Answer:
Caravan routes seaways and highways made trade easier.
Step-by-step explanation:
Before the Roman Emperor Constantine I decided to create a new capital in Byzantium, the city had already enjoyed a long history. Byzantium was located in the Black Sea, and the fact that the city had access to the sea meant that it was an important trading port. Moreover, the city was located between Europe and Asia, and it acted as a nexus between the two continents. Caravan routes passed through the city, making trade much easier. All of these were reasons for the Emperor to establish his "New Rome" in the city of Byzantium.
