Initial settlement Compared to other cities and municipalities in Antioquia, San Luis has a relatively short history. Migration to the region began in 1875 and continued throughout the late 19th century, driven by economic hardship in the region and a spirit of entrepreneurship and colonial expansion that was dominant during that time. The founder of San Luis is widely considered to be Clemente Giraldo, a Presbyterian priest who sought to create a trading outpost between the cities of Granada and the Río Magdalena. Upon arriving in the region from Granada with several families, Giraldo reached a large stone cliff, named "el Castellón" in Spanish, on August 25, 1876, ow considered the official founding date of the municipality. Having found a defensible site in the mountains with plenty of forestry and available wood, Giraldo decided that this would be a very suitable site for the outpost. The settlers tested the fertility of the soil by planting banana trees, beans, sugar cane, and yuca and, after a successful harvest, returned to Granada to deliver news regarding the new settlement. Once news of the successful settlement spread, additional settlers arrived from the nearby towns of El Peñol, Marinilla, and El Santuario. By 1878, the town had constructed its first church, a central park and was integrated as a segment of the municipality of San Carlos. Effects of the Colombian conflict Since the 1960s, San Luis suffered a great deal during the Colombian Conflict, especially between 1994 and 2004. The city was frequently targeted by various terrorist and paramilitary organizations, including the FARC, ELN, and Frente IX and was subject to kidnappings, murders, and forced displacements. In 1997 alone there were 255 disappearances, 75 murders, 305 kidnappings and 51,513 displaced persons. By 1999, San Luis was an active war zone and many families fled to other parts of the country.
