Roma Delenda Est

The point of divergence of this timeline is that Publius Cornelius Scipio was killed instead of wounded in the fight near Ticinus, and Sicipio Africanus wasn't allowed to go to Africa (much like in Delenda Est, but there, they both are killed by time travelers). This allows Carthage (Carthago in this timeline) to win the second Punic war, or Phoenician war as it is called in this timeline.

Roma Eterna?
After Hannibal Barca (also known as Hannibal the Lion, Hannibal the Great, Hannibal the Conqueror, and Hannibal of Roma (but some consider that a degorative term) conquered Roma in 210 BC, the second Phoenician war was over. Carthago had won, and the Imperium Romanum was no imperium anymore, for its caesar and parts of its senate had been killed. Indeed, Romanum crumbled and fragmented into competing city states, and Hannibal urged the Barca family to send more troops to Romanum. While the council and the suffits were against it, they were a minor power, for the Barca family ruled Carthago, and Hannibal finally got reinforcements. Eventually, the Romanum peninsula was occupied by Hannibal and his troops, and others, and slowly the core of the imperium became part of Carthago. The allies of Carthago were rewarded, and those who had joined or helped the imperium were hunted and destroyed. But while the core of the imperium had fallen, various cities had formed alliances and pacts with each other, and the possessions in Hispania were threatened by this. In the Romanum peninsula, there were many troops to keep the peace and thus no one dared to move against Carthago there, but in Hispania, only a small amount of troops were located. That is why Hannibal and his new army was sent to Hispania, to conquer the resisting city states. The city states, which had no legion and only a few professional soldiers, were no match for Hannibal and by 220 BC, Carthago was a giant super power. The tribes in Europa didn't invade Carthago's possessions in Hispania or the Romanum peninsula because they were friendly towards Carthago, and some even allied with them and helped them to defeat the imperium. And while Graece eyed all this with a wary eye, there seemed to be no army coming towards them. Carthago merely resumed trading and doing like it had done before the imperium declared war.
