Summary: Iran's sovereignty over the three islands of the Lesser and Greater Tunbs and Abu Musa is among controversial issues which is often being debated by certain Arab countries. This same group is also attempting for years to change the name of the Persian Gulf in southern Iran into the `Arabian Gulf'. These attempts are being made despite the fact that the term Persian Gulf has been used in the oldest historical sources, including that of the Greek historian Herodotus, over 2500 years go. Iran's sovereignty over the three islands has been also emphatically referred to in many other historical documents.

The United Nations with 22 Arab member states has on two occasions officially declared the unalterable name of the sea between Iran and the Arabian Peninsula as the Persian Gulf. The first announcement was made through the document UNAD, 311/Qen on March 5, 1971 and the second was UNLA 45.8.2 (C) on August 10, 1984.

The Latin term "Sinus Persicus" is equivalent to "Persicher golf" in French, "Persico qof" in Italian, "Persidskizalir" in Russian and "Perusha Wan" that all mean "Pars" (5).

Prior to the stationing of the Aryan Iranians on Iran's Plateau, the Assyrians named the sea in their inscriptions as the "bitter sea" and this is the oldest name that was used for the Persian Gulf (6).

An inscription of Darius found in the Suez Canal, used a phrase with a mention of river Pars which points to the same Persian Gulf.

The Greek historian Herodotus in his book has repeatedly referred to the Red Sea as the "Arab Gulf" (7).

Straben, the Greek historian of the second half of the first century BC and the first half of the first century AD wrote: Arabs are living between the Arabian Gulf and the Persian Gulf (8).

Ptolemy, another renowned Greek geographer of the 2nd century has referred to the Red Sea as the "Arabicus Sinus", i.e. the Arabian Gulf. In the book `the world boundaries from the East to the West' which was written in the 4th century Hegira, the Red Sea was dubbed as the Arabian Gulf.

Today, the most common Arabic works refer to the sea in south Iran as the "Persian Gulf", including the world famous Arabic encyclopedia `Al-Monjad' which is the most reliable source in this respect (9).

There are undeniable legal evidences and documents in confirmation of the genuineness of the term Persian Gulf. From 1507 to 1560 in all the agreements that Portuguese, Spanish, British, Dutch, French and Germans concluded with the Iranian government or in any other political event everywhere there is a mention of the name Persian Gulf (10).

Even in agreements with the participation of Arabs there is a mention of "Al-Khalij al-Farsi" in the Arabic texts and "Persian Gulf" in English texts, such as the document for the independence of Kuwait which was signed between the emir of Kuwait and representatives of the British government in the Persian Gulf.

The document, which was signed on June 19, 1961 by Abdullah As-Salem As-Sabah, has been registered in the Secretariat of the United Nations according to article 102 of the U.N. Charter and can be invoked at any U.N. office (11).

Since the beginning of the 20th century, the name "Persian Gulf" has been used in geography and history books with less reference to the "Fars Sea". Such a change has suggested the idea that the "Fars Sea" had been an old name substituted by a new term "Persian Gulf" (12)

The beginning of 1930s was a turning point in the history of efforts for changing the name of Persian Gulf when Sir Charles Bellgrave, (?) the British diplomatic envoy in Bahrain opened a file for the change in the name of the Persian Gulf and proposed the issue to the British Foreign Office. Even before the response of the British Foreign Office he used the fake name (in an attempt to retake Bahrain, the Tunbs, Abu Musa, Sirri, Qeshm, Hengam and other islands belonging to Iran and to disclose and thwart the plot of disintegration of Khuzestan) (13).

Besides all the disputes that have been made over the name of the Persian Gulf, the United Nations with its 22 Arab member countries has on two occasions officially declared the unalterable name of the sea between Iran and the Arabian Peninsula as the Persian Gulf. The first announcement was made through the document UNAD, 311/Qen on March 5, 1971 and the second was UNLA 45.8.2 (C) on August 10, 1984. Moreover, the annual U.N. conference for coordination on the geographical names has emphatically repeated the name "Persian Gulf" each year (14).

Although using the "Arabian Gulf" instead of the "Persian Gulf" has no basis and will not be accepted in any culture or language, however, it will not diminish our responsibility in expressing the reality and eliminating ambiguities as the main and oldest inhabitants of the region.

"The Greater Tunb Island is limited from north to Qeshm Island, from west to the Lesser Tunb, from south to Abu Musa and Raas al-Khaima and from east to Oman (15). The island is called the Greater Tunb, Gap Tunb, Tunb-e Mar, Greater Tunb-e Mar, etc..." (16).

In the Islamic era up to the recent centuries the Greater Tunb Island was part of the states of Fars, Kerman, Mokran and Hormuzgan.

In 1884 it was part of the Persian Gulf ports.
In 1949 together with 29 other islands it was a village under the district of Lengeh.
In 1951, it was part of the village Mazdouqi in Lengeh district of the city of Lar.
In 1954, it was a village in Abu Musa district of Bandar Lengeh port city.
In 1958, Abu Musa and Great Tunb districts jointed together and formed a large district with Kish Island as its center.
In 1976, it became part of the city of Kish.
In 1982, it became part of the city of Abu Musa.
In 1991, the Great Tunb Island was part of the Tunb district of the city of Bu Musa (17).

The Greater Tunb Island due to its far distance from the Strait of Hormuz has no strategic importance by itself. However, given Iran's strategic situation, it is considered an important link in the defensive line of Iran in the Strait of Hormuz (18).

The Lesser Tunb Island is neighboring the city of Lengeh in the north, Abu Musa Island in the south, the Greater Tunb Island in the east and Faroo and Faroogan islands in the west. The island is rectangular in shape (19).
