This paper is an attempt to reconstruct the ideas of the Arabian astronomer, mathematician, and geographer of the 1st half of the 9th c. Abu Ja'far Muhammad ibn Musa al-Khwarizmi of the Azov Sea with its adjoining areas and population. The research is based on the following basic methodological approaches: selection, systematization and analysis of the information on the region contained in the geographical work of this author “Kitab surat al-ard (book of the form of the earth). To reveal the degree of reliability of the information under investigation, a methodological principle of complexity, i.e. comparison of the evidence contained in al Khwarizmi's work with the archaeological data, has been used in studying this historical written record.
