“ At this day, in some parts of Persia, e.g. Azerbaijan, Turks make the bulk of the population besides supplying the reigning dynasty of the whole kingdom. For the Shahs of the Kajar house are not Iranian, but purely Turkish. This, it should be observed, was the western limit of Turkish expansion in the mass. Azerbaijan is the nearest region to us in which Turki blood predominates, and the westernmost province of the true Turk homeland. All Turks who have passed thence into Hither Asia have come in comparatively small detachments, as minorities to alien majorities. ”
