Most linguistic studies of political speaking in the field of critical discourse analysis tend to focus on speeches delivered by prominent politicians either in a domestic party-political setting or in the international arena. Less attention has been afforded to speeches by civil rights activists and campaigners for other progressive causes. To fill this gap, the present paper focuses on political speaking occurring outside of the party-political setting. The data comprises 120 American activist speeches from the years 1808-2016. The analysis focuses on the construction of ingroups and outgroups, and whether the use of personal pronouns is affected by the type of audience. The frequency trends bring forth new information about the referential complexity of pronouns within individual speeches.
