Documents, bound together in a leather portfolio, produced by Spanish public notaries during the 17th century relating to property titles of lands in the region of Itzmiquilpa near Mexico City. The notarial documents in this collection can be divided into two categories: "escribanias de merced" and "cartas de venta." The "escribanias de merced" or "mercedes" relate to feudal customs in the occupation of land in the Spanish Empire. The "merced" was a feudal title bestowed on a colonial aristocrat by the viceroy giving the beneficiary economical and judicial rights over a specific territory. The "cartas de venta" or "titulos de venta" refer to the sale of the feudal rights acquired with the property of a "merced." According to Pablo Macedo's 1908 letter, this collection includes notarial documents signed by three of Mexico's viceroys: the marqués de Salinas, Don Luis de Velasco, dated 1609; the marqués de Guadalcázar, Don Diego Fernandez de Córdova, dated 1614; and the conde de Monterrey, Don Gaspar de Zúñega y Acevedo, dated 1601.
