The protests were sparked by the Colectiv nightclub fire, and were dubbed in the Romanian press as the #Colectiv Revolution. The protesters demanded the resignations of Prime Minister Victor Ponta and Minister Gabriel Oprea, who they claimed fostered corruption which led to the disaster. They also called for the resignation of Cristian Popescu Piedone, the Mayor of Sector 4, who was criticized for giving an operating license to the club without a permit from the fire department.
