Explain the similarities of the persian empire and the islamic empire

The Ottoman Empire began from one of the small tribes established in northwestern Anatolia in 1299. It was named after Osman I (1), the first Ottoman ruler who expanded his empire into the Byzantine Empire in Asia Minor. During his reign, Osman united the independent states in Anatolia under a single rule. He also established a formal government and allowed the people he conquered to practice religious freedom. (2)

The Ottomans were Muslims and religion played an important role in the empire. (3) But, the Ottomans did not force the people they conquered to convert. In fact, they allowed Jews and Christians to worship and practice their traditions without persecution. (4) As a result, they kept the people they conquered from rebelling, which allowed them to rule for many years.
