The next appearance was that of Willem Kloos (1857–1938), who had been the editor and intimate friend of Perk, and who now led the new movement. His violent attacks on recognized authority in aesthetics created a considerable scandal. For some time the new poets and critics found a great difficulty in being heard, but in 1884 they founded a review, "De Nieuwe Gids" ("The New Guide"), which was able to offer a direct challenge to the old guard's periodicals. The new movement was called "Tachtigers" or "Movement of (Eighteen-)Eighty", after the decade in which it arose. The "Tachtigers" insisted that style must match content, and that intimate and visceral emotions can only be expressed using an intimate and visceral writing style. Prime influences of the "Tachtigers" were U.K. poets such as Shelley and the French naturalists.
