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).
Zoroastrianism With possible roots dating back to the second millennium BCE, Zoroastrianism enters recorded history in the 5th-century BCE.[3] Along with a Mithraic Median prototype and a Zurvanist Sassanid successor, it served as the state religion of the pre-Islamic Iranian empires for more than a millennium, from around 600 BCE to 650 CE. Zoroastrianism was suppressed from the 7th century onwards following the Muslim conquest of Persia of 633–654.[6] Recent estimates place the current number of Zoroastrians at around 190,000, with most living in India and in Iran; their number is declining.[7][8][9][circular reference][3][n 2] In 2015, there were reports of up to 100,000 converts in Iraqi Kurdistan.[10] Besides the Zoroastrian diaspora, the older Mithraic faith Yazdânism is still practised amongst Kurds.[n 3]
