 The sultanate was later conquered by the Songhai Empire in 1500.
 After the defeat of Songhai in 1591, the Agadez Sultanate regained its independence.

 Culturally, the Igdalen are often considered a Tuareg faction.
 In the past they have formed a sub-confederation with the Kel Fadey, Kel Ferwan and others in the Kel Ayr Tuareg confederation or "Drum Group".
The Sawaq language (Tuareg name: "Tasawaq"), sometimes also called "Ingelshi", is a northern Songhay language spoken by the "Issawaghan" (or "Ingalkoyyu"), a community surrounding Ingal in Niger.

 Dazaga is spoken by around 380,000 people, primarily in the Djurab Desert region and the Borkou region, locally called Haya or Faya-Largeau northern-central Chad, the capital of the Dazaga people.
 Dazaga is spoken in the Tibesti Mountains of Chad (330,000 speakers), in the eastern Niger near N'guigmi and to the north (50,000 speakers).
 It is also spoken to a smaller extent in Libya and in Sudan, where there is a community of 3,000 speakers in the city of Omdurman.
 There's also a small diaspora community working in Jeddah, Saudi Arabia.
 The two primary dialects of the Dazaga language are Daza and Kara, but there are several other mutually intelligible dialects, including Kaga, Kanobo, Taruge and Azza.
