<P> In the language of other peoples, Constantinople was referred to just as reverently . The medieval Vikings, who had contacts with the empire through their expansion in eastern Europe (Varangians) used the Old Norse name Miklagarðr (from mikill' big' and garðr' city'), and later Miklagard and Miklagarth . In Arabic, the city was sometimes called Rūmiyyat al - kubra (Great City of the Romans) and in Persian as Takht - e Rum (Throne of the Romans). </P> <P> In East and South Slavic languages, including in medieval Russia, Constantinople has been referred to as Tsargrad (Царьград) or Carigrad,' City of the Caesar (Emperor)', from the Slavonic words tsar (' Caesar' or' King') and grad (' city'). This was presumably a calque on a Greek phrase such as Βασιλέως Πόλις (Vasileos Polis),' the city of the emperor (king)' . </P> <P> The modern Turkish name for the city, İstanbul, derives from the Greek phrase eis tin polin (εἰς τὴν πόλιν), meaning "into the city" or "to the city". This name was used in Turkish alongside Kostantiniyye, the more formal adaptation of the original Constantinople, during the period of Ottoman rule, while western languages mostly continued to refer to the city as Constantinople until the early 20th century . In 1928, the Turkish alphabet was changed from Arabic script to Latin script . After that, as part of the 1920s Turkification movement, Turkey started to urge other countries to use Turkish names for Turkish cities, instead of other transliterations to Latin script that had been used in the Ottoman times . In time the city came to be known as Istanbul and its variations in most world languages . </P> <P> The name "Constantinople" is still used by members of the Eastern Orthodox Church in the title of one of their most important leaders, the Orthodox patriarch based in the city, referred to as "His Most Divine All - Holiness the Archbishop of Constantinople New Rome and Ecumenical Patriarch ." In Greece today, the city is still called Konstantinoúpolis / Konstantinoúpoli (Κωνσταντινούπολις / Κωνσταντινούπολη) or simply just "the City" (Η Πόλη / Η Πόλις). </P>
