In 1987, the PCP-SL began its violent activities in the Tulumayo basin, which includes the districts of Comas, Cochas and Mariscal Castilla in the province of Concepción. The key date was September 12, 1987, when a Shining Path column successively raided the capitals of Comas and Cochas, threatening authorities and demanding resignations. The communities of Upper and Lower Tulumayo were convulsed by the action of the PCP-SL columns. At the end of 1987, the MRTA also sporadically entered some communities and towns in Tulumayo. The PCP-SL combined armed actions and assassinations with political organizing work, installing Popular Committees in many communities after the withdrawal of police posts.
