This application contains the Ottoman History subject summaries. All stages from the establishment of Osmali to the first world war were summarized. By concentrating on the information that should be known by avoiding unnecessary detail, this application is prepared. The visuals have been increased with the paintings of the sultans. Knowing the saints and our history is the priority of those who live in this land. It is an application aiming to support students who are preparing for KPSS and LYS exams by considering this priority. It is also a practical educational application for students and teachers who take history courses in schools. If you report missed misses and mistakes, we have a chance to correct them. Thank you.
