The Kurdish people compose one of the ancient nations of the Middle East. Kurdistan, the land of the Kurds, is spread among several modern states: northwestern Iran, northern Iraq, northeastern Syria, southeastern Turkey, and small parts of Armenia.
The map on that Assyrian site showed an indistinct area that seems to include some of the same upper mesopotamia, up into Turkey and over into Iran...
But I'm gathering that they're distinct from each other and that Kurds tended more to the east, while Assyrians were more to the west in that general region? Assyria centered on Nineveh, and Kurdistan from Mosul or so, eastward?
