Regent Cid did this because he and the late king of Alexandria were best buds. and Kidnapping a princess will be seen as an act of war.
Regent Cid sent Zidane because he felt something was wrong, and he thought war was going to brew (he was right), he thought she would be safer in Lindblum, because he didn't know about the Black Mages or the Eilodons.

This wasn't the cause of the war though, and if it was, then you've missed the whole first disc.

Brahne didn't like Garent running away because she had the Eilodons, and Alexandria's pennant.

Brahne attacked, Burmecia, and Cleyra before Lindblum, because the plan was to get the Eilodons and the Pennants the entire time.

Garnet mentioned Kuja showing up a year before the storyline's beginning, meaning they planned this war a year before she ran away.

This part of the story line seemed pretty self explanatory. :P
