The Emirate of Rum is the oldest and most enduring Islamic state in Europe as it has stood in Europe independent as of 759 until the Late XIII century when the city of Rum known by the Latin and Christian armies of the west as Constantinople was taken after a three year continuous siege by the Christian coalition between Cyprus, Athenas and Rome. The city is ephemerally recovered to the Islam in 1358 when the Turks Seljucids manage to take the city their presence. Whatsoever, it's one of the most cruel eras that the city endured finishing by 1372 with the coalition retaking the city.
