This article investigates the catalysts behind the significant social mobilization against Myanmar’s military regime following the February 2021 coup. In response to the coup, the Burmese populace organized widespread peaceful protests and civil disobedience campaigns, united by their collective pursuit of restoring democracy. Leveraging data from the 2019 Asian Barometer Survey and the Armed Conflict Location and Event Data (ACLED), we examine previous instances of social mobilization against the military regime. Applying Charles Tilly’s mobilization theory, we explore how the WUNC (Worthiness, Unity, Numbers, and Commitment) theory sheds light on the social mobilization of the Burmese people, with a particular focus on the pattern of peace demonstrations. Our findings reveal a crucial link between pre-coup commitment and subsequent peaceful street demonstrations. Utilizing quantitative methods, we analyze the relationship between WUNC elements and the likelihood of individuals participating in social mobilization and actual street demonstrations following Myanmar’s military coup. Our findings underscore the importance of social capital and liberal democratic values in motivating individuals to support democratic governance, even under Myanmar’s challenging conditions. In conclusion, we argue that by strengthening social capital and promoting liberal democratic values, the people of Myanmar may be more inclined to engage in peaceful street demonstrations to resist authoritarian rule. Our research contributes to understanding factors that fuel social movements against oppressive regimes, enriching the literature on social mobilization in Myanmar.
