Many causes contributed to the unusually long pause between _Emperor and Galilean_ and _Pillars of Society_. The summer of 1874 was occupied with a visit to Norway—the first he had paid since the Hegira of ten years earlier. A good deal of time was devoted to the revision of some of his earlier works, which were republished in Copenhagen; while the increasing vogue of his plays on the stage involved a considerable amount of business correspondence. _The Vikings_ and _The Pretenders_ were acted in these years, not only throughout Scandinavia, but at many of the leading theatres of Germany; and in 1876, after much discussion and negotiation, _Peer Gynt_ was for the first time placed on the stage, in Christiania. The first mention of _Pillars of Society_ occurs in a letter from Ibsen to his publisher, Hegel, of October 23, 1875, in which he mentions that the first act, “always to me the most difficult part of a play,” is ready, and states that it will be “a drama in five acts.” Unless this be a mere slip of the pen, it is curious as showing that, even when the first act was finished, Ibsen did not foresee in detail the remainder of the action. In the course of further development an act dropped out of his scheme. On November 25, 1875, he reports to Hegel: “The first act of my new drama is ready—the fair copy written; I am now working at Act Second”; but it was not until the summer of 1877 that the completed manuscript was sent to Copenhagen. The book was published in the early autumn. The theatrical success of _Pillars of Society_ was immediate and striking. First performed in Copenhagen, November 18, 1877, it soon found its way to all the leading stages of Scandinavia. In Berlin, in the early spring of 1878, it was produced at five different theatres within a single fortnight; and it has ever since maintained its hold on the German stage. Before the end of the century, it had been acted more than 1200 times in Germany and Austria. An adaptation of the play, by the present writer, was produced at the old Gaiety Theatre, London, for a single performance, on the afternoon of December 15, 1880—this being the first time that Ibsen’s name had appeared on an English playbill. Again, in 1889, a single performance of it was given at the Opera Comique Theatre; and yet again in May 1901 the Stage Society gave two performances of it at the Strand Theatre. In the United States it has been acted frequently in German, but very rarely in English. The first performance took place in New York in 1891. The play did not reach the French stage until 1896, when it was performed by M. Lugné-Poë's organisation, L'Œuvre. In other countries one hears of a single performance of it, here and there; but, except in Scandinavia and Germany, it has nowhere taken a permanent hold upon the theatre.
