"The 19th of April Movement (in Spanish: Movimiento 19 de Abril) or M-19, was a Colombian guerrilla movement. After its demobilization it became a political party, the M-19 Democratic Alliance (Alianza Democr\u00E1tica M-19), or AD/M-19. The M-19 traced its origins to the allegedly fraudulent presidential elections of 19 April 1970. In those elections, the National Popular Alliance (ANAPO) of former military dictator Gustavo Rojas Pinilla was denied an electoral victory. The ideology of the M-19 was a mixture of nationalistic revolutionary socialism and populism. It was inspired by other South American urban guerrilla groups, such as the Tupamaros in Uruguay and the Montoneros in Argentina. By mid-1985, when the number of active members was estimated at between 1,500 and 2,000 (including a more noticeable urban presence), the M-19 was the second largest guerrilla group in Colombia after the Revolutionary Armed Forces of Colombia. It had become known for carrying out a number of awe-inspiring actions that provoked conflicting feelings of amazement and anger among the different sectors of Colombian public opinion."@en . . .
