In this world magic plays a big part of running things. Its likely someone as powerful and power mad as Kuja used magic heavily to coerce Queen Brahne by some sort of mind control.

Kuja in the early days managed to kick Zidane out of his original world onto the world of Gaia on hearing Zidane was a step up above him in being a genome with a better soul. So back then he already had a lot of power.

No wonder she went insane when her husband died, it was because she knew no one else would ever find her attractive.
Exactly. Even Kuja referred to her as the elephant lady. Not very flattering. I imagine she overheard similar comments. Or another sinister possibility is Kuja spread her unflattering nickname behind her back, and when he played nice in front of her, show her what everyone 'actually' thought of her, and used it to make her learn to hate and wage war.
