The princes and mirzas Yusupovy in Russia from the XVI century to the first half of the XVIII century (preliminary results)
The article attempts to combine all the currently available scattered information on the genealogy of the princes / mirzas Yusupovy in Russia of the XVI-XVIII centuries. It is concluded that the well-established idea of the only one existing branch of the family in the XVIII-XIX centuries is erroneous. However, in the first half of the XVIII century there actually was a so-called “bottleneck”, drastically reducing the number of simultaneously living representatives of the family. The reasons for this are still unknown, but such a phenomenon is typical for many princely families of Eastern origin.
