Zagros Mountains The Zagros Mountains (Persian: کوه‌های زاگرس‬‎; Kurdish: چیاکانی زاگرۆس‬‎) are a long mountain range in Iran, Iraq and southeastern Turkey. This mountain range has a total length of 1,600 km (990 mi). The Zagros mountain range begins in northwestern Iran and roughly follows Iran's western border, while covering much of southeastern Turkey and northeastern Iraq. From this border region, the range roughly follows Iran's coast on the Persian Gulf. It spans the whole length of the western and southwestern Iranian plateau, ending at the Strait of Hormuz. The highest point is Mount Dena, at 4,409 metres (14,465 ft).
Persian Empire Iranian dynastic history was interrupted by the Arab conquest of Persia in 651Â AD, establishing the even larger Islamic caliphate, and later by the Mongol invasion. The main religion of ancient Persia was the native Zoroastrianism, but after the seventh century, it was replaced by Islam.
