Abstract This article examines the use of hate speech and incitement by perpetrators of violence and atrocities in Myanmar against vulnerable populations like the Rohingya community from the outbreak of communal conflict in Rakhine in 2012 to the post-February 2021 coup. It argues that there is a clear link between hate speech and incitement, on one hand, and the escalation of violent attacks against the Rohingya and other ethnic minorities in the country, which presaged the atrocities committed by security forces. It draws some implications for R2P and atrocities prevention from the Myanmar case study, which includes the flawed democratisation process initiated by the military and the manifest failure of both the usdp and nld governments to uphold their primary responsibility to protect vulnerable populations in the country. As well, the international community led by the United Nations and asean have both failed in their responsibility to respond in a timely and decisive manner to protect the Rohingya from genocide as well as the larger civilian population from the junta’s violent crackdown after the February 2021 coup.
