PCP-SL achieves control of the Ene and Tambo river basin

In mid-1989, in the central jungle, the PCP-SL achieved absolute control of the Ene River basin and part of the Tambo River basin, thus gaining control of the entire province of Satipo (Junín). This territorial control was achieved at the cost of the razing of dozens of communities, the murder of natives and settlers, and the compulsive enlistment of hundreds of natives. The PCP-SL had begun to gain a greater presence in the central jungle, particularly in the Ene River basin, since the end of 1987. In 1991, the Ashaninka of the Ene and Tambo rivers organized themselves into Self-Defense Committees to confront the PCP-SL.
