Qeshm Island is situated to the north of Hormoz Strait, and the city of Qeshm is located in the southeast of this Island. This region has a warm and humid climate and is somewhat a lengthy island. During the Mongol conquest, a tribe known as Turan were the inhabitants of this island and were responsible for its prosperity. In the year 1507 AD. the Portuguese came ashore on this island and fortified themselves from the military point of view, remaining thus till the reign of Shah Abbas Safavid. In 1645 AD. the Dutch brought about an important military force in the Persian Gulf and occupied the Qeshm castle on the pretext that the Iranians had failed to abide by the trading pact. But the heat of this island compelled the Dutch to leave the place.
On the death of Nader Shah in 1747 AD., the influence of Iran in the Persian Gulf weakened, and the Javasem (Arab) tribe increased their supremacy in the vicinity, thereby conquering the Qeshm Island in the year 1760 AD. Britannia founded its naval base in the village of Basaeidoo in the Qeshm Island in the year 1882 AD., but were forced to leave this area due to climatic conditions, i.e., the heat. After the Islamic revolution, Qeshm regained its importance and in the year 1989 accounted for the second ranking economically free port. In 1990 it facilitated custom services and played an active role in this connection in the Persian Gulf and Oman Sea, both in the industry and commercial circles. Thereby further improving trade relations between Iran and other neighboring countries.
