Khwarazmshah was an ancient title used regularly by the rulers of the Central Asian region of Khwarazm starting from the Late Antiquity until the advent of the Mongols in the early 13th-century, after which it was used infrequently. There were a total of four families who ruled as Khwarazmshahs—the Afrighids (305–995), Ma'munids (995–1017), the line of Altuntash (1017–1041), and the most prominent ones, the Anushteginids (1097–1231).[1][2] Like other contemporary Central Asian titles, such as Afshin and Ikhshid, the title of Khwarazmshah is of Iranian origin.[3]
