Over time, the Roman Empire grew ever larger, encompassing most of what is now Europe and large parts of the Middle East. Peoples from those countries were assimilated into the Empire as Roman citizens. Their resources further enriched and strengthened the Empire.
A significant addition to the Roman army were Germans who although discriminated against at every level, proved to be more than capable as soldiers and officers.
A young German found favor with a high ranking Roman officer after saving his son from drowning, Ultimately, that youth, Alaric, also found favor with the Emperor. He faced adversity on several levels but persevered to become a highly respected general.
Forces within the Roman Senate and a high-ranking general planned to take control of the government by disposing of the Emperor and replacing him with the Emperor's young malleable son.
The Emperor was poisoned, his young son established as the pseudo Emperor, and control of the senate and army controlled by a chosen few.
However, their growth reached a peak and the resources that had been utilized and shared throughout the Empire began to decline to the point that many outside of the Empire’s core, Italy, began to suffer from malnutrition. The senate in Rome promised needed resources time after time. However, if any were distributed they were of insufficient and/or poor quality.
Where once everyone in the Empire celebrated the richness of its many treasures, those outside of Italy began to suffer winters without the supplies needed to maintain a modicum of comfort and warmth.
The new leaders of the Empire held the Germans in poor regard. They had been preventing them from achieving positions of power and enjoy the same pleasures as Italian citizens of every caste.
Jealous of anyone related to any, other than Italian, the new regime began to discriminate in many ways, often violent, including torture and death.
Once, proudly loyal to the Roman Empire and its army, the Germans having been stationed outside of Italy, grew first saddened and then angry.
Finally, the Germans developed their own government, independent on Rome, and Alaric, already a respected and seasoned leader, was established as their General/Emperor.
Alaric amassed an army large enough to march confidently into Italy and headed for Rome.
Often, as they marched through Italy, citizens and Roman soldiers alike, turn their backs of the Germans, signaling their acknowledgement of the terrible actions against so many non-Italians and offering safe passage.
Upon reaching Rome, Alaric's army set up a siege. In time, the gates opened, and the German army entered. Under strict orders from Alaric, no peoples or buildings were to be harmed, and it was strictly enforced.
They took only what had been promised, whether, gold, jewels, food, seeds, armaments, or cloth. Then, returned to Germany.
