- Won reformed Romuvan Great Holy War for East Francia (fought against King Nikolaus II)
- My (unlanded) Wife had a claim on the Kingdom, so was given all the counties.
- However she was not given the Kingdom title, (that remained with King Nikolaus II), and instead she became my vassal.
- On the same day the war was won, King Nikolaus II usurped the County of Bamberg (de jure East Francia) from my wife.
- She gained a strong claim on the usurped County.
What mechanic is it that allowed the loser of the Great Holy War to immediately usurp one of the winner's counties?
