The definition of an empire is: when a single entity has supreme rule and power over a vast area of territory, which consists of peoples of different ethnicity and nationality. This list is based on the influence, longevity and power of the various empires, and, as you will see, it contains at least one or two entries that may strike some as controversial. My one requirement for this list is that the empire must have been ruled – for at least a majority of the time – by an emperor or king. This excludes modern so-called empires such as the United States and Soviet Union. The entries here are listed roughly by influence and size.
10. Ottoman Empire
Ottoman-Empire-Public-DemoAt the height of its power (16th–17th century), the Ottoman Empire spanned three continents, controlling much of Southeastern Europe, Western Asia and North Africa. It contained 29 provinces and numerous vassal states, some of which were later absorbed into the empire, while others were granted various types of autonomy during the course of centuries. The empire was at the center of interactions between the Eastern and Western worlds for six centuries. With Constantinople as its capital city, and vast control of lands around the eastern Mediterranean during the reign of Suleiman the Magnificent (ruled 1520 to 1566), the Ottoman Empire was, in many respects, an Islamic successor to the Eastern Roman (Byzantine) Empire.
