The pilgrimage as a religious duty was a difficult, dangerous and sometimes irreversible journey, and it was accompanied with many problems. At the time of the Seljuk rule in Iran (429 -590 BC), on the one hand sometimes the difficult economic conditions affected the pilgrimage and on the other hand, the pilgrims were faced with many problems including the insecurity caused by the marauding Bedouin Arabs, Isma'ilis’ sudden attacks, lack of food and water, famine and deadly diseases like Cholera. Political differences such as the differences among the Seljuk sultans, some of the Iraqi Emirs’ sence of independence, and the differences between the Emirs of Mecca with the head of the pilgrimage (Emir Al-Hojaj), would increase the problems of the pilgrims. This article uses historical reports to investigate the obstacles on the way of pilgrimage in the Seljuk period implementing a descriptive-analytic approach.
