Final answer:
The Polos escorted the princess to Constantinople, a city historically important as the capital of the Byzantine Empire and a key trade hub between Europe and Asia.
Step-by-step explanation:
The Polos escorted the princess to Constantinople. The city of Constantinople, strategically located as the gateway between Europe and Asia, played a significant role in history. It was the capital of the Eastern Roman Empire, also known as the Byzantine Empire, after Emperor Constantine moved his government there in 330 CE. The city's strategic control over the Bosporus and the Dardanelles made it crucial for trade between the Mediterranean and the Black Sea.
After the Ottoman Conquest, Constantinople was a potent symbol of East/West trade and power. The Polos' journey to escort the princess illustrated the interconnectivity of different regions during that era, where alliances and marriages were often used to strengthen political and trading ties.
