You might be playing the game with lots of computer opponents on small maps... which would cause this scenario.

You might not be expanding to independent neighboring provinces fast enough. You should be planning to conquer a province every other turn. Mercenaries help big time with this.

Also when you first meet your enemies don't go attacking multiple computer opponents unless you feel confident about keeping them under your thumb.
