Technology changed our world and shapes our reality in forms that widely differ from the traditional ones. Discourse and persuasion are not an exception. This study analyzes the tweets and oral discourses of eight politicians and social leaders during three of the most important days in the independence struggle between Catalonia and Spain to argue that the way people in power try to persuade their voters is changing, especially in new social networks such as Twitter.

The main object of study are the argumentative and persuasion processes that take place both in Twitter and oral discourses from the same politicians and the same day. That way the rhetorical methods used can be properly compared and put into context. In dialogue with other studies about Twitter or the new discourses in the social media, this study presents the New Argumentation of Twitter, which theorizes how politicians adapt their argumentative processes to the new formats and audiences that social networks such as Twitter provide.

La Nueva Argumentación de Twitter: el Cambio de Paradigma Retórico y la Independencia de Catalunya en Tuits brings new perspectives to the field of discourse analysis and, specifically, to argumentation studies. Using Critical Discourse Analysis as the main theoretical frame to analyze both the tweets and the oral discourse, this study goes further than the mere discourse and provides an overview of how the new rhetorical paradigm can affect political discourse and their understanding, shedding light onto how power behind discourse is also represented in the new forms of argumentation on Twitter.

In summary, throughout the analysis and comparison of more than twenty oral discourses and over two hundred tweets produced by eight political personalities during the Catalonia-Spain struggle in 2017 and 2019 this study introduces the new argumentative paradigm used by politicians in Twitter.

Finally, the results show that the ways in which politicians try to persuade in oral discourses and on Twitter are changing and therefore we, as political, social and democratic actors, need to be aware of that. By being able of understanding how we are being persuaded one will become more politically empowered and free, which should result in a better democratic quality.
