In French colonial history, some names resonate more loudly than others: Jules Ferry, Albert Sarraut and Lyautey. But one of the most striking figures, although less mentioned today, remains Paul Doumer. Governor General of Indochina from 1897 to 1902, and future President of the French Republic, he was above all a rigorous, pragmatic and authoritarian administrator, whose actions had a profound impact on Vietnam, Laos and above all Cambodia.
