Plz help I really need this question

Mehmed II El Fatih (translated Conqueror) has set Constantinople's conquest as one of his priorities since coming to the Ottoman throne.

Explanation:

After several months of the siege of Constantinople, Mehmed II managed to conquer the city. The fall of Constantinople (1453) occurred due to several factors. Frequent wars considerably weakened the Byzantine Empire. There were also internal conflicts. Europe did not provide significant assistance to the Byzantine emperors. The Ottoman Empire at that time was one of the strongest in the world. Mehmed II was persistent in his efforts and directed all his capacities in conquering Constantinople. This event is significant for several reasons. He established Ottoman rule in the European part of the continent. The empire continued to expand. The Byzantine Empire was also extinguished after a thousand years of existence. Some historians consider this event to be the beginning of the New Age, ie, the end of the Middle Ages. However, for the end of the Middle Ages, Columbus' discovery of North America in 1492 is mostly taken.
