The correct answer is C) Byzantine Empire.
Most of the land occupied by the Ottomans had been part of the Byzantine Empire.
After the split of the Roman Empire into the West Roman Empire and teh East Roman Empire, many years later the East became the Byzantine Empire with its capital in Constantinople, modern-day Turkey.
The Byzantine Empire occupied the territories of the Mediterranean Sea, Turkey, Italy, Greece, big portions of the Middle East, and North Africa.
In the 15th century, the Ottoman Empire defeated the Byzantine army and captured Constantinople.
Osman was the founding leader of the Ottoman Empire. History says that he had a dream. In that dream, a spiritual figure called Sheikh Edebali appeared. Osman could envision how he led his troops through many parts of Europe, Africa, and Asia. In the dream, Osman envisioned mountain ranges such as the Caucasus, the Danube River, and the North African region with the Nile River. His vision reached places in the Middle East such as regions between the Tigris and Euphrates Rivers.
