When the domestic justice system is unable to deal with the crimes of its political agents, international jurisdictions need to take action. The duty to curb crimes against humanity derives directly from international commitment. If Brazilian institutions fail to judge Bolsonaro for his crimes against indigenous peoples, we hope that the ICC and history will do so. The Articulation of Indigenous Peoples of Brazil (APIB) communicated to the Court and pointed out the dismantling of indigenous policies, the encouragement of invasions of indigenous lands, and the denial of fundamental actions for our survival. This contribution aims to share the reasons for going to the ICC. In the case of indigenous peoples it presents the acts committed by Bolsonaro and his subordinates from Jan 2019 to April 2021. We report how singular acts are systematically connected to destroy indigenous peoples in Brazil. That is why we speak of crimes against humanity. That's why we talk about genocide.
