I can make a better alternate history my opponent

Here you go. A showing of how the balance of empire can flux. i think I may have to do it in 3 parts as it truly is an epic. 300 BC: An obscure law is passed tightening restriction on the destruction of any fortress in the roman republic. Beyond your omniscient narrator it is unknown to history. 218-195 BC: Hannibal surrenders himself to the Romans due to his father's famous blood oath not existing thanks to the fact he was made dumb after an arrow from a fortified tower. He is kindly escorted to the palace where he and his rival general Scipio Africanus become good friends. Hannibal's legions will be used to take control of most of Gaul. 191 BC: Hannibal is allowed governorship of Carthage as a separate vassal of Rome, (similar to what Byzantium would be.) 185 BC: Hannibal is assassinated along with his son who's own child Honorius Ba'al is unfit to rule due to the fact he's a few months old. Regents friendly to Rome take control until he is mature at 16. 172 BC: Before the upstart Honorius can gain power his regents make Carthage a full roman province yet the political situation stays roughly the same. 138-136 BC: After years of taxation Hannibal's grandson Honorius Ba'al assembles a secret elite team of soldiers to declare an independence of sorts. They dispatch of any occupying imperials and conquer up to Gaul. 135 BC: A think-tank of generals pushes Honorius to lower Spain where a massive fortress in what is now Narbonne. Like Hadrian's Wall it makes a boundary which contains Carthage yet is occasionally conquered by both teams with elaborate walls and traps built on both sides. Due to the very first point in the time line the Romans can't destroy the defenses on their side. The Carthaginians gleefully pick-up roman Ballistae and nail them to their own fortifications. Knowing the Romans won't be able to pull them down. 70 BC: Carthage stops expanding south to Africa. It is a solid line as far south as Algeria yet leaves the eastern border such as what is Ethiopia and Egypt alone. 44 BC: Due to lack of roman interest in creating a "Roman lake" after Ceaser's assassination Mark Antony never comes even close to Cleopatra and instead becomes Ceaser's successor, lying about a relationship between the two, which will go down in history as true. Egypt is never attacked but becomes a pacifist nation carrying Ceaser's blood and becomes an extremely close ally with it's "Brother rulers." Cleopatra's dreams of conquest though, are never realized as the aging queen leads instead a pacifist trading state. 37: Jesus of Nazareth is not crucified by Romans (who honestly don't care about such far off colonies and around this time meet their peak northern border just south of Scandinavia) but instead is stabbed to death by Judas Iscariot. Although persecuted Martyrdom is much rarer as Christianity thrives in Judea and much of the middle-east, moving to Europe much slower and steadier, yet becoming roman state religion in about the same manner and time span. The fish becomes the de-facto symbol of Christianity although the knife of Judas and star of David are popular religious symbols. 75: The Egyptian and Carthaginian borders converge at Tripoli and Chad. War is started and Khopeshes are often seen on horseback raiding Carthaginian caravans or vice versa. 150: Ethiopia is introduced to Christianity where it becomes state religion as much earlier than the standard time line as it has become a wealthy, more globalized trading giant with Egypt. They repay the favor by leading the occasional sack of an Egyptian city for its wealth and soon become powerful enough to rule most of the horn of Africa and eastern Sudan. 180-197: The world famous roman voyages of Dominicus start. He voyages to India and Persia with several tons of metal trinkets and sells them to local rulers for many times their worth in raw materials. Interest is raised in trading and middle-easterners become more efficient in war from copying down European plate armor and the image of an Arab warrior morphs from a cloth laden rider to an insidiously intricate armor set marching into formation with fast horseman circling the enemy. 237: After immense popularity in Italy, Christianity is declared a state religion by Caesarian Aurelius Antonius although some form of a papacy has already been erected in Jerusalem. Christianity is never associated with Rome or the Latin language but rather Aramaic. Due to a lack of martyrdom the church is far different from Catholicism and guilt is rarely present. Original sin ceases to be a theological idea. 239: The Egyptian royal family of Ptolemy, being close "relatives" converts to Christianity also. The Ethiopian war ceases due to common belief and a crusade against Carthage is due. 241: First roman soldiers pass their Spanish border and "liberate" the (now indistinguishably Carthaginian) Iberians. Opportunistic Scandinavians raid the German outposts and the roman front falls as all the soldiers retreat to save their families. Similarly the Ethiopians and Egyptians attempt attack but are beaten off as Roman reinforcements fail to come. If anything Carthage gains territory while the Allies lick their wounds. 265: Egypt joins the Roman Empire, still recognized as a foreign state the two nations share an economy and have open borders. Germania and Britain succeed in getting a similar privilege, roman consuls ruling Britain and the Germanic head tribes being reinstated with a new political role. The core roman empire consists of Gaul, Southern Germany, Greece, Italy, Eastern Europe and an insignificant part of Spain. Egypt is given the western edge of Arabia and Anatolia as a gift. 290: Carthage recedes its southern border after coming to the conclusion there is nothing but desert. They in fact stopped just before a large range of temperate forests and mines. They have already displaced several African tribes south or brought them home as slaves. None of the west African peoples such as the Mali are to come to be. The area is essentially barren. 290-320: Ethiopia takes advantage of a niche and conquers the area abandoned by Carthage. Carthage is essentially boxed in, leaving no room to expand and they desperately send ships out to the Mediterranean. Some are raiding parties; a few conquer the rest of Spain so coveted, while the largest forces conquer Sicily. They occupy it for a few decades but are repelled. With no threat beyond the occasional eastern or Scandinavian raider they push to Spain but the fortress at Narbonne is impassable due to a barrage of Ballistae fire. 300: To commemorate the 300th year of our lord, Rome admits Ethiopia to its empire as a distant brother and a society academics call the western union is born. To be more manageable Ethiopia splits into 3 roughly equal parts, the farthest west consisting of troublesome territories is strip-mined of resources and left to its fate. It allies with the Carthaginians. 375- 425: Huns attack marching to Rome through eastern Europe in blitzkrieg fashion staving off soldiers to all of eastern Europe, Greece, Northern Italy and a good portion of Germany. The soldiers rally with the eastern empire and lead a reconquest, permanently leaving these provinces to the east while western Rome is left with the table scraps. The Huns rotate to china where they renovate the great wall to a uniform barrier. These vermin are dissolved in a matter of decades and Asia is safe for a matter of centuries. 0 characters at the end of this sentence.
