Guzmán believed that communism required a "popular war" and distanced himself from organizing workers. Beginning on 17 March 1980, the Shining Path held a series of clandestine meetings in Ayacucho, known as the Central Committee's second plenary. It formed a "Revolutionary Directorate" that was political and military in nature and ordered its militias to transfer to strategic areas in the provinces to start the "armed struggle". The group also held its "First Military School", where members were instructed in military tactics and the use of weapons. They also engaged in "Criticism and Self-criticism", a Maoist practice intended to purge bad habits and avoid the repetition of mistakes. During the existence of the First Military School, members of the Central Committee came under heavy criticism. Guzmán did not, and he emerged from the First Military School as the clear leader of the Shining Path.
