While we are approaching 21st century gradually, there are some slight movements observed in the Balkans, the Northern Africa, Middle East, the Caucasus and the entire Islam world. The Ottoman spirit always constitutes the base for the origin of these slight movements. Therefore, the Ottoman geography should be analysed well in details. It is necessary to research the surface area, natural conditions and the role that this giant state had played on these natural conditions, its people and the secret of the integration of various peoples to live together, the administrative styles and methods, the agriculture, industry and the place of the state in the world trade. Pursuant to these detailed researchers, some consequences should be obtained for the future. Therefore, we have to combine the trio of history- geography- future all together.
