By this name, it is known the German writer Karl Ludwig Friedrich Joachim von Arnim, born in Berlin in 1781, and died in Wiepersdorf in 1831. Descendant of a family of the nobility of Brandenburg are educated in Berlin with her grandmother. The study found refuge from the tense family atmosphere: was dedicated first of all to history and philosophy and, subsequently, to mathematics and the natural sciences. In 1798 he began studying in Halle physics, chemistry, mathematics and jurisprudence, while he published small trials related to the Sciences of nature. Contact with the literary circles of Göttingen, city which moved in 1800, and his friendship with Clemens Brentano, claimed you in his decision to devote himself to literature.
His literary debut came at the hands of Hollins Liebe leben (living the love of soot, 1801), a novel style of the Werther by Goethe. A journey of training through various European countries, whose climax was the tour that made by the Rhine with Brentano to the city of Düsseldorf, became mature the plan from the collection Des Knaben Wunderhorn (the magic Horn of the boy, 1805), which collected the fruit of the fascination that felt both by forms of popular culture. Their collaboration over the years both resided in Heidelberg (1805-1808) was also born the Zeitung für Einsiedler, newspaper, which became the organ of expression of the romantic circle of Heidelberg. In its first issue appeared the poem Lieben und geliebt zu werden (to love and be loved) that Arnim dedicated to his future wife Bettina, the sister of Brentano.
Arnim always took party in the socio-political chronology of his time and knew how to reflect the contradictions of this period in the novel Armuth, Bauern, Schuld und Busse der Gräfin Dolores (poverty, wealth, guilt and Penance of the Condesa Dolores, 1810). On his return to Berlin in 1811 founded the "Cristiano-Alemana society" ("Christlich-Deutsche-Tischgesellschaft"), a private and conservative circle that gathered the most important men from Berlin and faithful reflection of the transformation that had been slowly taking place in the ideology of the writer. This transformation is reflected in the fragment Die Kronenwächter (keepers of the Crown, 1817), on the basis of medieval motifs is the germ of the German historical novel.
Its literary meaning should be attributed above all to the palpable confrontation in all their narratives between reality and dream (Die Majoratsherren, the Lords of the Majorat, 1811; Isabella von Ägypten, Karls des Funften erste Jugendliebe, Isabel of Egypt, the first love of youth of Carlos V, 1812). His drama Halle und Jerusalem (Halle and Jerusalem, 1811) has not been never put in scene.
