Georg Büchner wrote his works in the period between Romanticism and Realism in the so-called Vormärz era in German history and literature. The goal of the politically liberal poets of this period was that literature of a sham existence would again become an effective organ for renewing political and social life. They were opposed to the Romantics and against the restoration of the old order from prior to the Napoleonic Wars. They fought against convention, feudalism and absolutism, campaigned for freedom of speech, the emancipation of the individual, including women and Jews, and for a democratic constitution. They created a trend-poetry and time-poetry – in other words, poetry that dealt with problems of the time and with a commitment to liberal political ideas. Other writers of this trend and period were Heinrich Heine (author of "Deutschland. Ein Wintermärchen" and "Atta Troll. Ein Sommernachtstraum"), Johann Wolfgang von Goethe (author of "Faust" and "Erlkönig") and Franz Grillparzer (author of "Weh dem, der lügt").
