The main purpose of this article is to present the results of a research project on the political participation of Latin American migrants in Andalusia (mainly in the cities of Seville and Huelva). The project uses a broad concept of what political participation constitutes, including both civic practices and activities associated with conventional politics, and adopts a transnational perspective. It is based on 45 semi-structured interviews with politically active migrants and members of politi- cal parties and other institutions. The article highlights some of the main findings of the research, including the importance of taking into account migrants previ- ous political experiences, as well as the role played by migrant associations in order to better understand their political practices.
