[1] In 1821, Ismail Kamel Pasha, the son of Muhammad Ali Pasha, during his invasion to Sudan, sent his ally the leader of the Mirbab tribe, Nasr al-Din al-Sadig, from the city of Berber to Ad-Damar, to urge the elders (Almajazeeb) of the city to offer loyalty to the new ruler of the country.

The relationship between the elders of the Damer (Almajazeeb) and the Turkish-Egyptian government improved, even more, when General Gordon Pasha arrived in Sudan, where he was welcomed by them.

Sheikhs in Ad-Dāmar supported the Mahdia revolution and they did albaia (the promise) to Khalifa Abdullah Altaeshi and chose to stand by their side in the war against the Turkish rule and engaged in various sites of jihad.

Ad-Damir has a hot desert climate (Köppen: BWh)[2] characterized by consistently high temperatures, minimal precipitation, and low humidity.
