Report Potentially Offensive Description in Library Special Collections.
When the United States took possession of California and other Mexican lands in 1848, it was bound by the Treaty of Guadalupe
Hidalgo to honor the legitimate land claims of Mexican citizens residing in those captured territories. In order to investigate
and confirm titles in California, American officials acquired the provincial records of the Spanish and Mexican governments
in Monterey. Those records, most of which were transferred to the U. S. Surveyor General's Office in San Francisco, included
land deeds, sketch-maps (diseños), and various other documents. The Land Act of 1851 established a Board of Land Commissioners
to review these records and adjudicate claims, and charged the Surveyor General with surveying confirmed land grants.
Additionally, to determine the validity of Spanish and Mexican land grants in California, Congress set up a Board of Land
Commissioners. Unless grantees presented in two years evidence supporting their title, the property would automatically pass
into the public domain. Although the Land Commission eventually confirmed 604 of 813 claims, the cost of litigation forced
most Californios to lose their lands. Government attorneys appealed 417 claims, out of a total of 813. Some cases were appealed
several times; appeals prolonged each litigation process for an average of seventeen years. Questions of title were settled
by the Federal courts, and authority to segregate claims judicially confirmed was vested in the proper executive officers
of the United States.
The remainder of privately owned Mexican territory annexed to the United States was settled under the the eighth section of
the act of July 22, 1854, which made it the duty of the surveyor-general to ascertain the origin, nature, character, and extent
of all claims to lands under the laws, usages, and customs of Spain and Mexico and to report the conclusions to Congress.
The law did not impose a limitation of time in the presentation of claims or a penalty for failure to present. In the next
thirty years, more than one thousand claims had been filed with the surveyor-general, of which less than one hundred and fifty
had been reported to Congress, and of that number, Congress acted upon seventy-one. Under the law, only copies of the original
title papers were submitted to Congress. Of the 813 grants ultimately claimed, the land commission approved only 553.
Oversize folio of approximately 150 hand-drawn maps of Mexican land claims in California; each map depicts a tract of private
land, or ranch, with the major boundaries of the claim written in Spanish. Most maps are dated between 1841 and 1883, though
it is unclear if these dates represent the time of the maps' creation, or if they are merely transcriptions of dates from
an original, older source. Most of the maps are stamped with the seal of the Pacific Coast Abstract Bureau, dated 1891, which
suggests that they were used for some official or governmental use. Maps are in black ink, on heavy cream paper, with occasional
pencil notations or watercolor details. The drawings are not credited to individual copiers, surveyors, or artists, though
the English language notations were probably made by land claim officials. Includes an index listing the names of the properties
and corresponding page numbers.
