Origins Prior to the 1630s, the region was ruled by the
Tunjur kingdom, established around the 15th century. The Arab migrants to the area for trade which became Wadai claimed to be descendants of the
Abbasid Caliphs, specifically from
Salih ibn Abdallah ibn Abbas. Yame, a Maba leader brought Islam to their people after he himself embraced Islam, Arab migrants settled in
Debba, near the future capital of
Ouara (Wara). Abd al-Karim secured and centralized his power in the area by marrying the Tunjur King Daud's daughter, Meiram Aisa, and then forming other marriage pacts with local dynasties and tribes, such as the
Masalit and
Dajo tribes. Abd al-Karim built his capital at Wara and founded the Kolak dynasty, and made Islam the state religion despite most commoners following
traditional religions. After Abd al-Karim's death, Wadai's history was marked by civil wars and hostile relations with
Bornu and
Darfur. Wadai's wealth came from
slave trading and the procurement of slaves in raids. Under Ya'qub's rule Wadai suffered a terrible drought. Ya'qub's son, Joda, expanded the state southwards and into the Tunjur heartland of
Mondo. Sabun further extended his rule south to
Dar Sila and
Dar Runga. Around 1809/10 a new trade route to the north was found by a traveller from
Jala, linking
Ennedi,
Kufra and
Jalu-
Awjila to
Benghazi, and Sabun outfitted royal caravans to take advantage of it. This freed Wadai from being economically dependent on Bornu and Darfur.
Colonial period and post-independence The Wadai Sultanate was reconstituted under French suzerainty in 1935, with
Muhammad Urada ibn Ibrahim becoming
Kolak, or sultan. It became a part of the independent
Republic of Chad on the day of the country's independence in 1960. The sultanate continues to exist as a
non-sovereign monarchy in Chad and its current
Kolak since 2019 is
Cherif Abdelhadi Mahdi. Unrelated to his predecessor who had been suspended, Mahdi was appointed by the Chadian government, which many viewed as interference in tradition. In January 2022 the government suspended the sultan's powers, igniting protests, however they were regranted in April 2023. == Military ==
