Séguier was an absolutist. He brutally suppressed the revolt of the Va-nu-pieds in 1639 and directed the prosecution of the Marquis de Cinq-Mars and of F.-A. de Thou. Séguier assisted Richelieu in establishing the Aeadémie Française and became an academy member in 1635. A well-educated man, he was a devoted bibliophile and collector of manuscripts. He accumulated a valuable library of 4,000 manuscripts and 10,000 books. Some of the manuscripts and papers that Séguier collected as chancellor are in the M. E. Saltykov-Shchedrin State Public Library in Leningrad.
