Abstract: Jules Grévy, Édouard Herriot, Jacques Chaban-Delmas, and Bernard Accoyer all presided over the Chamber or the National Assembly at a time when new constitutional rules were coming into effect, between 1875 and 2008. If Chaban-Delmas and Accoyer put the logic of the 5th Republic into practice, Grévy and Herriot had to accompany the establishment of a regime they had fought against. The presidency enabled them to modify the logic of the new rules of political and institutional life.
