The paper addresses the genealogies of the Musaviyya Sayyids focusing on materials of funeral epigraphy from the Shāh-i Zinda complex (15th -18th centuries). This is the first attempt on the basis of inscriptions to restore chronologically the history of the Musaviyya family, and to put forth the assumption of political functions of certain persons from this family. For the first time the texts of epitaphs and their translations into English were brought in scientific circulation. The paper opens a wide field for further research on Sayyids’ history, genealogies, and their reconstruction.
