Denis became known as a specialist of Germany and Bohemia, and played a major role in the establishment of the Czechoslovak state in 1918. Along with Louis Léger, he is considered to be one of the most highly regarded 20th-century historians of the Slav world in France. Upon his death, the Czechoslovak state bought his residence in Paris in order to create an institute for Slavic studies.
