The term "nawabs" is typically used to refer to governors or high-ranking officials in the Mughal Empire, particularly during its peak in the 18th century. However, there are several synonyms that can be used to refer to this title or position of authority. One common synonym is "chieftain," which refers to a leader or chief. "Emir" is another synonym, which is typically used in a Middle Eastern or Islamic context to refer to a prince or ruler. "Sultan" is also a synonym for nawab, which typically refers to a Muslim ruler in the Ottoman Empire. Finally, "khan" is another common synonym that refers to a nobleman or leader in Central Asia.
