Points of Divergence
786 AUC - A Jewish man by the name of Jesus of Nazareth is brought before the governor of the Roman province of Judea. The local Jewish priests tells the governor that the man Jesus claims to be the messiah. They also tell him that he is committing crimes against the Empire. The governor dismisses the allegations and lets Jesus of Nazareth go. Christianity dies out by 853 AUC, mostly from internal conflicts.
888 AUC - Constant uprisings by the Jews in Judea leads to a complete Roman assault on the area. Thousands are killed. The Roman massacre of the Jews is one of the worst events in human history. Many of the Jews in Europa are exiled to the lands of the North. They are supposed to have been killed off by the Northmen, Rus, and others in the area. No one really knows what happened to them, or if any survived. Their religion, at least, is extinct.
1203 AUC - By this time the Roman Empire was too large to govern, especially with constant attacks from barbarians. The Empire is split into 12 semi-autonomous regions: Britannia, Gaul, Germania, Iberia, Africa, Aegyptus, Mesopotomia, Asia, Graecia, Illyricum, Dacia, Italia.
Pax Europa and the Rebirth of Antiquity
Christianity never takes hold. Judaism is stamped out by the ninth century AUC. The Roman Empire still breaks apart, but in a more peaceful way. There is no Dark Age in post-Roman Empire Europe, but there is a period of inactivity that lasts 300 years. This is referred to as the Pax Europeana. By 1500 AUC, the regions had turned into Commonwealths. They had their own governments, but they still acknowledged the Emperor in Roma. This was also the time of the Rebirth of Antiquity. Their was a renewed interest in the ancients and their way of life. The Europans began to seek the riches of the mythological Orient. Some Europans sought help from their governments in seeking the Orient. Most took the overland passage. A few discovered a new route down the coast of the "Black Continent", Nigeria.
Iberians formed colonies in the west of Nigeria. Aegyptians formed colonies in the east of Nigeria. Gauls formed colonies in the south of Nigeria. The Greeks, though, with centuries of trading experience were the first to travel to the Orient on a sea journey. The Northmen of Scandinavia, though, attempted a journey to the Orient westward. They discovered new lands in 1702 AUC. They colonized the land and called it Vinland.
This began a race between the Europans and the Northmen to conquer the new lands. The Europan Council of 1707, called into question the Northmen's discoveries. The evidence was sufficient enough, and the Council agreed to fund an expedition from Italia to Vinland. The expedition was blown off course and landed in OTL northern Brazil. It has come to be known as Nova Roma.
While all of this is happening, the Chin are trading with the Europans and funding their own expedition to the East. The Chin soon land in OTL California. With these three superpowers in OTL Americas, the race to conquer it heats up. By 1900 AUC, the Northmen had conquered most of OTL northeastern North America; the Europans had conquered OTL northeastern South America; and the Chin had conquered OTL northwestern North America.
The Age of Confusion
Epidemics in Europa, Chin and Scandinavia led to a vast decrease in expeditions to Nova Roma (let us use the Europan name from now on to refer to OTL Americas). This lasted 200 years. The epidemics also saw a rise in more independence for the Commonwealth states. They saw themselves as completely independent from Roma.
The Emperors, though, did not give up so easily. They waged constant warfare with one Commonwealth or another. By 2166 AUC, a treaty was passed to cease all warfare and granted complete independence to all former provinces of the Roman Empire. The treaty is called Europa 66.
As the Commonwealths became nations, they fought amongst themselves for dominance. Meanwhile in Nova Roma, the Aztecs came into power in Central Nova Roma and the Incas came into power in Southern Nova Roma. Any remaining outposts were decimated by the native Nova Roman empires. The Aztecs took over western North N.R. The Incas took over all of western N.R.
Reconquest of Nova Roma
The Reconquest began in 2278. The Europan nations began to take over Nova Roma. The Scandinavians reconquered their former colony of Vinland, after it had been destroyed by the natives of the area. The Chin, though, were in a 200 year long war with the people of OTL India. They would not seek the land of OTL California until the 24th century AUC. The 24th century saw wars only in Nova Roma. The Chin attempted to avoid war, but fought with the Aztecs for the lands of western Nova Roma The Europans fought with the Incans for the lands of south Nova Roma The Scandinavians fought with the people of northeast Nova Roma for control of the area.
By the 25th century, the lands of Nova Roma and Nigeria were conquered. The Aztec and Incan Empires were reduced to mere kingdoms with not much power. The Scandinavians, Chin and Europan nations had split the lands of Nova Roma and Nigeria amongst themselves. While the Chin were more peaceful towards the native populations after a while, the Europans were ruthless to them. Most of the natives in southern Nova Roma were decimated by the Europans.
Many of the colonies in Nova Roma sought independence from the founders in the 26th century AUC, soon after the Industrial Revolution of the 2500s AUC. The independence was not granted easily, but it was inevitable. Of the former colonies, Vinland and the Confederation of Southern Nova Roma (COSoNoRo) rose to become superpowers by 2600 AUC. Vinland was more of an economic superior, while Cosonoro was more of a military superior. In 2709, the Europan nations began to come together more. They signed a treaty to bring about the Union of Europan Nations (UEN). Roma was chosen as the capital for the UEN, which began to tie Europa together economically. Scandinavia fought a war with the Rus and took over their lands. Europa remained neutral. In 2727, the Vinlandians were on the brink of a nuclear war with Cosonoro. Their political differences were the roots of this conflict. By 2745, both nations became friendly with each other.
It is now 2758, and the world is in relative peace.
