The Carpet Wars - from Kabul to Baghdad: A Ten-Year Journey along Ancient Trade Routes by Christopher Kremmer

Going across the middle east through rugged terrain and war zones, culture and carpets are a common thread along with hard life, hate, history, and religion. Tribes and migrations and dominating chiefs and trade routes and rules of hospitality and cruelty and revenge. Every place he goes is full of interest. He travels in the footsteps of similar treks by others such as Byron (see above). I didn't know Iran was named for an Aryan migration.
