Algerian Arabic language in the context of Seybouse River

Dey (Algerian Arabic: داي, from Ottoman Turkish: دایی, lit. 'uncle') was the title given to the rulers of the regencies of Algiers, Tripolitania, and Tunis under the Ottoman Empire from 1671 onwards. Twenty-nine deys held office from the establishment of the deylicate in Algeria until the French conquest in 1830.

The dey was chosen by local civilian, military, and religious leaders to govern for life and ruled with a high degree of autonomy from the Ottoman sultan. The main sources of his revenues were taxes on the agricultural population, religious tributes, and protection payments rendered by Corsairs, regarded as pirates who preyed on Mediterranean shipping. In the European part of the Ottoman Empire, in particular during its decline, leaders of the outlawed janissary and yamak troops sometimes acquired title of Dahi or Dahia, which is derived from Dey.

Guelma (Arabic: قالمة Qālima; Algerian Arabic: ڨالمة; Algerian pronunciation: Arabic pronunciation: [ɡelmæ]) is the capital of Guelma Province and Guelma District, located in north-eastern Algeria, about 65 kilometers from the Mediterranean coast. Its location corresponds to that of ancient Calama.
