In the fourth century, Rome, , Antioch, and Ephesus were considered the four apostolic sees. However, with the foundation of as a capital, the started to assert their capital as an apostolic see, especially in the of Constantinople in 381 a.d. The relics of St. Andrew were later discovered in order to justify their assertion. From the beginning of the fifth century, the other apostolic sees this innovation.
