[1] A Professor of ancient history and classics at the University of Bordeaux from 1891, Jullian was awarded a chair at the Collège de France in 1905, where he taught national antiquities until 1930.

He was made Grand Officier de la Légion d'Honneur in 1926, and was elected to the Académie française in 1924.

Jullian is the author of a monumental Histoire de la Gaule, published in eight volumes between 1907 and 1928, which has influenced Celtic studies throughout the 20th century.

He attended the lycée of Marseille between 1864 and 1877, then the École Normale Supérieure, where he earned an agrégation in history and geography in 1880.

[5]Jullian was involved with the controversy over the archaeological findings at Glozel in France; he was among those who believed the artefacts recovered were forgeries.
