Alexei Navalny, a Russian journalist, and an anti-corruption activist released an almost 2-hour-long documentary of his investigations regarding the corruption Vladimir Putin, the President of Russia had done. This research aims to find the Anti-corruption discourse within that documentary, named "Putin's Palace. History of World's Largest Bribe". The documentary has reached over 120 million views, and the message communicated by Alexei Navalny seems to be effective. This thesis intends to research and prove the discourse of anti-corruption within the documentary and whether the ideology of Navalny had been conveyed through Critical Discourse Analysis by Norman Fairclough. Furthermore, two theories used to develop this thesis, Language and Power and Media and Politics, support the research’s findings and analysis. There are several anti-corruption discourses in the documentary from chosen dialogues and the messages are transmitted to a global audience, with Alexei Navalny urging the viewers to share the video and for locals to protest. Alexei Navalny has been demonizing Vladimir Putin’s public image throughout the whole video while including images and videos to make his investigation believable. Another outcome of the research is how Alexei Navalny has been utilizing the ideology of anti-corruption to promote another agenda, Anti-Putin. The writer expects that this research may bring contributions to the development of socio-political science, particularly in the anti-corruption aspect and Critical Discourse Analysis.
