Ottoman Empire represents on of the largest imperial projects in the history of humans, ruling vast territories in North Africa, the Balkans, and the middle east over a period of some five centuries. It was created by Turkish tribes in Anatolia that became one of the most powerful states in the world during 15th and 16th centuries.  The central fact that allowed Suleiman to peruse urban renewal projects was the fact that his revenues from the state were higher than those of other European monarchs.
