The chapter presents the discussion on intertextuality role in political discourse, namely in key leaders' political speeches. Intertextuality highlights the uncontested dialogicity of political discourse and takes it to the next level of decoding the speaker's message to the audience. By means of intertextuality, political leaders establish links with their audience outlining common values with the support of history, cultural traditions, and religion. Research into the speeches by key politicians allows the authors to reveal trends of intertext usage in European and American political discourse.
