Khoja or Khwaja, a Persian word literally meaning 'master' or ‘lord’, was used in Central Asia as a title of the descendants of the noted Central Asian Naqshbandi Sufi teacher, Ahmad Kasani (1461–1542) or others in the Naqshbandi intellectual lineage prior to Baha al-din Naqshband. The most powerful religious figure in the late Timurid era was the Naqshbandi Shaykh Khwaja Ahrar. The Khojas often were appointed as administrators by Mongol rulers in the Altishahr or present-day region of Tarim Basin in Xinjiang, China.
