Sanandaj to Tabriz, Iran
The words “Kurdistan” and “Azerbaijan” typically don’t bring Iran to mind. Kurds are often associated with separatist movements in the countries they live in: Turkey (where the Kurdish Worker’s Party, or PKK, engage in acts of terrorism), Syria, and Iraq (where there’s already the autonomous Iraqi Kurdistan region). Azerbaijan… well, they already have a country to the north of Iran.
To my pleasant surprise, both of these minority groups seem generally happy as part of Iran. (There is still a Kurdish movement for autonomy/independence and incidents of violence, but much smaller than those of neighbouring countries.) Locals are as nice as always as in the rest of Iran, if not nicer, and as much as I heard “welcome to Kurdistan” and “welcome to Azerbaijan,” from my experience, they’d happily add “welcome to Iran!” in the same breath.
