In 1983, Lugan authored another thesis for a state doctorate, Between the servitudes of the hoe and the spells of the cow: the rural world in ancient Rwanda. In 1988, he received the M. et Mme Louis Marin prize from the Académie Française for his book The French People Who Made South Africa. In September 1993, he founded the review L'Afrique Réelle, which has been described as a supporter of "Boers-Afrikaners" in South Africa. Lugan has also been involved with far-right news outlets like Minute, National-Hebdo [fr] or Présent, which regard him as a specialist of African history. Until 2006, he hosted a talk show on Radio Courtoisie named the Libre Journal.
Although he does not deny the existence or downplays the figures of the genocide, Lugan controversially claims that the events were not "programmed" by the Hutu leadership, and that president Juvénal Habyarimana was not assassinated by Hutu extremists. In the 1990–2000s, several media and personalities have been condemned for libel for calling Lugan a "genocide denier" or a "supporter of apartheid". At the 2001 World Conference against Racism, Senegalese President Abdoulaye Wade publicly labelled Lugan's work a form of "intellectual racism" and accused him of minimizing the contributions of Black people to the history of Africa in his research.
Lugan's notable work includes several books on Southern Africa, Morocco and Rwanda including "History of South Africa", When Africa was German and African Legacy, Solutions for a Community in Crisis where he describes how individualism hasn't replaced preexisting loyalties to clans, groups, and tribes.
In this book, he rejects what he calls "the victimization paradigm," which says colonial exploitation and the slavetrade brought Africa to its knees, rejects solutions based on Western guilt and claim that a correct interpretation of history is necessary for Africans to "build a future on a more solid foundation" and save an African continent ravaged by famine, economic disaster and civil war. He notably proposes a redrawing of national African frontiers in accordance with ethnic groupings and promotes a new type of democracy, more rooted in those native groupings rather than on Western "one man one vote" system.
