@SmashedPotatoe: Your English is just fine, quite good in fact. Do you have a save-game which predates pardoning Rogan? I'd say - if you have - go back and this time either kill him or lock him up. Rosha has been MIA for quite some time, and I never finished a game in Wedding Dance while helping out making it and beta testing it. If my suggestion won't work, I fear I can't do other than speculate. Also, remember this is still a beta version of Wedding Dance, as Rosha didn't finish it yet.
Another possibility is that you cannot truly win the game until ALL lords are your vassals. If you still have a lord on the loose,
hiding out at a castle, lurking in some obscure corner of the map, etc. or even a stray caravan not of your conquered faction, the game does not register that you have "finished it." This may well be the case, and I'd recommend catching Queen H at once. Don't lock her up - keep fighting, catching, releasing her until she joins you. Once she joins you, wait a week or so in gametime - go whack some bandits or Sea Raiders or something, and see then if you are not declared a victor. There is a very delightful victory ending cut scene that Rosha did a lovely job on in Wedding Dance, and I'd hate for you to miss it.
There is one final possibility: there is a bug in the codes for the Claimant Quest in M&B (predates V .960 and carries through all the later versions - Taleworlds never fixed it and to my knowledge a modder can't fix it.) This bug affects M&B in much the way it appears your game has come out. It does not always turn up, but does so often enough to be worth noting. (We have the same problem in Prophesy of Pendor - the Claimant Quest is sufficiently bugged in our mod that we just advise people not to play a Claimant Quest in any of the PoPs.) If I'm not mistaken, Rosha used some of the Claimant Quest codes and modified them in Wedding Dance. It is possible - and this is pure guessing as I'm not a coder - that something in the vanilla Native Claimant Quest code may have bugged your game.
