Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period. The reason for this choice is that the topic is required according to the current curriculum Lgr11. The essay will show an investigation about a few selected textbook authors. The main question is if the authors write as the textbook tradition or according to the curriculum. Four different textbooks will be compared in this paper where two of these books have the same publisher, the same author but two different curriculums (Lpo94 and Lgr11). The essay is based on a qualitative research in which a text analysis is done – to analyze if the textbooks follows the required topics of the curriculum or following the textbook tradition. Even an quantitative study has been done as an analysis of textbooks whereas the amount of pages and headlines are in focus. This was made to compare how much the authors have written about the interwar period and if similar headlines was used. A comparison of different curriculums has also been done, between the Lpo94 and Lgr11. This was made to see if there was a change in content or how authors wrote about the same historical event. This may provide an explanation for why the textbook authors have written different in both textbooks written by the same author and printed by the same publisher but in line with two different curricula.
