March 10, 1848:
While February 2nd is noted by some as the original birthday of the first Chicanos, March 10th is notable too. because the version of the Treaty of Guadalupe Hidalgo ratified by the Senate was different than the one signed in Mexico a few weeks earlier.
Via the Library of Congress:
Other provisions stipulated the Texas border at the Rio Grande (Article V), protection for the property and civil rights of Mexican nationals living within the new border (Articles VIII and IX), U.S. promise to police its side of the border (Article XI), and compulsory arbitration of future disputes between the two countries (Article XXI). When the U.S. Senate ratified the treaty in March, it reduced Article IX and deleted Article X guaranteeing the protection of Mexican land grants. Following the Senate’s ratification of the treaty, U.S. troops left Mexico City.
This would be a significant part of the Chicano Movement in the 60s and 70s as people like Reies Tijerina fought to have the original land grants recognized.
As mentioned above, the civil rights of the new Chicanos were also amended from the version signed on February 2nd.
Article VIII guaranteed that Mexicans who remained more than one year in the ceded lands would automatically become full-fledged American citizens (or they could declare their intention of remaining Mexican citizens); however, the Senate modified Article IX, changing the first paragraph and excluding the last two. Among the changes was that Mexican citizens would “be admitted at the proper time (to be judged of by the Congress of the United States)” instead of “admitted as soon as possible”, as negotiated between Trist and the Mexican delegation.
The Treaty of Guadalupe Hidalgo is still relevant today, especially as states like Arizona pass law after law targeting our community. As Dr. Cintli Rodriguez discusses, the provisions guarding the civil rights of Mexicans in the ceded territories may be useful for those who seek to challenge SB 1070 and proposed laws affecting citizenship rights for children of undocumented immigrants.
