The vast majority simply call it Istanbul, with the Balkan countries and Russia sometimes also referring to it as Tsarigrad and Romania, Moldova and Georgia still sometimes using the old name of Constantinople.
However, Greece is the lone holdout which refuses to recognise the last 500 years of history and stubbornly refuses to call it anything other than Constantinople (I guess they didn’t like it better that way).
Here’s more on the name change of the city:
Byzantium: The Ancient Name
- Origins: Byzantium was originally a Greek colony founded around 657 BCE by settlers from the city-state of Megara. The city was named after their leader, Byzas.
- Location: It was strategically located on the Bosporus Strait, a key point for controlling trade between Europe and Asia.
Constantinople: The New Rome
- Name Change: In 330 CE, the Roman Emperor Constantine the Great declared Byzantium as the new capital of the Roman Empire, renaming it Constantinople, meaning “City of Constantine” (Κωνσταντινούπολις in Greek).
- Significance: It became the center of the Eastern Roman Empire, later known as the Byzantine Empire, and remained a key cultural and political hub for over a millennium.
- Language: In Greek, it was often referred to as “The City” (ἡ Πόλις), emphasizing its significance as the empire’s heart.
Istanbul: The Modern Identity
- Ottoman Conquest: The city was conquered by the Ottoman Turks under Mehmed II in 1453 and became the capital of the Ottoman Empire.
- Evolution of the Name:
- The name Istanbul derives from the Greek phrase εἰς τὴν πόλιν (pronounced “is tin polin”), meaning “to the city.” This reflects how locals referred to the city colloquially.
- The name Istanbul was used informally by the Ottoman population for centuries, though Constantinople remained the official name in many international contexts.
- In 1930, the Turkish Republic under Mustafa Kemal Atatürk formally adopted Istanbul as the city’s official name as part of a broader effort to standardize Turkish place names.
Tsarigrad: The Slavic Connection
- Meaning: The term Tsarigrad (Цариград or Tsargrad) translates to “City of the Tsar” or “City of the Emperor” in Slavic languages, reflecting the Byzantine Empire’s significance as the seat of the emperor.
- Usage:
- This name was commonly used by Slavic peoples (e.g., Bulgarians, Serbs, and Russians) during the medieval period.
- It underscores the cultural and religious influence of the Byzantine Empire on Eastern Europe, especially among Orthodox Christian nations.
- Modern Usage: Though archaic, Tsarigrad can still be encountered in historical or poetic contexts, particularly in Bulgarian and Serbian literature.
Name Changes Across Europe
- The city’s name changed in different languages and contexts over time, reflecting cultural and political shifts:
- Western Europe: The name Constantinople was dominant until modern times.
- Eastern Europe: Slavic peoples often referred to the city as Tsarigrad during the Byzantine and early Ottoman periods.
- Arabic and Persian: The city was known as Qustuntuniya.
- 1930 Transition: Many European countries began using “Istanbul” officially after Turkey’s formal adoption of the name. However, some older maps and documents continued to use Constantinople for decades.
Cultural and Historical Legacy
The name changes from Byzantium to Constantinople to Istanbul, as well as the use of Tsarigrad, highlight the city’s enduring role as a cultural, religious, and political crossroads.
Each name reflects a different layer of its history:
- Byzantium: Ancient Greek heritage.
- Constantinople: The Christian and Byzantine era.
- Istanbul: Ottoman and modern Turkish identity.
- Tsarigrad: The city’s status as a beacon of empire for the Slavic world.

Anders Danielsson says
In Sweden we still know Istanbul’s name in Old Norse, which is Miklagård and simply means “the big town”.
Scandinavian mercenaries served in the imperial Varangian guard (Väringarna) around 1000 CE and were quite impressed by Constaninople’s size – Birka and Lund were the largest towns in their home countries with only a couple of thousand inhabitants each and neither Stockholm nor Copenhagen (Köbenhavn) were even founded then.
