World War I dealt a heavy blow to classical studies, as to all humane letters, and the numbers of those studying Greek and Latin were noticeably affected; but scholars showed courage and energy in adapting themselves to new conditions. Wilamowitz-Moellendorff continued to be active, and his last decade saw more abundant and more important publications than any other of his career. His pupils produced much important detailed work: Felix Jacoby (1876–1959) began and carried far a learned edition of the fragments of the Greek historians; Paul Maas (1880–1964) showed rare expertise in Greek metrics, textual criticism, and paleography; Eduard Fraenkel (1888–1970) did valuable work on Plautus’ relation to his Greek originals and later devoted to Aeschylus’ Agamemnon one of the most learned of all commentaries; and Rudolf Pfeiffer (1889–1979) wrote a masterly commentary on Callimachus and an important history of classical scholarship.

Reacting against the classicism of the age of Goethe, scholars of the late 19th century saw the study of antiquity mainly from a historical standpoint: they accumulated masses of detail, which sometimes led to dryness, and tended to think exclusively in terms of concrete fact. Discontent arose with the recognition that an excessive preoccupation with the details of their development can harm the understanding of works of literature and thought. Attempts were made to revive classical scholarship by rescuing it from the domination of historical study. Werner Jaeger (1888–1961), an Aristotelian scholar who succeeded Wilamowitz-Moellendorff in his Berlin chair, attempted, without much success, to achieve this by institutional means. More was accomplished by Karl Reinhardt (1886–1958), who, though a devoted pupil of Wilamowitz-Moellendorff, had been in contact from his youth with the ideas of Nietzsche and of the circle around the poet Stefan George. Combining deep learning with refined sensibility, Reinhardt did important work on pre-Socratic philosophy and on Poseidonius and later on Sophocles, Aeschylus, and Homer.

Even before the start of World War II, National Socialist persecution had gravely damaged scholarship in Germany, the main centre of classical studies. The United States and, to an even greater extent, England benefited from the efflux of scholars from the Continent. Jaeger and two other eminent pupils of Wilamowitz-Moellendorff, Paul Friedländer (1882–1968) and Hermann Fränkel (1888–1977), spent the rest of their lives in the United States. So did the Russian M.I. Rostovtzev (1870–1952), who made a vast contribution to the study of the social and economic history of the ancient world. Thaddeus Zielinski (1859–1944), the Polish scholar who did important work on Ciceronian clausulae (clauses) and other topics, was murdered by the Nazis. Eduard Norden (1868–1941), who studied the formal prose of the ancients and did important work on ancient religion and on Latin literature, died in Switzerland. Jacoby, Maas, Fraenkel, and Pfeiffer, as well as the eminent archaeologist Paul Jacobsthal (1880–1957), settled in England, where Fraenkel in particular taught most effectively, creating links between English and continental scholarship. Pfeiffer, like Kurt von Fritz (1900–85), who spent the war years in America, returned to Germany.

In Italy the school founded by Vitelli continued under the leadership of Giorgio Pasquali (1887–1952), a pupil of Schwartz and Leo, and Gaetano de Sanctis (1870–1957) did important work on ancient history. In Sweden Einar Löfstedt (1880–1955) and his school threw much light on Vulgar Latin and indirectly on Latin in general, and M.P. Nilsson (1874–1967) wrote a learned history of Greek religion.

In France classical studies to some degree slumbered under the conservative establishment, but Antoine Meillet (1866–1936) and others advanced the study of linguistics, and Louis Gernet (1882–1962) founded an important school of scholars who applied the techniques of modern sociology and anthropology to the study of antiquity.

In England A.E. Housman (1859–1936) continued with great distinction the tradition of exclusively textual study, editing Juvenal, Lucan, and most notably Manilius. J.D. Denniston (1887–1949) made a valuable study of the Greek particles. Edgar Lobel (1887–1981) from 1927 edited the literary papyri from Oxyrhynchus with unrivaled expertise. Sir Denys Page (1908–78) edited many Greek poetical texts with great success. Gilbert Murray (1866–1957) was not only a literary scholar but, like Jane Harrison (1850–1928), a pioneer in the use of anthropological and sociological methods in the study of antiquity. F.M. Cornford (1874–1943) shared this interest but went on to contribute significantly to the study of Plato and the pre-Socratics. E.R. Dodds, starting with Neoplatonism, applied psychological as well as anthropological knowledge to the study of early Greek thought, also writing excellent commentaries on Euripides’ Bacchae and Plato’s Gorgias. Sir John Beazley (1885–1970), with deep learning and refined sensibility, put the whole study of Greek vase painting on a new basis by applying the method of the 19th-century Italian art critic Giovanni Morelli to the identification of individual painters.

The way in which research may (and indeed must) transcend the conventional limits of individual disciplines is exemplified during this period in the history of the Homeric Question: the efforts of scholars in such diverse fields as linguistics, archaeology, Hittite studies, folklore, and comparative oral literature have materially advanced understanding of the poems. The problem was transformed by the proof of an American scholar, Milman Parry (1902–35), that the poems show many characteristics of a poetic tradition that has passed through a long phase of oral transmission.

Excavation continued, despite many political and financial difficulties, and a steady stream of discoveries came from Greece, Italy, and other Mediterranean lands. Perhaps the most exciting new find after World War II was the discovery by the Greek archaeologist Spyridon Marinatos of a Minoan town, with fine and well-preserved frescoes, on the island of Thera. Although large-scale excavations in search of papyri have been discontinued for many years, new papyri have not ceased to be discovered. Since World War II the authors who have benefited most have been Callimachus, Menander, and Stesichorus. In 1952 Michael Ventris showed that the language of the so-called Linear B syllabic script on clay tablets found at Mycenae and other places is Greek, thus throwing light on a far earlier stage of the language than had previously been known.

The history of classical scholarship has continued to be one of activity and progress. The publication of new inscriptions and of new papyri and other manuscripts has yielded important new material, and, considering the limited resources available, the task of presenting the texts of literary works and documents in up-to-date editions has been carried out with considerable success. Lately the Hellenistic and Imperial periods have received greater emphasis and have been given greater credit for their achievements.

But such are the threats presented by social change and utilitarian pressures that heroic efforts will be needed if progress is to continue. In Europe at the beginning of the 20th century many schools gave a good grounding in the ancient languages. By late in the 20th century that was no longer the case, and, as a result, the years when the memory is at its best for learning new languages are wasted. In the United States, vast reserves not only of money but also of talent and enthusiasm have made a large contribution to classical studies, but progress has been impeded not only by the failure of the schools to teach the ancient languages but also by the materialism and utilitarianism that increasingly held sway both there and in Europe.
