According to Iranian photographer and author Peyman Hooshmandzadeh, When you are with Turkmens, you need to be a little more careful; after all, you are a stranger. Over a period of sixteen years, he has repeatedly visited the area in north-eastern Iran where these tribal people of nomadic heritage live, wedged between the Caspian Sea, a desert and a mountain range, and documented the modern Turkmen way of life and customs. Traditionally a prominent horse culture, their lifestyle is heavily invested in horsemanship, which has seen a resurgence in the years following the Soviet collapse. These images beautifully capture aspects of this reticent and unique people.
