Mbacké is a city in central Senegal, located 190 km (118 mi) east of Dakar. It is the capital of an administrative department in the Diourbel region. Along with the near-by city of Touba, Mbacké forms an urban conurbation whose population currently stands at about 500,000, making it Senegal's second largest agglomeration.
Mbacké, also known as Mbacké-Baol, was founded in the sparsely populated wilderness of Eastern Baol in 1796 by Mame Maram Muhammad al-Khayri (d. 1802), great-grandfather of Cheikh Ahmadou Bamba Mbacké. Mame Maram was a reputed Muslim jurisconsult. He received the land grant to establish Mbacké from the king of Baol, Amari Ngoné Ndella Fall, who was also king of neighboring Cayor.
