Language

Although he ruled Egypt, where the common language was Arabic, Isma'il spoke Turkish best and could not speak Arabic. Nevertheless, under his reign, the use of Arabic in government gradually increased at the expense of Turkish, which had been the language of the ruling elite in the Nile delta during the hundreds of years of Ottoman rule. In the following decades, Arabic would further expand and eventually replace Turkish in the army and in administration, leaving Turkish to be used only in correspondence with the Ottoman Sultan in Constantinople.
