They speak the Dan language, a Southeast Mande language. The Dan are known for their art, especially their mask rituals (Ge or Gle), as well as their secret society, Gor. Gor (Dan for "leopard") is a peacemaking society, not to be confused with the brutal Ekpe (leopard) society of Nigeria. The Dan originally came from the western Sudan region to the north, part of present-day Mali and Guinea. The location and movements of the Dan, Mano and We can be reconstructed from as early as the 8th century , at which time the Dan and Mano were located in the savanna region of the northern Ivory Coast. In the tenth century, political turmoil, population growth and land depletion caused the Dan to migrate south of the Nimba range and into the high forests.
