Schleswig goes back in time

  Had overlooked that Heligoland was included in the ISOT.  Good point although strictly speaking Germany doesn't exist at this point.

  With a 1-1-1860 date for the up-timers to arrive the big factor will be news of future events, probably most immediately Bismarck's wars and the defeat of Denmark, Austria and France which is going to affect the actions of all those powers and probably make them look a lot more carefully at Prussia.  Could even result in pressure that Bismarck never actions becomes a prominent politician?

  Similarly when news crosses the Atlantic what will the US make of Lincoln winning the forthcoming election due to a divided opposition and the civil war that follows.  Do the Democrats get their act together to win the election.  If Lincoln still gains the Presidency what does the OTL south do?

  There will be a lot of other events coming up including the Anglo-French conflict with China - often inaccurately called the 2nd Opium War - and numerous other events across the world. 

  I suspect that events beyond the next couple of days are likely to be less important to the down-timers as they will seem too distant and alien.  Mind you ideas like racial equality, equal rights for women, let alone homosexuals and the ending of colonial empires and the fall of the bulk of the autocratic states - albeit to be replaced by even more autocratic ones in Germany and the Russian empire will set a lot of the powerful thinking. 

  Technology transfers will be a factor as well.  While the region affected might be too small to maintain the technology its gotten it will be able to support some and the sheer knowledge, such as details of medical advances and how to control/combat many diseases or simply the dangers of smoking could change a lot over the coming decades.

  Would they want to.  1860 German Confederation doesn't have even adult male suffrage let alone a lot of the other civil rights that the 1990 west will take for granted.  I suspect the overall reaction will be we're better off together with the affected areas forming a loose confederation that insists on being neither Danish or German.  And in the short term at least they have the power to make it stick. 

  Well 1990 was less centralised in technology so they might be able to maintain a lot of stuff although the more advanced machinery is likely to have a limited lifespan, especially anything with advanced electronics especially computers and aircraft and the like.  Depends on what the area could support at that time.

  The bulk of it is still there with equal rights for women and minority races and while homosexuals may still be somewhat restricted their allowed to openly exist.

  I agree those are the areas where tech transfer and related knowledge are likely to be the most important.
