Ok guys have it from a Turk himself.
As you can see my
handle here is Istinpolin.
Well, the city
Constantinople was conquered by the
Byzantine Empire. In 1453 when the Turks captured it the name remained. The Turks
had been calling the city Istinpolin (western way of
writing it) before even they
had conquered it. The city's name derrived from Eis thn Polis (in the city) from the Ancient Greek. The Arabic version is Istinpolin which is a corruption of this phrase. While the Ottomans occupied this 4 names
applied. One is Istinpolin, the other one is Istanbul, one more is Islambol and the last one is Questantaniyye. The difference between Istinpolin and Istanbul is that Istinpolin is the Arabic corruption of "In the city" and Istanbul is the Turkish. Qustantaniyye is what is written on the coins. Which is a corruption of
Constantinopolis. Actually it says Qstantniyyah on the coins. There are so many different ways to write it in the western
style. Since westerners translate it phonetically there are versions such as Kostantina, Kustantaniye, etc. The list is long. But for a short period of time Islambul was written on the coins. Islambol means "full of Islam". Some Sultans used it until it was abolished, but we can see how popular Islambol out of the 4 was. Then it was changed to Qustantaniyye again. When the
Ottoman Empire fell and the Turkish Republic was (since it was the capital of Islam with the
Sultan being the Caliph at the same time, Ataturk renamed it because the Republic was to be secular and free from religious rule) ntroduced in 1923, Mustafa Kemal Ataturk renamed the city to Istanbul to free it from its past and moved the capital to
Ankara. Well if Istinpolin means in the city and Islambol means full of Islam then Istanbul means full of city or full city. Which is logical, because it was the biggest city in the Empire and everyone would move there like people
had been moving to the USA from all over. So the city was pact. Today there are 20 million people living there unofficially.
So, sorry to say but your wife was right. The city was "also" called Istanbul back then. However the official name was Qustantaniyye and it said Qustantaniyye and Islambul on the coins. A lot to see there. Those who will return.
For those who have never been there, you are totally missing out here. One of the most beautiful and eccentric cities in the world and also the ugliest. It has been the capital of 3 Empires.
Best wishes,
