Droysen was born at
Treptow in
Pomerania (now Trzebiatów in
Poland) on 6 July 1808. His father,
Johann Christoph Droysen, was an army chaplain who had been present at the celebrated siege of
Kolberg in 1806–1807. As a child, Droysen witnessed some of the military operations during the
War of Liberation, his father by then being pastor at
Greifenhagen, in the immediate neighbourhood of
Stettin, which was held by the
French for most of 1813. These youthful impressions laid the foundation of his ardent attachment to the
Kingdom of Prussia. He was educated at the
gymnasium of Stettin and at the
University of Berlin; from 1827 to 1829 he was the private tutor of
Felix Mendelssohn, who set several of his poems in his Op. 9
12 Songs. In 1829 he became a master at the
Graues Kloster, one of the oldest schools in Berlin; in addition, he gave lectures at the University of Berlin, from 1833 as
Privatdozent, and from 1835 as professor, without a salary. The famed historian
Jacob Burckhardt visited his class in his last semester (1839–40). During these years Droysen studied classical antiquity; he published a translation of
Aeschylus in 1832 and a paraphrase of
Aristophanes (1835–1838), but the work by which he made himself known as a historian was his
Geschichte Alexanders des Grossen (
History of Alexander the Great; Berlin, 1833 and other editions), a book that long remained the best work on
Alexander the Great. It was in some ways the herald of a new school of German historical thought, for it idealized power and success, a conceptual framework Droysen had learned from the teaching of
Hegel. Droysen followed the biography of Alexander with other works dealing with Alexander's
Greek successors, published under the title of
Geschichte des Hellenismus (
Hamburg, 1836–1843), in which he created the term "
Hellenistic" to refer to the period between Alexander's conquests and the emergence of the
Roman Empire. A new and revised edition of the whole work was published in 1885, and translated into French, but not at the time into English. appeared in 1846 and his
Outlines of the Principles of History, published 1858, translated 1893, was widely read throughout German universities. He followed this with
Erhebung der Geschichte zum Rang einer Wissenschaft (1863), a methodological study that reflected his new approach to research and writing. ==History meets politics==
