Answer:
Ancient Rome was the largest city in the world during the first century. At its peak, it reached the staggering figure of one million inhabitants.
Explanation:
Rome was the capital of a very large empire that dominated the entirety of the Mediterranean Sea, and that included diverse peoples like the Egyptians, the Greeks, the Italians, the Iberians, the Dacians, the Thracians, and the Palestinians.
Rome was the main trade center of the empire, and many merchants from all parts of the empire met there, year-round, to sell their products, from agricultural produce, to exotic animals, to slaves.
During the periods of the year with the highest trade activity, the cities of Rome were very noisy, and even dirty and disorderly, but all this apparent chaos contributed to the economic dynamism of the Empire's capital.
