Hamdanid dynasty
Among Canard's major scholarly achievements are his history of the Hamdanid dynasty, as well as his studies on the Fatimid Caliphate, a field that at the time was otherwise the almost exclusive reserve of Vladimir Alexeyevich Ivanov (1886–1970). He also made important contributions on the history of Muslim relations with the Byzantine Empire, and along with the Belgian Henri Grégoire (1881–1964) supervised the French edition of Alexander Vasiliev's (1867–1953) monumental "Byzantium and the Arabs" (Византия и арабы).
