Palacký, though entirely national and Protestant in his sympathies, was careful to avoid an uncritical approbation of the Reformers' methods, but his statements were held by the authorities to be dangerous to the Catholic faith. He was compelled to cut out parts of his narrative and to accept as integral parts of his work passages interpolated by the censors. After the abolition of the police-censorship in 1848 he published a new edition, completed in 1876, restoring the original form of the work. The fairest and most considerable of Palacký's antagonists in the controversy aroused by his narrative of the early reformation in Bohemia was Baron Helfert, who received a brief from Vienna to write his "Huss und Hieronymus" (1853) to counteract the impression made by Palacký's "History". Konstantin von Höfler, a German professor of history at Prague, edited the historical authorities for the period in a similar sense in his "Geschichte der hussitischen Bewegung" in Bohmen. Palacký replied in his "Geschichte des Hussitenthumes und Professor Löffler" (Prague, 1868) and "Zur böhmischen Geschichtschreibung" (Prague, 1871).
