An important step in his career was his assignment as the director of the Imperial Museum (Müze-i Hümayun) in 1881. He used his position as museum director to develop the museum and rewrite the antiquities laws and to create nationally sponsored archaeological expeditions. Osman Hamdi focused on building relationships with international institutions, notably the University of Pennsylvania, from which he received an honorary degree in 1894. In 1902, he painted the excavation of Nippur as a gift to the University of Pennsylvania Museum. In 1882, he instituted and became director of the Academy of Fine Arts, which provided Ottomans with training in aesthetics and artistic techniques without leaving the empire. In 1884, he oversaw the promulgation of a Regulation prohibiting historical artifacts from being smuggled abroad "(Asar-ı Atîka Nizamnamesi)", a giant step in constituting a legal framework of preservation of the antiquities. Representatives or middlemen of 19th-century European Powers routinely smuggled artifacts with historical value from within the boundaries of the Ottoman Empire (which then comprised the geographies of ancient Greek and Mesopotamian civilizations, among others), often resorting to shadily obtained licenses or bribes, to enrich museums in European capitals.
