ORDEN, or Organización Democrática Nacionalista (National Democratic Organization) was a Salvadoran paramilitary organization founded under the military rule of Julio Adalberto Rivera, headed by José Alberto Medrano. ORDEN helped control the 1972 elections, in which reform-minded José Napoleón Duarte lost to Arturo Armando Molina (of Rivera's party, the Party of National Conciliation (PCN)) due to fraud.
ORDEN was originally established in 1961 as a civil defense apparatus, composed of army reserve units and commandeered peasants. According to the Human Rights Institute of the Central American University, one of ORDEN's principal functions initially was to identify and eliminate purported communists among the rural population. Under Colonel Jose Alberto Medrano's command, ORDEN was transformed into a highly organized militia force, with military officers in command at the department level, non-commissioned officers coordinating actions from municipal centers, and many members drawn from army reservists and retired National Guard and Treasury Police officers. ORDEN functioned the intelligence-gathering instrument of the Salvadoran armed forces (FAES) while also acting in anti-insurgent operations and helping in military recruitment. Its structure was composed of senior military officers directly responsible to the president, and it functioned as the brain of a security network that spanned the entire country, providing information and coordinating the activities of death squads.
Invasión is an Argentine film released in 1969 and directed by Hugo Santiago. It is an example of an inter phase between the classic cinema and nouvelle vague of French style.
A group of men commanded by an older man attempts to stop an invasion to the city of Aquilea. The invaders are common men who defend the city, ignored by the people in general, but with the development of the film it is understood that the invasion is absolute and impossible to define. The defeat of the defenders is evident from the beginning, as in the "Trojan War".
