The most notable of these were Migrin (or Muqrin) and Mi'kal, though the name Hajr continued to appear in local folk poetry. The earliest known reference to the area by the name Riyadh comes from a 17th-century chronicler reporting on an event from the year 1590. In 1737, Deham ibn Dawwas, a refugee from neighboring Manfuha, took control of Riyadh.
