Iconian Wars

The Iconian Wars were a series of conflicts from 2399-2417,  though historically the Iconians had taken provocative stance before then. It was a war between several factions in the Alpha and Beta Quandrants and later the Delta Quadrant. The Dominion did have some interaction as well, though.
