The goal of this master's thesis is to analyze the representations of wars during the breakup of Yugoslavia in contemporary Croatian and Serbian high school textbooks. This paper is not concerned with the accuracy of the stated facts and instead focuses on dealing with the breakup of Yugoslavia as an example of a sensitive and controversial topic. For the purpose of this analysis, this paper explains the rules and methods for working with sensitive and controversial issues as well as most common mistakes. In addition, the paper also analyzes the representation of the conflicting parties and summarizes the textbook narrative, which requires explanations and introduction to imagology and discourse analysis. Historical context of history textbooks is also explained for the purpose of assessment whether Croatian and Serbian textbooks changed their approaches to this topic over time. The subjects of analysis are 4 Croatian and 2 Serbian textbooks, all of which were published after 2019. Croatian textbooks were published in 2021, and the Serbian textbooks were published in 2023. The analysis is divided into 4 topics: the war in Slovenia, the Homeland War or the war in Croatia, the war in Bosnia and Herzegovina and the war in Kosovo. The paper tries to answer the question of what strategies and criteria contemporary Croatian and Serbian high school history textbooks follow and what mistakes they make. It will also answer the questions how the textbooks portray the warring sides.
