Naaba accepted the French protectorate. The Mossi and several other peoples played a significant role in France's military during World War II. They constituted part of the corps in the military troops of French West Africa, known in French as the Tirailleurs Sénégalais. Organization of Mossi society The Mossi people have organised their society in an original hierarchic process in which family and state are the key elements. The Mossi people are very heterogeneous. When horsemen invaded from the south they created a political or ruling class, called Nakomse (sing. Nakoambga), and a spiritual class called Tengabisi. All chiefs come from the ruling class. The Tengabisi include Saya (smiths), Nyonyose (farmers), Yarse (weavers and merchants), and others. The origins of the Nyonyose are diverse: In the north their ancestors were Dogon and Kurumba, in the southwest their ancestors were Lela, Nuna, Sisala and others, and in the far east they were Gurmantche. These people were united into a new ethnicity called Mossi in about 1500. It is a mistake to describe a "Nyonyosé tribe" or the "art of the Nyonyosé" because the Nyonyose do not exist outside Mossi society. All Nyonyosé are Mossi. At the same time, it is a mistake to assume that all segments of Mossi society are culturally identical, for the differences between the Nakomsé and the Tengabisi are striking; only the Tengabisi use masks, and only the Nakomsé use figures in the context of political celebrations. The Nakomse are the political class, and the Tengabisi are the spiritual class. Mogho Naaba and the Nakomse The highest position in Mossi society is that of the Mogho Naaba, who is given executive power. The Mogho Naaba's role is to rule the entire population and to protect the kingdom. Today, he lives in Ouagadougou, the historical capital of the Mossi Empire and present capital of Burkina Faso. Though the political dynamic of the country has changed, the Mogho Naaba is recognised by his people and has substantial authority. Second to the Mogho Naaba come the nobles, Nakomse (“people of power”; sing. Nakoambga), who all are from the family of the Mogho Naaba, whether they be brothers, sisters, cousins, or otherwise. All dignitaries come from the Mogho Naaba's family. The Nakomse are often assigned territories in the kingdom as governorships and rule in the name of the Mogho Naaba. As in the past, the Mogho Naaba needs the support of
