For those of you who haven’t figured out how to get started as Luxembourg for fun or for the achievement, since having 0 access in a personal union is a pain.
Guide to Independent Luxembourg
Expel Diplomats vs the Dutch, dropping your relations to 20, and start hurting your relations.
Do whatever else you want to do in your run, but the two steps above are necessary.
As soon as your relations with the Dutch drops to 19, start the Independence play.
Wait until the progress gets to 70 and then invite any one power who can be bought (Likely Austria) into the play. They will surrender immediately when they realize they can’t take on Austria’s 250+your 3 battalions alone.
Congrats, you are now an independent 1 city minor who can now trade, it’s up to you to decide where to go from here.
Why/How This Works
This works because the Dutch severely outclasses your army, so it doesn’t feel the need to bribe anyone to help.
Therefore, you take advantage of the 9 tick delay the ai(or everyone, I dunno, I’ve been playing nothing but Luxembourg so far) has for accepting bribes for plays to make sure they can’t get anyone to help them vs Austria.
There is a phase progress pause for 5 days/ticks but because of the info above, the Dutch can’t invite anyone in time, usually Prussia.
