Die Grenzboten was a German language, national liberal magazine published from 1841 to 1922, sometimes weekly and sometimes fortnightly.
They made the magazine, not least through many of their own contributions, the most influential mouthpiece of the national-liberal bourgeoisie up to the founding of the German Reich in 1871.
From that point, the orientation of the magazine changed from a purely liberal to a more conservative one.
Its subtitle was initially Blätter für Deutschland und Belgien ("Papers for Germany and Belgium").
The journal was important because, through it, Schmidt and Freytag developed the theory of literary realism.
