In the year 476 A.D, Orestes, father of Romulus Augustulus (Roman Emperor at the time) decided himself that Rome should give the Heruli, Scirian and Turcilingi mercenaries a third of Romes Italian province, instead of possibly losing Rome them. With this came the rise of the Ostrogothic Kingdom, ruled by Odoacer. Romulus still ruled until 479 when his father took full control.
Rule of Orestes (479-502 A.D)
Orestes ascended to power on the 13th of May 479, when Romulus was killed in a assassination. Orestes made sure the relationship between Rome and the Ostrogothic Kingdom was healthy as he needed to keep Rome alive. Although the province of Gallia Narbonensis was lost to the Ostrogoths, he regained parts of Raetia, Noricum and Pannonia. Political diplomacy helped relations between the Eastern Roman Empire which lead the Eastern Romans giving Rome troops to take back their old territories. With this came the destruction of the Ostrogothic Kingdom and the beginning of the Reconquest period. The capital was then changed back to Rome (from Ravenna) in 485 A.D. Orestes died from unknown causes in 502 A.D. His grandson Romulus Augustulus II became the emperor.
Reconquest Period (489-524 A.D)
After the quick fall of the Ostrogothic Kingdom came the invasions of the Burgundione tribes. Corscia and Sardinia were regained in 498 A.D with puny efforts of Vandal Kingdom. In 508 A.D the Burgundiones were finally expelled and the Romans fought their way back into Lugdunensis, where the Franks were starting up the Frankish Kingdom. In 524 A.D Rome finalized their northern borders around those of the Visigoths and Franks. But in 527 A.D both Roman Empires had a conference about their positions and decided that when two of the imperial lineage may wed, then the Imperium shall be one again'. After the conquests the provinces regained were: Narboensis, Raetium, Pannonia, Corisca, Sardinia, Germania Inferior and Lugdunensis (partially).
Prosperity and the 'Bello pro Christo' (534-696 A.D)
In 534 A.D, Orestes II, son of Romulus Augustulus II wed with Vigilantia, sister of Justinian I causing the recreation of the Roman Empire. This new empire had nearly the same borders as Republic used to. The empire had dual capitals which helped in stabilizing the empire. Then the greater empire had a century of peace and prosperity. Rome quickly regained the provinces of Africa Proconsularis, Mauretania Caesariensis and Mauretania Tingitana which came an end to the Vanda Kingdom (although some the Legacy Vandal Kingdom remained in southern Iberia). This prosperity ended with the Arab Expansion between 635 and 800 A.D. Aepgytus and Arabia Petraea fell by 639 A.D. The Romans counteracted with their huge mercenary Germanic Armies gained from Gaul. This falted the expansion of Islam into North Africa and Anatolia. These wars were known as 'Bello pro Christo', the wars for Christ. This lasted for nearly 70 years. Finally the Muslims were expelled, looking forward to India and the Sassinids to war on. In this process the Sassanid Empire was destroyed, and looking for more hospitality, their remnants migrated north into the Caucasus.
Stable Period (696-1066 A.D)
After the end of the Bello pro Christo, the Roman world started to settle. Wars were uncommon. Vikings 'visited' Rome, but were stopped indefinatly by the 'Greek Fire'. Most Vikings were hired as mercenaries, although others were just annoyance. The Kingdom of Francia formed over the Frankish Kingdom creating prosperity north of Roman territory. Rome went more well off instead since Francia was battered commonly by the Vikings. The Visgothic Kingdom reformed into smaller states. Germanic Kingdoms also formed around the borderlands of Rome and in Britannia. But in 1066 the Normans invaded Italy from sea.
Norman Wars (1066-1176 A.D)
The Normans brought a change to Roman life. They battered down Roman military. The Greek islands and Sicily were overrun by them. Emperor Justin III made deals with Francia to obliterate them off the map. Alt hough they were successful. The Normans set up kingdoms in the Baelares and in Britannia. They commonly feuded with other nearby states but were watched closely by the Francian and Roman Military. The Roman world was now safe from the Norman menace.
Medieval Era (1176-1476 A.D)
By 1200 A.D. Rome was more technologically advanced than any other nation. But the Empire was struggling with ethnicity. Around half of the citizens mother tongue was not Latin or Greek. The once Classical nation had become very Germanic. The approach was allowing other languages to be officially recognized. Constantinople had become the economic centre of the known world with almost five million people living within its urban proximity. Trade had been well since the peace treaty with the Muslims. But when the Mongolian Khanate invaded Roman territory, Rome held them off fairly well. Only losing eastern Anatolia and Crimea to the Mongols. This caused panic among the citizens of the empire. The Emperors control was weakening too. There was five unsuccessful emperors in a row after Justin III. There was riots, uprisings and civil crises. The governers of most the provinces decided to overthrow Emperor Constantine IV in 1476 A.D ironically the milleniel of the establishment of the short-lived Ostrogothic Kingdom.
Imperial Age (1476-1775 A.D)After the overthrowing of Constantine IV, the new Senate was formed by the governors of all the Roman provinces. They decided on giving each province its own governmental systems, but left most the laws in their places. Roman citizenship was much easier to gain and slavery was abolished. Then came the Imperial Age. The Senate ordered that there should be explorers sent out on the ocean to find more rare materials and probable colonial sites.
In 1482 A.D, Julius Romunav was sent by order of the Senate to explore to new lands. After hearing the legends by the Icelandic Vikings colony on a western continent, he sailed out west out of the Pillars of Hercules (OTL Straits of Gibaltar). He was using a traded Norman longship, known for its sturdiness (later to become Romes basic naval ship). He found the Oretes Islands (OTL Caribbean), returned home with natives to show to the Senate.
The Senate were pleased. They employed a mercenary Norman fleet and Roman naval officers to set out on conquering this new land. The fleet found the mainland of Romae Occidentali, and founded the city of Tertius Romae (later known as just Tertius). The Normans were given a small portion of the continent up the coast from Tertius. From Tertius they expanded north to find the Occidentali Seres (Eastern Chinese (To the Romans they looked fairly similar)), which seemed to be very hostile. They bordered off their colony around the east coast of Romae Occidentali. The innards became the true frontier.
In 1567 A.D Romae Occidentali became an independent state loyal to the Roman Empire. The Senate created a secondary Senate in Romae Occidentali. Rome now was the wealthiest and densely populated nation on the planet. In 1602 A.D the Francians set up a colony in Romae Occidentali called Colonie de l'Ouest, which was on the northern borders of Norman territory and south of Icelandic colonial territory. The Icelandic colony had not met western civilization in nearly 200 years (the collapse of Viking Greenland).
By 1775 A.D Romae Occidentali had conquered all the way to the great Western ocean. Their nation had more than 50 million people inside its borders. In Europe Rome had become a leading power, controlling the largest Military in the world and the largest population of 134 million people. Rome was trading with most nations of the world including the tribal nations of Terra Australi.
Modern Period (1775-Now)
In 1800 the Roman Republic showcased electric power, created by its amazing Greek minds. The partnership of Romae Occidentali and the Roman Republic was extremely powerful. Francia was following behind them in greatness. By 1900 the Republic had colonies in Terra Australi and Africa Maior. These colonies together contained around 30 million people, while Rome itself contained a stagnated 140 million citizens. But in the 20th century the great war occurred. Although Rome was not much effected by the events, the other Germanic states suffered badly. In 1945 the Romans invented the nuclear rocket and were launching men into space by 1954. The world today is very ubranized and many people are migrating to the colonies on the Moon and on Mars. Our planet is very electrically powered, and without it we wouldn't have the great Space colonies and skyscrapers as we have today. Constantinople, the largest city in the world, houses 13 million people. Interstellar space travel technology is now being heavily researched and renewable energy sources as well. The sea level is 48 metres higher than what it was 100 years ago.
