No further edits should be made to this page.
@Peltimikko: could you reword the hook? Piping Turku in Finland to History of Turku is a WP:EASTEREGG, which should be avoided, you could, instead, pipe medieval Turku to History of Turku. Also if you want to include a picture you need to add something like (Turku Castle pictured) after the link to the subject. I would trim the picture caption to just Turku Castle.
I have asked some content questions on the article talk page.
I have checked all the online references, could you check the Statistics Finland one as I got a 404 page not found message. I have added two citation needed tags where sentences were not supported by the reference which followed them. TSventon (talk) 20:20, 16 October 2023 (UTC)[reply]
👉 Content and sources added. Fixed Statistics Finland. Offline problem is hard to avoid as the subject is not very common, but I tried to added as much online side content as possible. Unfortunately, reliable English sources are scarce.
👉 DYK alternatives: ... that Turku (Castle pictured), situated in Finland, was the second-largest city in the medieval kingdom of Sweden? or ... that Turku (Castle pictured) was the second most important town in the medieval kingdom of Sweden?Peltimikko (talk) 22:15, 16 October 2023 (UTC)[reply]
@Peltimikko: links to Wikipedia articles should not be surprising (AKA Easter Eggs), so [[History of Turku|Turku]] is a bad idea. I suggested [[History of Turku|medieval Turku]] as an alternative.
Could you provide an alternative hook? The article is quite long and there must be more facts which are suitable for the main page.
Offline and foreign language sources are allowed, I can read Swedish reasonably well and use Google translate to get an idea of online Finnish. TSventon (talk) 23:12, 16 October 2023 (UTC)[reply]
In the alternative hook, every year probably needs to be almost every year. the YLE source says the tradition goes back to Birger Jarl in the 14th century, which should be the 13th century, over 700 years ago. I suggest linking the subject as [[History of Turku|over 700 years]] as the Christmas Peace is modern as well as medieval. TSventon (talk) 20:59, 17 October 2023 (UTC)[reply]
The declaration of Christmas Peace in Turku in 1965. 👉 It seems that the peace truce during Christmas has its roots in Birger Jarl of Sweden. However, the tradition of the declaration started in Turku (Österland) in the 14th century, or 1320s, depending on the source. So perhaps more than 50 years after the death of Birger Jarl.
👉 Alternatively, you can use this picture.
👉 edited DYK suggestion: " ... that the city of Turku has declared a Christmas peace almost every year for over 700 years (pictured).
Peltimikko The DYK hook needs to be true and be included in the article with a reference. 1320s to 2023 is about 700 years, as the exact start date is not knowm. The 1320s should be included in the article, together with the reference which supports the 1320s. If the reference is offline, a quote of the relevant sentence and a translation of it would be useful. TSventon (talk) 20:33, 18 October 2023 (UTC)[reply]
👉 As this article explains [1], things are not simple: "It is certainly a medieval custom although we lack original sources from the town of Turku that would definitively confirm when the custom was established or that it indeed has been uninterrupted. However, we can contextualize this with evidence from other Swedish medieval towns with surviving later-medieval court records. "Peltimikko (talk) 20:45, 18 October 2023 (UTC)[reply]
Peltimikko, I will leave the alternative hook due to the sourcing problems. I have edited the original hook to deal with the Easter egg link, I hope that is acceptable.
Moving on to the review, I am approving the original hook as amended. The article is new enough long enough and well written. I didn't find any copyright violation and the article has sufficient citations, assuming good faith on offline sources. The hook is sufficiently interesting and cited. This is Peltimikko's first nomination, so no QPQ is needed. TSventon (talk) 20:19, 23 October 2023 (UTC)[reply]
Turku is an officially bilingual city, with both Finnish and Swedish being used. The Swedish name was the first to be used, with the Finnish name appearing later in the Middle Ages. Origin is from Sweden and Russia. Additional content has been added, with sources, to the main article about Turku. Turku - Wikipedia
Corrected. Bishop of Finland. Finlandensis episcopus
There is no literal document, but I added content and a wording from a (Finnish) book source almost certainly; a degree of historical certainty.
Thank you for the explanation, however the content added to the Turku article seems to be copied from the website, which would be a copyright violation and not permitted on Wikipedia. I now realise that surviving texts in Finnish are almost all post Reformation, so any mention of the name Turku is also likely to be post Reformation.
