Although Burton was not the first non-Muslim European to make the Hajj (that distinction belonging to Ludovico di Barthema in 1503), his pilgrimage is the most famous and the best documented of the time. He adopted various disguises, including that of a Pathan, to account for any oddities in speech, but he still had to master intricate Islamic ritual, and the minutiae of Eastern manners and etiquette. Burton's trek to Mecca was quite dangerous and his caravan was attacked by bandits (a common experience at the time). As he put it, although "...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 a green turban. Burton's own account of his journey is given in "Personal Narrative of a Pilgrimage to Al Madinah and Meccah" (1855).
