Sultan Selim was accusing the Yeniceri Corps after the defeat against Russia. He followed closely the improvements in the European Armies, and he observed the Prussian Army’s educational system. He was aware of the fact that the Ottoman Army needed an immediate reform. He collected new soldiers for the Yeniceri Corps. Thus, he established a modern army called Nizam-i Cedid (24.02.1793).

He established a new treasury called Irad-i Cedid to cover the expenses of this new army. He commissioned European soldiers for the training of the modern Ottoman Army. He constructed Selimiye Barracks and restored Land and Sea Gunnery Schools. After the Yas Agreement, he focused on improvement movements. He sent permanent ambassadors to Paris, London, Vienna, and Berlin and opened embassies in these cities. French was approved as the legal foreign language of the empire. Foreign language and science education gained importance. Some technical works were translated into Turkish.
