History Ocosingo was given city status on 31 July 1979. Ocosingo rose to national prominence during the Zapatista uprising of 1994. It was occupied by the EZLN along with several other towns in Chiapas (including San Cristóbal). The EZLN retreated from most towns before the arrival of the Mexican army but not so in Ocosingo. Thus, the town saw several days of intense fighting, leaving dozens of rebels, soldiers and civilians dead. The body of a recently graduated doctor, Mariana Sánchez Dávalos, 24, was found in Nueva Palestina, Ocosingo, on January 29, 2021. Two months earlier she had denounced a sexual attack that had not been followed up by the state prosecutor (FGE). The lack of civil authority in the area made her job "high risk". Her death was classified a suicide, despite evidence of violence and the fact that she had been choked. Doctors and medical students throughout the state demanded an investigation, and #JusticiaparaMariana went viral on
