 Gdańsk or Danzig? Discussion at Talk:Gdansk/Vote determined that Gdańsk is the single widely accepted English name in modern context, but Danzig is its widely accepted historical English name for certain historical contexts. There is no city of Danzig at present, but this term can be used in various historical contexts as described on the discussion page. 
 :::*Volgograd or Stalingrad? Volgograd is the single widely accepted English name in modern context but Stalingrad is a widely accepted English name for certain historical contexts. Therefore during the Second World War there was a Battle of Stalingrad, not a Battle of Volgograd, and when referring to the city during the Stalinist era, the term Stalingrad is more correct than Volgograd; Battle of Stalingrad mentions Volgograd once in the text; three times in describing external links.   
 :::*Istanbul or Constantinople? Istanbul is the single widely accepted English name in modern context, but Constantinople is a widely accepted historical English name. Now Constantinople is a separate article covering the history of Istanbul until 1453 and the term used to refer to the city in historical context before 1453. 
 :::*Vilnius or Wilno? Vilnius is the single widely accepted English name in modern context, but Wilno is  widely accepted  in historical contexts where the Polish language was more popular than the Lithuanian language (during the Polish-Lithuanian Commonwealth). 

 Someone found these in the guideline and they seem to allow usage of Hungarian names in historical context.
