Christian Habicht is among the leading historians of the Hellenistic period. He is an authority on Greek epigraphy and on the history of Athens in the centuries between the fall of the Athenian Empire and the establishment of the Roman Empire. He is the author of books on Hellenistic ruler-cults, on the Maccabees, on Cicero, and on Pausanias, as well as the editor of hundreds of previously unpublished inscriptions from the most important places in Greece and Asia Minor. His more than two hundred articles cover topics from the fifth century B.C. to the fourth century A.D. To a new bilingual edition of Polybius, he contributed the introduction and explanatory notes; the six volumes were published in 2010–12. An updated English edition of his doctoral dissertation, submitted in German in 1951, was published as Divine Honors for Mortal Men in Greek Cities: The Early Cases by Michigan Classical Press in 2017.
