This essay is a textbook study where I aim to review four textbooks regarding some historical events in the subject History. The textbooks are used in junior high school and the historical events are as follows: the genocide that happened in Congo during the leadership of king Leopold II, the genocide on Armenians in the Ottoman Empire, the Holocaust and the Vietnam War. By performing this study I wanted to answer these three questions: What differences and similarities can be found in how the events circumscribed? How much space do the various events have and has it evolved through the years 1980-2009? How can this be explained? The study has been analyzed from a post-colonial perspective and the recurring patterns that appear show how the texts are post-colonial. This means that the authors of the textbooks are writing about the same subjects, but in very different ways.
