Although Burton was certainly not the first non-Muslim European to make the "Hajj" (Ludovico di Varthema did this in 1503 and Johann Ludwig Burckhardt in 1815), his pilgrimage is the most famous and the best documented of the time. He adopted various disguises including that of a Pashtun to account for any oddities in speech, but he still had to demonstrate an understanding of intricate Islamic traditions, and a familiarity with the minutiae of Eastern manners and etiquette. Burton's trek to Mecca was dangerous, and his caravan was attacked by bandits (a common experience at the time). As he put it, though "... neither Koran or Sultan enjoin the death of Jew or Christian intruding within the columns that note the sanctuary limits, nothing could save a European detected by the populace, or one who after pilgrimage declared himself an unbeliever". The pilgrimage entitled him to the title of Hajji and to wear the green head wrap. Burton's own account of his journey is given in "A Personal Narrative of a Pilgrimage to Al-Madinah and Meccah".
