What is "mdewakanton"

Mdewakantonwan (currently pronounced Bdewákhathuŋwaŋ, also M'DAY-wah-kahn-tahn) are one of the sub-tribes of the Isanti (Santee) Dakota ( Sioux). Their historic home is Mille Lacs Lake in central Minnesota, which in the Dakota language was called Mde wakan (mystic/spiritual lake). Together with the Wahpekute (Waȟpékhute - “Shooters Among the Trees”), they form the so-called Upper Council of the Dakota or Santee Sioux (Isáŋyáthi - “Knife Makers”).
