Historical Figures

When discussing the oldest Roman city in Germany, it is important to consider the historical figures who played a role in its founding and development. One of the most significant figures is Emperor Augustus, who founded the Roman colony of Augusta Treverorum in 16 BCE. This colony later became known as Trier, which is considered the oldest city in Germany and the first city in Germany.

Another important figure is Constantine the Great, who was born in Naissus (modern-day Niš, Serbia) but spent much of his early life in Trier. Constantine was proclaimed Western Roman Emperor in 312 CE and is known for his role in legalizing Christianity and founding the city of Constantinople.

During the late Roman Empire, Trier was an important administrative center and residence of many Roman emperors. Maximian, who co-ruled as Western Roman Emperor with Diocletian, spent much of his reign in Trier. Diocletian himself visited the city in 293 CE and is known for his administrative reforms, including the division of the Roman Empire into two halves.

Another significant figure in the history of Trier is Constantius Chlorus, who served as Caesar under Maximian and later ruled as Western Roman Emperor from 305-306 CE. Chlorus was known for his military campaigns against the Franks and his efforts to restore order to the Roman Empire after the Crisis of the Third Century.


Economic Aspects

An important economic factor to consider is the euro. Germany is a member of the European Union and uses the euro as its currency. This means that if you’re visiting the oldest Roman city in Germany from another country, you’ll need to exchange your currency for euros.

While this can be a bit of a hassle, it’s important to remember that the euro is a stable and widely accepted currency that makes it easy to travel throughout Europe.
