History of Persian Gulf :

The Persian Gulf has a rich history that dates back to ancient times. The Achaemenid Empire established the first Persian Empire in Pars (Persis, or modern Persia) in the southwestern region of the Iranian Plateau in 330 BC. As a result, the body of water in the border of this province became known as the Persian Gulf. The Persian Gulf Basin is a wedge-shaped foreland basin that lies beneath the western Zagros thrust and was created as a result of Collisions between the Arabian and Eurasian plates. The current flooding of the basin began 15,000 years ago due to the rising sea level of the Holocene Glacial Retreat 3. During the colonial period, Portuguese influence in the Persian Gulf lasted for 250 years. In modern times, the Persian Gulf has been a battleground for various conflicts.
