Outside Germany, Heeren's volume earned immediate acclaim. It was soon translated into several foreign languages. The effect of this reception on Heeren was lasting, no doubt explaining why, in his unpublished autobiographical writings, he would continue to lay particular stress on the importance of what he called the “politico-mercantile” dimension of history. As a Göttingen professor, however, Heeren did not confine himself to that subject. He earned an enviable reputation as a teacher. As a writer, he would be recognized for his broad range of historical interests. Although they would later pass into relative obscurity, his "History of Ancient Civilizations" (Göttingen, 1799) and his "History of European States and their Colonies" (Göttingen 1809) met with the success of his earlier work, going through numerous editions. Though he would show himself to have little real feel for medieval history, he did venture some work in that direction as well. His "History of Classical Literature Since the Revival of Learning" (Göttingen, 1792–1802, 2 vols) was by his contemporaries judged something of a failure. On the other hand, his "Untersuchungen über die Kreuzzüge", translated into French as "Essai sur l'influence des croisades" ("Essay on the Influence of the Crusades") by his friend Charles de Villers, would in 1806 be awarded a prize by the Institute de France.
