Georges DIGUIMBAYE, Minister of François Tombalbaye, who later became Ngarta Tombalbaye (you will understand this as you read on), the first President of the Republic of Chad, a country in Central Africa today, but a former colony of French Equatorial Africa (AEF). Born in Fort-Lamy, the capital of Chad, in the 1930s to a father who was a military nurse and a mother who was a housewife, he was the ninth child in a family of eight brothers, all of whom died, and was destined to die like his deceased brothers, but the gods decided otherwise. He will miraculously survive following rituals and sacrifices of all kinds. His life will be closely linked to the history of his country. In this work, the author positions himself as a witness to a certain number of events that have marked the life of the country and his analysis of the situation allows us to understand the various aspects that contribute to a certain knowledge of Chad and even of Africa.
