Istanbul was the name used by at least the later half of the 20th century for an Earth city which was known at various points as Constantinople and Byzantium. (AUDIO: Rule of the Eminence)

Byzantium[edit | edit source]

Byzantium was, according to Bernice Summerfield, the oldest name of Istanbul. (PROSE: Shadowmind)

Byzantium remained the name of the city around the time of Jesus Christ. The First Doctor, Barbara, Vicki and Ian visited the city in 64 AD, and found it to be a city struggling with three groups vying for power: the Jewish Pharisees, the Roman Empire and the adherents of the fledgling Christian religion. (PROSE: Byzantium!)

Byzantium begat New Byzantium. The Seventh Doctor once told Ace that he thought New Byzantium stole the name because the two cities had a similar geography, both cities being set "on an isthmus of land, cut through by a strait linking two seas". (PROSE: Shadowmind)

Constantinople[edit | edit source]

The name switched to Constantinople in the early part of the first millennium. Benny once told Ace that the name switch was in honour of Emperor Constantine. She went on to say that Constantinople was "the capital of the Eastern Roman Empire until the 15th century, when it was captured by the Turks". (PROSE: Shadowmind)

In the 3rd century, an incarnation of the Doctor encountered Fenric in Constantinople, where he defeated him at chess and trapped him in a flask.

(TV: The Deadly Assassin)

In the 10th century, the Fifth Doctor and Peri Brown visited Constantinople. (PROSE: Methuselah)

Piloting the Doctor's TARDIS, Nardole visited 12th century Constantinople and ruled for a while as Emperor, as one of "a few accident stop-offs" before successfully retrieving the Twelfth Doctor from Harmony Shoal's head office in 21st century New York. (TV: The Return of Doctor Mysterio)

In 1914, the Seventh Doctor and Ace visited Constantinople to locate and dispose of a malfunctioning Krivani interstellar drive. (PROSE: Ante Bellum)

In 1924, River Song met Bertie Potts while their boat, headed to an archaeological dig in Mesopotamia, was docked in the city. (AUDIO: The Boundless Sea)

At some point, Constantinople had a cash and carry that the Fourth Doctor believed to be "far superior" to P. Fords in New York City. (COMIC: Time Lady of Means) Prior to his visit to Quinnis, the First Doctor acquired Turkish delights from Constantinople. (AUDIO: Quinnis)

Istanbul[edit | edit source]

By 1963, Constantinople had become Istanbul. Susan Foreman, while taking school on Earth, once forgot the time and called the city Constantinople. In consequence, her geography teacher made his entire 4G class chant, "It's Istanbul, not Constantinople!" (PROSE: Time and Relative)

In the 21st century, the Ninth Doctor fought Sontarans on a rooftop in Istanbul. Sally Sparrow saved his life from one of them, and gave him her Christmas homework for instructions for when the TARDIS would "burp" and jump forward in time twenty years without the Doctor. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow)

Byzantium again[edit | edit source]

The city was again known as Byzantium by the time of the Earth Alliance's war with the Eminence. The Alliance's media centre was located there. (AUDIO: Rule of the Eminence)

Behind the scenes[edit | edit source]

Narratives in the Doctor Who universe have not, as of 2019, particularly defined when the city's name changed.

According to the pseudo-narrative Torchwood website, 4th century BC Istanbul had sewers full of Weevils.
