The
ongoing rebellion of the
New People's Army began in 1969 under the auspices of the
Communist Party of the Philippines (CPP), which had been formed the previous year. This conflict was still in its infancy in 1972 when
Ferdinand Marcos proclaimed
Martial law, but expanded significantly as even the moderate opposition against Marcos was radicalized. The CPP went through a series of setbacks and internal conflicts after the ouster of Ferdinand Marcos in 1986, including the breaking away of the
Cordillera People's Liberation Army of former priest
Conrado Balweg. CPP co-founder
Jose Maria Sison went into exile in the
Netherlands in 1987 while
Benito Tiamzon reportedly became the leader of the party upon successively acquiring the positions of chairman and secretary general in 1986 and 1987 respectively. In 1992 the CPP went through what it calls the
Second Great Rectification Movement, whose stated intent was to "identify, repudiate and rectify the errors of
urban insurrectionism, premature big
formations of the
New People's Army and anti-
infiltration hysteria". This resulted in the split of the party into "Re-affirmist" and "Rejectionist" groups, resulting in the formation of at least 13 factions during the 1990s. == Cordillera People's Liberation Army conflict (February–September 1986) ==
