Exactly. I'm surprised this is even an issue. It
would beyond silly to
only
refer to Leningrad as Saint Petersburg in a separate
article dealing with
the
history of the Soviet Union. Likewise it would be very
odd to refer to the
United Kingdom in an article about the Norman Invasion. Gaul/France along
with Constantinople/Istanbul are other examples (as would be
Londinium/London, for that matter - Peking/Beijing is a different matter
dealing with a change in the accepted English transliteration).
Another datum: [[Newfoundland]] refers to the island, and [[Newfoundland and
Labrador]] the province; when I set this up, I went through all the articles
that mentioned Newfoundland, and those that were historic references to the
colony, dominion, or province (under the then-correct name "Newfoundland"),
I changed it to [[Newfoundland and Labrador|Newfoundland]]. That seemed
fairly reasonable.
