The Dagaaba people are an ethnic group located north of the convergence of Ghana, Burkina Faso and Côte d'Ivoire. They speak the Dagaare language, a Gur language made up of the related Northern Dagaare dialects, Southern Dagaare dialects and a number of sub dialects. In northern dialects, both the language and the people are referred to as Dagara. They are related to the Birifor people and the Dagaare Diola. The language is collectively known as Dagaare, and historically some non-natives have taken this as the name of the people. One historian, describing the former usage of "Dagarti" to refer to this community by colonials, writes: "The name 'Dagarti' appears to have been coined by the first Europeans to visit the region, from the vernacular root dagaa. Correctly 'Dagari' is the name of the language, 'Dagaaba' or 'Dagara' that of the people, and 'Dagaw' or 'Dagawie' that of the land."

The Dagombas or Dagbamba are an ethnic group of Ghana, and Togo. They number more than 3.1 million people. The term Dagbamba is originally extended to refer to other related peoples who were unified by Naa Gbewaa including the Mamprusi and Nanumba. The Dagomba country is called Dagbon and they speak Dagbanli language. Dagbanli is the most spoken language of northern Ghana and second most widely spoken local language of Ghana. Dagbanli belongs to the Mabia (Mole-Dagbani) subgroup of the Gur languages, a large group of related languages in West Africa. The Dagomba practises both patrilineal and matrilineal systems of inheritance.
