The Revolutionary Bolivarian Movement-200 (Movimiento Bolivariano Revolucionario 200 or MBR-200) was the political and social movement that former Venezuelan president Hugo Chávez founded in 1982. It eventually planned and executed the February 4, 1992 attempted coup. The movement later evolved into the Movement for the Fifth Republic (MVR), set up in July 1997 to support Hugo Chávez's candidacy in the Venezuelan presidential election, 1998. The move to electoral politics took several years of intense internal debate, as many felt that the elections might be fixed to prevent an MBR-200 candidate winning. It took a nationwide survey conducted by the movement to show that it might gain enough electoral support to make victory hard to deny.
The movement's first members were Chávez and his fellow military officers Felipe Acosta Carles and Jesús Urdaneta Hernández. On 17 December 1982, as Chávez biographer Richard Gott reports, the three
Gott further explains that the suffix "200" was added to the group's name the following year, in 1983, on the 200th anniversary of South American liberator Simon Bolívar's birth.
The Beriev MBR-2 was a Soviet multi-purpose (including reconnaissance) flying boat which entered service with the Soviet Navy in 1935. It set several world records. Out of 1365 built, 9 were used by foreign countries including Finland and North Korea. In Soviet Union it sometimes carried the nickname of "Kорова" (cow).
The MBR-2 was designed by Georgy Mikhailovich Beriev and first flew in 1931, powered by an imported 373 kW (500 hp) BMW VI.Z engine. Production models, which arrived in 1934, used a licence-built version of this engine, the Mikulin M-17 of 508 kW (680 hp), and could be fitted with a fixed wheel or ski undercarriage.
Beriev also designed a commercial airliner derivation, the MP-1, which entered airline service in 1934, and a freighter version, which followed in 1936.
In 1935, an improved version was developed, the MBR-2bis, powered by the Mikulin AM-34N engine, and fitted with an enclosed cockpit, dorsal gun-turret and enlarged vertical tail. In this configuration, the machine remained in production until 1941. As with the MBR-2, the bis spawned a commercial derivative and the MP-1bis entered service in 1937.
