Julius Mosen (8 July 1803 – 10 October 1867) was a German poet and author of Jewish descent, associated with the Young Germany movement, and now remembered principally for his patriotic poem the Andreas-Hofer-Lied.
Julius Mosen (Julius Moses) was born at Marieney in the Saxon Vogtland, the son of Johannes Gottlob Moses, the cantor and schoolmaster of Marieney. He studied at the Gymnasium in Plauen from 1817 to 1822, and afterwards studied law at the University of Jena. During a two-year-long visit to Italy, he received the inspiration that resulted several years later in his major works (Ritter Wahn, Cola Rienzi, Der Kongreß von Verona).
On his return, he finished his law studies at Leipzig, where he then worked as a lawyer. From 1835 to 1844 he was an independent advocate in Dresden. He had meanwhile shown great literary promise in his Lied vom Ritter Wahn (1831). This was followed by the more philosophical Ahasvar (1838), and by a volume of poems, Gedichte (1836, 2nd ed., 1843), among which Andreas Hofer and Die letzten Zehn vom vierten Regiment became popular. As an active freemason in Dresden he encountered several important literary figures, including Ludwig Tieck, Ludwig Uhland, Georg Herwegh, Richard Wagner and Gottfried Semper, and was soon himself reckoned to be among the best-known German poets.
He also wrote the historical plays Heinrich der Fünfte (Leipzig, 1836), Cola Rienzi, Die Bräute von Florenz, Wendelin und Helene and Kaiser Otto III (the four last being published in his Theater 1842). His tragedies were very well received and were performed at the Dresden court theatre (Dresdner Hofbühne). For his services to German theatre the faculty of Philosophy at the University of Jena awarded him an honorary doctorate.
