Gdansk / Danzig led
the Prussian Confederation which asked
King Casimir IV to join Poland in 1454 and allied with them against their former overlords in the Teutonic Order. The treaty was signed in Danzig. I'll quote from the wikipedia page since you like to use it as a reference:
"After about three decades of growing discontent, the Prussian leaders (see Prussian estates) organized themselves to oppose the rule of the order more effectively. On 14 March 1440, a group of 53 gentry and clergy and 19 Prussian cities, under the leadership of the Hanseatic cities of Danzig (Gdańsk), Elbing (Elbląg), and Thorn (Toruń), founded the Prussian Confederation in Marienwerder (Kwidzyn). Several more towns joined on 3 April, although Bütow (Bytów) did not. In Danzig, the new members signed a document which was kept in the archives of Thorn."
" Gabriel von Baysen and Johannes von Baysen, now leading the confederation, requested the protection of King Casimir IV Jagiellon of Poland. They also asked for, and received, a guarantee of their continued city rights and privileges for the gentry."
The same thing happened many times before with Hanse cities. Riga allied with the Lithuanians in 1297 to get out from the oppression of the (German) Teutonic Order.
What Hanse towns went voluntarily to Poland???
All of the ones in Prussia, to start with. See the links above.
Are you confusing things here?
No I think you are a little confused about this period of history.
You really should read up about the Hanse....
Just in short...it was a GERMAN merchant organization....with GERMAN as official trade language under GERMAN law...barely were any non-germans allowed in.
It was a bit more compex than that....
And it was the
Holy Roman Empire of the German Nation...so, what do you think...
I think the HRE included subjects of every central European race, including Bohemians, Poles, Italians, Swiss, Flemmish, Frisians, Burgundians, Hungarians, Moravians, Wlachians and numerous others during it's history. More importantly, it's ruling class included Aristocrats from many other parts of of Europe including Spain, Bohemia, Hungary, Poland etc. etc.
I also don't think you know much about it. But that's ok, neither did I until I read a few books.
