I
Historically, the ruler or monarch of a Mongol tribe.
Early on a distinction was made between the title of khan and that of khākān , or "great khan." Later the term khan was adopted by the Khwārezm-Shāh dynasties as a title for the highest nobility. Gradually it became an affix to the name of any Muslim property owner. Today it is often used as a surname.
