The Persian Gulf is a mediterranean sea in Western Asia. The body of water is an extension of the Arabian Sea (Gulf of Oman) through the Strait of Hormuz and lies between Iran to the northeast and the Arabian Peninsula to the southwest.The Shatt al-Arab river delta forms the northwest shoreline.
The body of water is historically and internationally known as the "Persian Gulf". Arab governments refer to it as the "Arabian Gulf" or "The Gulf". The name "Gulf of Iran (Persian Gulf)" is used by the International Hydrographic Organization.
The Persian Gulf was a battlefield of the 1980–1988 Iran–Iraq War, in which each side attacked the other's oil tankers. It is the namesake of the 1991 Gulf War, the largely air- and land-based conflict that followed Iraq's invasion of Kuwait.
The Persian Gulf has many fishing grounds, extensive reefs (mostly rocky, but also coral), and abundant pearl oysters, but its ecology has been damaged by industrialization and oil spills.
