This article analyzes different figures of violence that regularly agitate the Supreme Rada, the Ukrainian Parliament (blocking of the tribune and the podium of the Chamber, deterioration of voting materials and microphones), are accompanied by acoustic and visual disturbances and occasionally end in scenes of physical violence. It shows that these figures of violence are used in instrumental way by parliamentary actors and appear to them as a possible mean of political competition. If parliamentary violence, generative of disorders, reveals the difficulties with putting the Ukrainian Chamber "into order", it contributes paradoxically to the process of parliamentary order institutionalization, which is "under way" here and elsewhere.
