The establishment of the Ottoman Empire by migrant Turks in Asia Minor is an interesting and prominent event in the Muslim World. The wise policy of the Ottomans in confronting the powers around and the blending of various ethnicities with different races and languages looked astonishing at the first glance though it weakened their empire in the long run. After the 10th century A.H., 16th AD, the empire fell on a path of decline; however, the final fall came very late. The writer of the paper intends to prove that although the period of Suleyman the Lawgiver looked magnificent, it carried with it factors of decline and disintegration. From the viewoint of the researcher, Suleyman wanted to overcome the world that had begun its transformation through internal ways and means. He adopted improper policies in a decisive period of the world; policies which in long term caused the fall of the Ottoman Empire.
