This study examines the impact of post-truth discourse during the 2019 Sudanese Revolution and the subsequent transitional period, as well as the role played by social media platforms in promoting this discourse and mobilizing broad segments of the population behind it. The study also explores the susceptibility of social media users to follow false news in contrast to their engagement with factual reporting. It argues that the Sudanese Revolution and the transitional phase (2019–2023) coincided with the emergence of a new media landscape rooted in a politically and socially divided environment, characterized by diverse perspectives and the growing influence of social media. These platforms played positive roles in the dynamics of the revolution, significantly contributing to the mobilization of large popular groups to participate in demonstrations and sit-ins that ultimately led to the regime's overthrow. However, they also generated confusion and uncertainty among these groups due to the rise of post-truth discourse fueled by fake news, which in turn intensified polarization among revolutionary youth and activists.
