The most notable difference is that, contrary to other European heraldic systems, the Jews, Muslim Tatars or another minorities would be given the noble title. Also, most families sharing origin would also share a coat-of-arms. They would also share arms with families adopted into the clan (these would often have their arms officially altered upon ennoblement). Sometimes unrelated families would be falsely attributed to the clan on the basis of similarity of arms. Also often noble families claimed inaccurate clan membership. Logically, the number of coats of arms in this system was rather low and did not exceed 200 in late Middle Ages (40,000 in the late 18th century).
