Holger Drachmann in the context of "Skagen Painters"

The Modern Breakthrough (Danish: Det moderne gennembrud; Norwegian: Det moderne gjennombrudd; Swedish: Det moderna genombrottet) was a movement of naturalism and debating literature of Scandinavia which replaced romanticism near the end of the 19th century.

The term "The Modern Breakthrough" is used about the period 1870-1890 in the history of literature in Scandinavia, which in this period had a breakthrough from the rest of Europe. Danish theorist Georg Brandes is often considered to be the "wire-puller" behind the movement, although some of the authors had already begun to write in a realistic style before he formulated the aesthetic paradigm of the movement. His lectures at Copenhagen University starting 1871 and his work Main Currents in 19th Century Literature (Danish: Hovedstrømninger i det 19. Aarhundredes Litteratur) mark the beginning of the period.

Danish literature (Danish: Dansk litteratur) stretches back to the Middle Ages. The earliest preserved texts from Denmark are runic inscriptions on memorial stones and other objects, some of which contain short poems in alliterative verse. In the late 12th century Saxo Grammaticus wrote Gesta Danorum. During the 16th century, the Lutheran Reformation came to Denmark. During this era, Christiern Pedersen translated the New Testament into Danish and Thomas Kingo composed hymns. Fine poetry was created in the early 17th century by Anders Arrebo (1587–1637). The challenges faced during Denmark's absolute monarchy in 1660 are chronicled in Jammersminde (Remembered Woes) by Leonora Christina of the Blue Tower. Ludvig Holberg (1684–1754), influenced by the ideas of the Enlightenment and Humanism, is considered the founder of modern Danish and Norwegian literature. Neoclassical poetry, drama, and the essay flourished during the 18th century influenced by French and English trends. German influence is seen in the verse of the leading poets of the late 18th century such as Johannes Ewald and Jens Baggesen. Other 18th century writers include the hymn writer Hans Adolph Brorson and the satirical poet Johan Herman Wessel.

During Denmark's Golden Age (1800–1850), literature centred on Romantic thinking, with authors such as philosopher Henrik Steffens (1773–1845) and the poet Bernhard Severin Ingemann (1789–1862). One of the most important figures in Danish literary culture was Nikolaj Grundtvig (1783–1872). Hans Christian Andersen (1805–1875) is remembered first and foremost for his fairy tales, written between 1835 and 1872. Søren Kierkegaard (1813–1855) was an existentialist philosopher and a theologian. Jens Peter Jacobsen (1847–1885) began the naturalist movement in Denmark with his romantic, melancholic poems. The Modern Breakthrough was a Scandinavian movement influenced by naturalism towards the end of the 19th century (1870–1890), led by Georg Brandes (1842–1927). Other writers include Holger Drachmann (1846–1908), Herman Bang (1857–1912), and Sophus Schandorph (1836–1901).
