Considering a couple of random ideas and that old perennial alternative history favourite Burgundy came up. One of the instinctive objections I have against a surviving Burgundy though is that it would probably butterfly the eventual Netherlands who I have something of a soft spot for. Would it though? Now I know very little about the area during the time period but one of the reasons why the Dutch were successful I thought was that they were removed from Spain and her possessions with only the sea for them to send the majority of their troops to suppress the rebels. Well that and the Dutch being typically stubborn.
A Burgundy that's somehow survived, insert handwavium here for the moment, and also acquired Lorraine to link all their territory can just march their troops about through their own lands. On the plus side however they'd be faced with a smaller enemy with less financial and manpower resources. So could what became the Dutch Republic somehow have a chance of rebelling against a Burgundy that has somehow managed to anger them enough?
