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
In 1956, due to the territorial cut due to the expansion of the Constitutional Province of Callao, an area of conflict arose with the Callao District. This dispute arose from the imprecision in the wording of the boundaries and the lack of cartography of the law, in addition to the disappearance of the original stone milestones due to the urbanization process. The conflict or indetermination of limits is still in force, as it corresponds to a district-provincial struggle, and is waiting to be fully defined by the Metropolitan Municipality of Lima, the Regional Government of Callao, the Provincial Municipality of Callao, the Municipality of San Martín de Porres, the Presidency of the Council of Ministers and the Congress of the Republic.[5]
In 1989, 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.[6] 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 Independencia (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.[7]
