San Martín de Porres (SMP) is a district in Lima, Peru, located in the north area of the city. It is bordered by the Chillón River, marks its natural border with Ventanilla and Puente Piedra on the north; Callao on the west; Los Olivos, Comas (disputed areas) on the northeast; Rímac and Independencia districts on the east; The Rímac River marks its natural border with Lima District and Carmen de la Legua Reynoso on the south. History Since 1945, continuous invasions of territory in what was then part of the Carabayllo District, ended up in the creation of the Distrito Obrero Industrial 27 de Octubre on May 22, 1950, which is still celebrated as the district's anniversary. The district was composed of the following haciendas: Chuquitanta, Pro, Naranjal, Infantas, Santa Rosa, Garagay Alto, G. Bajo, Chavarría, Mulería, Aliaga, Condevilla, San José, Palao, Huerta Sol, Oquendo, San Agustín and Marquez. The last three became part of Callao province, in 1956. In 1962, after the canonization of St. Martin de Porras, the name of the district was changed to its current name. Although historians have shown that the saint's actual last name was Porras, the district has retained the original spelling. The district of Los Olivos was created in 1989, stripping some of San Martín de Porres' northeastern territory. Borderline conflicts Due to the territorial reduction due to the creation of the Los Olivos district, two conflict zones arise, one with the Independencia district and the other with the Comas district. These districts argue that, when Los Olivos was created, part of the old industrial zone in San Martín de Porres would correspond to them to be annexed, however, according to San Martín de Porres, the law for the creation of a new district could not detail the transfer of territory to others not involved and because it was not an express request of the residents. It also highlights that the laws creating Comas (Law No. 13757) and Independence (Law No. 14965, Law No. 16012) mark their limits on the Old Pan-American North (today Avenida Túpac Amaru).The conflict remains and both zones are not yet defined by the Metropolitan Planning Institute, the Metropolitan Municipality of Lima or the Congress of the Republic. Conflict with Independencia district The first zone in territorial conflict is with the district of Independencia, in a quadrangular shape of 2.40 square kilometers. It is delimited by Av. Panamericana
