MR8

The Revolutionary Movement 8th October (MR8) (in Portuguese: Movimento Revolucionário 8 de Outubro) was formerly a Brazilian urban guerrilla group.

During the military dictatorship in Brazil, MR8 was formed by Brazilian Communist Party members who disagreed with the party's decision not to take part in armed resistance against the military government, the so-called Dissidência da Guanabara (DI-GB). The name Movimento Revolucionário 8 de Outubro was taken from another organization, recently destroyed by police repression. Dictatorship propaganda boasted of police effectiveness in suppressing of "terrorists," so the DI-GB began using the same name to demoralize the regime. The new organization defined itself as Marxist-Leninist and was the main force behind the kidnapping of American ambassador Charles Burke Elbrick in 1969, which was later the basis for the film Four Days in September.

In the late 1970s, MR8 conducted thorough autocriticism for its participation in armed resistance against the dictatorship. Under the leadership of Daniel Terra, it defined the struggle for "democratic liberties" as the primary task for the Brazilian left and became active inside the MDB, the party of the "allowed opposition," under Orestes Quércia, and had an important role in the reawakening of the student movement in 1976-1977.

However, It came to believe that the "national issue" was more important than the "democratic issue" and in 1978 shifted its policies. It never abandoned the struggle against the dictatorship, but became increasingly aggressive against other leftist movements, particularly the Trotskyists, frequently seen as antinational and supportive of "petty-bourgeois issues" like feminism, environmentalism, and gay rights. The MR-8 became increasingly isolated within the left, prompting alliances among other leftist movements against it.
