curious about the pilgrimage, and an asset to specialists with its rich array of sources and interpretation.
