Ba'al's Domain was among the last of the domains to fall. With the formation of the United Alliance of the System Lords, Ba'al's domain expanded very quickly. After the disappearance of Anubis, Ba'al established control over the Kull warriors. He used them to conquer the rest of the System Lords, but soon came into conflict with the Replicators. Ba'al's Domain collapsed with the Battle of Dakara, but it had expanded with his power until he contained most of the fallen Goa'uld domains.
