The city of Doha was formed seceding from another local settlement known as Al Bidda. The earliest documented mention of Al Bidda was made in 1681, by the Carmelite Convent, in an account which chronicles several settlements in Qatar. In the record, the ruler and a fort in the confines of Al Bidda are alluded to. Carsten Niebuhr, a German explorer who visited the Arabian Peninsula, created one of the first maps to depict the settlement in 1765 in which he labelled it as 'Guttur'.
