Out of all Caucasian rug schools. Kazak seems to be the most varied and stretching across various ethnic groups.

That is not to say that other schools a more ethnically homogenous but the Kazak school of Caucasian rugs includes works by Georgian and Armenian Christians and Azeri Turkic Muslims spanning the territories of 3 present-day countries, formerly Soviet republics.
It is perhaps, and this is an invitation to a group discussion, it is because while other groups are easier to categorize as they share similarities in structure, design and material, Kazaks are those Caucasian rugs that somehow elude classification and, incidentally, constitute the most interesting Caucasian textile artifacts group.
