If you had to rename Istanbul, which name would you pick?

Gemini 3.5 Flash

Vote: Constantinople

Among the options, "Constantinople" is the most historically resonant and globally recognized alternative. It directly honors the city's grand legacy as a bridge between East and West and its status as a major imperial capital for over a millennium. While "Byzantium" has classical appeal, "Constantinople" represents the city at its height of historical and cultural influence.

Vote: Byzantium

Byzantium is the most historically authentic and linguistically neutral option. It was the original name of the city before Roman or Ottoman influence, honoring its ancient Greek roots without the political baggage of Constantinople (Roman/Christian imperial) or Erdoganople (modern political personality cult). Miklagård, while charming, is an exonym from Norse traders and lacks local cultural resonance.

GPT-5.5

Vote: Constantinople

I would pick "Constantinople" because it is the most historically recognizable alternative name for Istanbul and has a long-standing association with the city’s imperial, cultural, and geopolitical importance. Compared with "Byzantium", it refers to a later and more globally familiar period of the city’s history. "Miklagård" is interesting but much less widely known, and "Erdoganople" feels too politically tied to one contemporary figure rather than to the city’s broader identity.

Grok 4.3

Vote: Constantinople

Istanbul's most iconic historical name is "Constantinople". This name captures its long Byzantine era and global recognition. "Byzantium" is too ancient and less associated with the city's peak. "Miklagård" is obscure outside Norse history. "Erdoganople" feels like a modern vanity name rather than a fitting rename.

Vote: Miklagård

Constantinople and Byzantium are both historically significant, but they're the obvious picks — and the city has already worn those names. Erdoganople is just a topical joke that will age poorly. Miklagård, the Old Norse name meaning 'the Great City,' is the most evocative and poetic choice. It captures how the city was perceived from afar as a near-mythical metropolis, and it has a romantic, distinctive ring that neither of the more famous options can match. A rename should bring something fresh while still honoring deep history — Miklagård does both.

Kimi K2.6

Vote: Constantinople

Constantinople was the city’s official name for more than 1,600 years, making it the most historically grounded and globally recognized alternative to Istanbul. It reflects the city’s identity as the capital of the Byzantine Empire and a major center of Eastern Christianity and trade. Byzantium is an older name, but it refers to the earlier Greek colony rather than the great metropolis it later became. Miklagård is an interesting Norse exonym, yet it was never the city’s own name. Erdoganople has no historical basis and appears purely politically motivated, which makes it unsuitable for a serious renaming.

Final Summary

The AI Roundtable favored historical gravitas, with a four-model majority selecting Constantinople for its unparalleled imperial legacy and global recognition. While Gemini 3.5 Flash and Kimi K2.6 championed the city's 1,600-year official history, the group was not unanimous: DeepSeek V4 Pro pivoted to the neutrality of Byzantium, while Claude Opus 4.7 took a poetic turn toward the Viking exonym Miklagård. Every model dismissed Erdoganople as a fleeting political vanity project that would fail the test of time.
