The Kingdom received its name from the fortified port city which served as its capital. It was one of the most important ports in the Middle East at the time as it controlled seaway trading routes through the Persian Gulf to China, India, and East Africa. This port was originally located on the southern coast of Iran to the east of the Strait of Hormuz, near the modern city of Minab, and was later relocated to the Island of Jarun which came to be known as Hormuz Island, which is located near the modern city of Bandar-e Abbas.
