The Ottoman Empire arose in Turkey during the 15th century.
Explanation:
1. The Ottoman Empire, one of the largest and longest-lasting empires in history, was founded by Osman I in the early 14th century.
2. The empire expanded rapidly under the rule of Osman's successors, especially Mehmed II, who conquered Constantinople in 1453, marking the end of the Byzantine Empire and establishing Istanbul as the new Ottoman capital.
3. Therefore, the Ottoman Empire rose to power in what is now Turkey during the 15th century, becoming a dominant force in the region and beyond.
So, the correct answer is the 15th century.
