The Political Constitution of Colombia of 1991 (), is the Constitution of the Republic of Colombia. It was promulgated in Constitutional Gazette number 114 on Thursday, July 4, 1991, and is also known as the Constitution of Human Rights. It replaced the Political Constitution of 1886 and was issued during the presidency of the liberal César Gaviria, with ideas from the also liberal Luis Carlos Galán. History In the late 1980s, Colombia was facing a period of unprecedented violence. Although political violence had been commonplace in the country's history since the 19th century, and Colombia had been embroiled in an armed conflict primarily against guerrilla groups since the 1960s, in the 1980s the list of actors involved in the armed conflict became increasingly complex and the violence took on new forms. The conflict now involved new guerrilla movements, paramilitary groups and violent drug cartels (most famously the Medellín Cartel of Pablo Escobar). Politically, the National Front arrangement (1958–1974) between Colombia's two dominant parties, the Conservatives and the Liberals was widely seen as delegitimizing the political system by severely limiting third parties and other movements' political participation. Although the strict application of the National Front ended with the 1974 election, the power-sharing aspects of the system were dismantled only gradually - only in 1986 did President Virgilio Barco form a single-party Liberal government, after the Conservatives had rejected his offer of three ministries in his administration. A series of assassinations and terrorist attacks in 1988 and 1989 increased popular demands for political and constitutional reform, as the country's existing political institutions were seen as broken in the face of the wave of extreme violence. 1989 witnessed the assassination of 12 judicial officers, the assassination of Liberal presidential candidate Luis Carlos Galán on August 18 in Soacha, the bombing of the El Espectador newspaper's offices in Bogotá on September 2, the in-flight explosion of Avianca Flight 203 on November 27 and the bombing of the DAS headquarters on December 6 causing the death of 70 people. In 1990, two other presidential candidates were assassinated - Bernardo Jaramillo of the Patriotic Union (UP) was killed March 22, 1990, and Carlos Pizarro of the AD M-19 was shot on April 26, 1990. The August 1989 assassination of Luis Carlos Galán, who was the early favourite to win the 1990 elections, shocked public opinion in Colombia and led, seven days later, to a 'silent march'
