By Reva Bhalla At the edge of empires lies Kurdistan, the land of the Kurds. The jagged landscape has long been the scene of imperial aggression. For centuries, Turks, Persians, Arabs, Russians and Europeans looked to the mountains to buffer their territorial prizes farther afield, depriving the local mountain dwellers a say in whose throne they would ultimately bow to. The hot temperament of this borderland was evident in an exchange of letters between Ottoman Sultan Selim I and Safavid Shah Ismail I shortly before the rival Turkic and Persian empires came to blows at the 1514 Battle of Chaldiran in northern Kurdistan.
