The Persian Gulf, in the Southwest Asian region, is an extension of the Indian Ocean located between Iran and the Arabian Peninsula. The Persian Gulf was the focus of the Iraq-Iran War that lasted from 1980 to 1988, with each side attacking the other's oil tankers. In 1991, the Persian Gulf again was the background for what was called the Persian Gulf War or the "Gulf War" when Iraq invaded Kuwait and was subsequently pushed back, despite the fact that this conflict was primarily a land conflict.
