constantinople was built in 330 how long did it last until captured by the ottomans
From the mid-5th century to the early 13th century, Constantinople was the largest and wealthiest city in Europe and it was instrumental in the advancement of Christianity during Roman and Byzantine times as the home of the Ecumenical Patriarch of Constantinople and as the guardian of Christendom's holiest relics such as the Crown of Thorns and the True Cross. After the final loss of its provinces in the early 15th century, the Byzantine Empire was reduced to just Constantinople and its environs, along with Morea in Greece, and the city eventually fell to the Ottomans after a month-long siege in 1453.
