Wikipedia says: The Ottoman Empire was one of the lasting empires in history; such that the Ottoman State, its politics, conflicts, and cultural heritage in a vast geography provide one of the longest continuous narratives. During the 16th and 17th centuries, in particular at the height of its power under the reign of Suleiman the Magnificent, the empire was one of the most powerful states in the world – a multinational, multilingual empire that stretched from the southern borders of the Holy Roman Empire to the outskirts of Vienna, Royal Hungary (modern Slovakia) and the Polish–Lithuanian Commonwealth in the north to Yemen and Eritrea in the south; from Algeria in the west to Azerbaijan in the east; controlling much of southeast Europe, Western Asia and North Africa. At the beginning of the 17th century the empire contained 32 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. With Constantinople as its capital and vast control of lands around the Mediterranean basin, the empire was at the centre or center of interactions between the Eastern and Western worlds for over six centuries.
