Iran unveils historical maps to prove name of Persian Gulf

Iran has unveiled a collection of historical maps, some printed in Arab states, in an attempt to prove the legitimacy of calling its strategic sea the Persian Gulf, a reaction to the use of the term "Arabian Gulf" in the new world atlas by National Geographic publications.

Last month, Iran banned the sale of National Geographic Society publications to protest against the "Arabian Gulf" inclusion.

The issue has also caused widespread protests by Iranian intellectuals, historians, students and expatriate Iranians.

Foreign Minister Kamal Kharrazi, who inaugurated the exhibition of ancient and historical maps, said the name of the Persian Gulf could not be changed.

"Presenting historical evidences here is merely for the sake of reiteration," he said.

National Geographic said it recognised Persian Gulf as the primary name but used Arabian Gulf alongside it to make is easier for users searching for that designation.
