The aim of this study is to examine to what extent and how the history of mathematics is used within the content of mathematics textbooks which that had been used by The Ministry of National Education in 2019-2020 academic yearyear. Therefore, in the study, which preparation principles and distribution methods have been used wereare mentioned. Then, sixteen secondary school mathematics textbooks recommended by the Ministry of National Education for the relevant academic year were examined by using the document analysis method, one of the qualitative research approaches, as a research method. Moreover, how textbooks are determined and which distribution methods are used in some European countries has been examined. Ulteriorly, by using document analysis method which is one of the qualitative research approaches, sixteen secondary education mathematics textbooks which had been suggested by The Ministry of National Education for the mentioned academic year have been analyzed. The informations about mathematics history information in the textbooks havewas been examined through the determined questions and the quantitative datas within the scope of the within the results have been presented with by graphics and tables. It is thought that the findings obtained in the research will contribute to the preparation and development of secondary school mathematics textbooks.
