Editing Endonym and exonym (section)

=== In Eurasia ===
Exonyms and endonyms must not be confused with the results of [[geographical renaming]] as in the case of [[Saint Petersburg]], which became Petrograd (''{{lang|ru|Петроград}}'') in 1914, Leningrad (''{{lang|ru|Ленинград}}'') in 1924, and again Saint Petersburg (''{{lang|ru|Санкт-Петербург}}'', {{lang|ru-latn|Sankt-Peterbúrg}}) in 1991. In this case, although ''Saint Petersburg'' has a Dutch etymology, it was never a Dutch exonym for the city between 1914 and 1991, just as [[New Amsterdam|Nieuw Amsterdam]], the Dutch name of [[New York City]] until 1664, is not its Dutch exonym.

Old place names that have become outdated after renaming may afterward still be used as [[historicisms]]. For example, even today one would talk about the [[Siege of Leningrad]], not the Siege of St. Petersburg because at that time (1941–1944) the city was called Leningrad. Likewise, one would say that [[Immanuel Kant]] was born in Königsberg in 1724, not in [[Kaliningrad]] (''{{lang|ru|Калининград}}''), as it has been called since 1946.

Likewise, [[Istanbul]] (Turkish: {{lang|tr|İstanbul}}) is still called {{lang|el-latn|Constantinople}} (''{{lang|el|Κωνσταντινούπολη}}'') in Greek, although the name was changed in Turkish to dissociate the city from its Greek past between 1923 and 1930 (the name Istanbul itself [[names of Istanbul#Istanbul|derives from a Medieval Greek phrase]]).<ref>"The Names of Kōnstantinoúpolis". Dünden bugüne İstanbul ansiklopedisi. 5. Ciltli. 1994.</ref> Prior to {{lang|el-latn|Constantinople}}, the city was known in Greek as {{lang|el-latn|[[Byzantium|Byzantion]]}} ({{langx|el|Βυζάντιον}}, {{langx|la|Byzantium}}), named after its mythical founder, [[Byzas]].
