Explanation of the changes 1 There was revert war over Gdansk Danzig Danzig Gdansk is a compromise which was supposed to stop such revert war ridiculous take a look on article history It is article about Polish German painter yet the last 50 changes were edits changing Gdansk to Danzig and vice versa 2 Danzig is nt just German name It s also name by which still the city is known in English world although the fact probably will change in the future Therefore it s reasonable to mention both names 3 There is no such case i believe with Frauenburg It s small city so there is no point in making alternative name too
