The data of the research consisted of the Ministry of National Education (MNE) primary school 4th grade and secondary school 5th, 6th, and 7th grade social studies textbooks in 2021. The relevant textbooks were examined by focusing on the criteria prepared in line with expert opinions. As a result of the research, the following findings were reached: In the course texts, mostly due to the logical errors in the use of place names, anachronistic errors occurred. In the fictional texts, the views of the course book author are included as if they were the discourses of historical characters. Course book authors do not pay attention to time and space; they interpret the past with contemporary perspective, which causes anachronistic errors. There was no finding that could cause anachronistic errors in the "photographs and pictures" in the textbooks; however, it has been concluded that there are anachronistic errors due to the careless use of place names in historical maps.
