As it is known, humanity has always preferred to live in unity and civilization. Seeing the advantages of this union, humanity did not fall behind in maintaining this habit and established their own civilizations. There are many empires and kingdoms in history. Even though most of them have been forgotten, the British Empire, the Mongol Empire and the Austrian Kingdom have written their names in golden letters in history. These Empires and kingdoms have had many implications for regions. Especially in a region like Anatolia, the Osmanogullari principality, which rose from a principality to an empire, had many effects on these regions. The most important of these is to ensure the integrity of the religion of Islam. Before it came under the rule of the 9th Ottoman Sultan, Yavuz Sultan Selim, the Ottoman Empire, Anatolia and Rumelia had been opened, but he had no initiative or action regarding the Arabian peninsula, which was a member of his own religion and accepted as holy lands, and Egypt, which had an important place in historical literature. Yavuz's father, Sultan II. Because of Bayezid's peaceful policy and his diplomatic policies in state affairs rather than war, power could not be established in this region. The Ottomans thought of themselves as the heart of Islam and the only leading state to spread it. At the suggestion of Yavuz Sultan Selim, the Ottoman Army, which set out from Istanbul, marched on the Mamluks with the battle of Mercidabık after defeating the Safavid empire in the Battle of Çaldıran. The Mamluks suffered heavy losses and Yavuz continued his campaigns. Finally, he defeated the Mamluk state in the Battle of Ridaniye and ended the Abbasid caliphate. The effect of the Ottoman domination in these places ended the fighting and war in Islamic lands. The second effect was to initiate and accelerate the Renaissance reform revolutions in Europe. In those years, there was an oppressive religious administration in Europe. The Europeans, who supported this administration with the inquisition courts, tried the citizens, kings or nobles who acted against religion in these courts and prevented this. At that time, in Italy, there were fragmentary duchies and fiefdoms. People here were less affected by religious and bigoted practices in Europe and followed the developments that would pave the way for science. With the conquest of Istanbul by Mehmed the Conqueror, the 7th Ottoman Sultan, scientists and scholars in the Byzantine state were attracted to the fact that Italy was so comfortable and they went there. With the effect of this, acceleration in the Renaissance reform revolution took place. In the future, the European people, living in oppression and bigotry, would expel the Turks from Rumelia and even attempt to gain their independence. To summarize briefly, the Ottoman empire had many effects on world history. These are the acceleration of the Renaissance reform revolutions and the Islamic states conducting diplomacy without conflict and war within a certain period of time. As a matter of fact, Turks and all people should learn from these effects and get an idea, so that more comfortable development can be achieved in science, technology and the branches of science that have derivatives.
