Answer:
complex and effective.
Explanation:
As was typical of the Muslim tradition, in its expanding phase, every sultan emerging from the leadership of the Turkish-Ottoman Empire needed to demonstrate its authority by conquering and subjugating other peoples in order to further expand territorial dimensions. In this sense, the main conquest undertaken by the Ottomans was that of the city of Constantinople, the center of the Byzantine Empire, also known as the Eastern Roman Empire, the most powerful empire of the Middle Ages. This conquest took place in 1453, when Constantine XI Palaeologus ruled the Byzantines. The Turkish conqueror responsible for the fall of Constantinople was Mehmet II, who turned the city into the center of his empire, giving it the name of Istanbul, which remains today.
