For this question you need only to know what the capital of the Byzantine Empire was: it was Constantinople, this should be the correct answer (I hope it's in options).
Today this city is known as Istanbul, and it's the biggest city in Turkey.
As the population of a civilization grows, it struggles to provide resources for the population. One of the easiest solution to this is to expand their territory in order to amass more money and power by taking the resources of others instead of producing their own.
Some expansions of territory lead to conflict but not always, there are countless ways to forge peace and harmony by sharing learning and the promise of stability by strong leaders.
