The Democratic Societies Melo returned to Colombia in 1841, after an amnesty offered by President
José Ignacio de Márquez during the
War of the Supremes. Despite his military training in Germany, he did not rejoin the army and instead settled in Ibagué, where he engaged in several commercial ventures and even taught classes at the . He eventually became a regional political leader. The artisans also demanded
tariffs on imports from industrialized countries like England and the United States, which they argued were detrimental to the development of national industry. They rejected the
Mallarino–Bidlack Treaty signed by the administration of
Tomás Cipriano de Mosquera, which allowed the U.S. to intervene in Panama, which at the time was a
Colombian province, to protect their economic interests. In June 1849, President López appointed Melo, who had rejoined the military in 1847, the commander of the Hussars Cavalry Corps, garrisoned in Bogotá. In this capacity, Melo fought against the
insurrection of 1851, where slaveowners and conservatives led by
Julio Arboleda Pombo took arms against the López government in protest of the abolition of slavery. He was promoted to the rank of general, and managed to raise a militia of 3,000 volunteers to suppress the rebellion in
Cundinamarca, which was being led by
Mariano Ospina Rodríguez. Melo managed to defeat the rebels at
Guasca, and after the rebellion was suppressed in the rest of the country, was named commander of military forces in Cundinamarca in June 1852. In August 1850, the artisans demanded protection and the creation of a national workshop supported by the government. Melo founded a newspaper,
El Orden, in 1852. Though its intended readers were military officers (and it railed against the Golgothas' proposals to reduce garrisons in urban centers), it became closely associated with both the Draconian Liberals and the artisans of the Democratic Societies. The publication attacked both the Conservatives and the Golgothas, accusing them of planning to sell Panama to the United States, and of scheming to exile prominent Draconians like
José María Obando. Despite the constitution's progressive nature, Obando and the Draconians were not entirely satisfied, aware that the document had been drafted by the Golgothas.
Quiroz affair In 1853 and 1854, Liberal Bogotá became fractured between the artisans and the merchant class, especially after a tariff bill failed in the Golgotha-controlled Colombian Senate. The city was facing a severe food shortage, exacerbated by the tax law of 1853. Violent street battles occurred between the two groups, and a coup d'etat against Obando was discussed as a real possibility. This was the backdrop for the Quiroz affair in March 1854, where various political enemies of Melo accused the general of being responsible for the death of a corporal under his command, Pedro Ramón Quiroz, who was fatally wounded in a street brawl in January. Melo was said to have struck the corporal with his sword after he resisted arrest. In court, Melo produced evidence proving he was at regimental headquarters at the time, and also the deathbed testimony of Quiroz himself, to exonerate himself. However, both the case's judge, , and the Mayor of Bogota, Lorenzo González, were political opponents of Melo and sought to discredit this testimony. As the trial went on in April 1854, the situation in Bogotá continued to deteriorate. Golgothas fought with Draconians in the streets, and armed artisans rallied to the slogan
pan, trabajo, o muerte (bread and work, or death). Vice President Obaldía, himself a Golgotha, recommended to President Obando that Melo be discharged from the Army immediately in the name of preventing an insurrection, though Obando declined. == Eight-month presidency ==
