The political atmosphere of Bangkok, Thailand has been the center of much discussion in the international media. Thailand places the monarchy as an indispensable position in the lives of the people. Lèse-Majesté legal provisions are used by the ruling regime to control free speech. The widespread suppression of free speech online provides an opportunity to curb criticism of the opposition, but can also undermine the credibility of Thailand's authoritarian monarchy laws. This research aims to describe the movement against monarchy law in Thailand by the Future Forward Party (FFP). The conceptual foundation used is about social movements with descriptive qualitative research methods through literature studies of scientific literature. The results of the research explain that Future Forward Party (FFP) is a pro-democracy party that opposes the Lèse-Majesté law in Thailand. This party movement was then followed by students and the public in large demonstrations that had the aim of ending a government's power and limiting the power of a king. The growing number of teenagers joining the protests was the most prominent feature of the pro-democracy movement.
