The suggestion that teaching is a political act has been a divisive issue among educators. However, there has been little analysis of the ways that teachers draw on their political experiences as pedagogical resources. Using a case study of seven teachers in Porto Alegre, Brazil who were involved in politics, this article explores the relationship between political experiences and teaching citizenship. The data consisted of interviews with the teachers, observations of their teaching, and classroom materials. This research shows that politics played an important role in their efforts to teach democratic citizenship. Through the teachers' diverse political experiences and ideologies, they developed different understandings of the relationship of politics with citizenship education that promote democratization and social change.
