The Alianza Democrática M19 was a political party in Colombia, formed in 1990 from the demobilized guerrilla group known as the M-19. The M-19 was active from the late 1970s until the late 1980s, advocating for social justice and political reform. The party aimed to transition from armed struggle to political participation, seeking to address issues like inequality and violence in Colombia. The Alianza Democrática M19 participated in the 1991 constitutional assembly, contributing to the creation of a new constitution that aimed to enhance democracy in the country. The party gained significant support in the early 1990s but eventually lost influence and dissolved in 1997, marking a shift in Colombia's political landscape.
