The floodgates of a literature rich in stimulating ideas were opened and the new subject-matter demanded a new manner, a new style. The influence of Darwin was not lost upon the young generation. The significance of circumstance and environment in the making of man led to a minute painting of the milieu, of the external setting of each individual life at every moment of its existence in drama or fiction. The language of the characters became the language of their class in ordinary life. The action was immediately and directly transferred to the written page and became a record of unadorned reality. The cry for truth became one of the party cries of the period. Naturalistic fiction and naturalistic drama came into being. Within the brief space of less than twenty-five years were born three men whose literary personalities represent this development of German drama. Ernst von Wildenbruch in the main held fast to the traditions of the past, which he treated in historical plays in the manner of a poet who had matured in the period of Germany's unification and was inspired with the consciousness of national renascence. Hermann Sudermann, who rose on the horizon just as the old traditions began to weaken, chose to ignore the past, took his cue from the social note of the present, but sought a compromise with the old forms and with the taste of the great mass of the people. Gerhart Hauptmann, the youngest of the three, discarded all precedent and built upon new foundations with new material in a new manner. By the success which he gained in spite of his uncompromising attitude, he became the leader of the young generation. The intellectual atmosphere in the decade that witnessed the advent of Sudermann and Hauptmann was extraordinarily alive and stimulating and the drama was chosen by an amazing number of young aspirants to literary fame as the vehicle of the message they had for the world. The plays of the period suggest the fermentation going on in the young brains, the unsettling of old and the dawn of new creeds, religious, social and esthetic. The clash of two generations became one of the most popular themes. Caesar Flaischlen, a Suabian, handled it most thoughtfully and effectively in _Martin Lehnhardt_. Though the author modestly called it "dramatic scenes," it was a play presenting with spirited rhythm a phase of the spiritual revolution and moral revaluation then taking place, and in the orthodox uncle and the radical nephew he created two figures full of real dramatic life. The well-to-do and well-satisfied middle-class with its somewhat shopworn ideals was a popular topic with these young men who lustily set about to demolish the Mosaic and other codes of life. Otto Erich Hartleben was hailed as the Juvenal of the society of his time, flaying it mercilessly in satirical comedies like _Education for Marriage_, _The Moral Requirement_, and _Rose-Monday_.
