As Orhan Ghazi is saying, the same thing happened in history, the Ottoman Empire was only gaining victories towards Europe and the infidels, it never paid attention to Anatolia. While fighting with the infidels, the rest of the chieftains were always fighting among themselves and conquering each other’s states. After that, the Ottoman Empire looked back and after 100 years, within 100 years, it started conquering all the states of Anatolia because of the infidels. After fighting, only this state became powerful and then the Seljuk land, Garmian, Kerman, Egypt, Africa, Saudi Arabia, Mamluk, all the states were conquered by the Ottoman state.
