Given the important role that the Portuguese played in the Persian Gulf from 1507 to 1720, knowing what is available about their activities in this area is not only of importance to those interested in the history of Portugal, but also of those interested in the history of Bahrein, Iran, Iraq, Oman, Qatar, eastern Saudi Arabia and the United Arab Emirates. This bibliography of printed published works therefore contains a full list of primary and secondary sources, not only in Western languages, but also in Persian, Arabic and Turkish. It aims to facilitate the work of scholars and students, but also of the non-specialist, i.e. those among the general public who want to know more about this part of the world during the sixteenth and seventeenth centuries and about the activities of the Portuguese. Although other bibliographies exist that include the activities of the Portuguese in the Persian Gulf, all are in need of updating, and none are as comprehensive as this bibliography.
