This work intends to analyze the social representations of the history of Brazil by brazilian undergraduate students, using the theory of social representations by Serge Moscovici. A questionnaire was answered by 1029 students from seven states in the five geographic brazilian regions. The students were asked to localize and describe the most important historical facts of Brazil. The answers were structured as narratives about moments of the Brazilian history, emphasizing the arrival of the portuguese, the settling, the creation of Brasilia and permanences in which history fuses with culture and nature. The forgotten facts, a kind of affective wound in the memory, can be understood as selections plunged in affectivity, compose these social representations of history.
