Why is Istanbul called Istanbul? – BC. In 700, Istanbul, the important settlement area of Ancient Greece, was called Byzantium. This is a name given by the Greek Dorians. Later, the names Konstantinniye, Konstantinopolis, Nova Roma, Islambol were also used.
In many ancient inscriptions, even Evliya Çelebi’s voyage, the name “Islambol” was used extensively. In Constantinople, “is” means the city in ancient Greek, while “tin” and “polin” means the city. Over time, the transition to Turkish became “Istanbul”. In fact, this name used from the very old times only when passing to Turkish “Islambol” as “Istanbul” was passed.
