Have you ever wondered how the city of
    Istanbul got its' name?
    The origin comes from the previous name
    of the city Constantinople, "The city of Constantine" and is a
    direct referral to that city in
    Greek.  The Greeks used to refer to the city of Constantinople as "I
    Poli",
    "The city", or in short "Poli". 
    The name Istanbul originates from the Arabs
    hearing the Greeks say "Eis ten
    Polis", Greek "In the city" and the Arabs using that name for
    the city.  Eventually the Greek saying became the accepted name of the
    city, a direct referral to the original name! It became the official name of
    city by the Turkish government in the early 20th century.
