New Mexicans became Americans in 1850. The Mexican American War lasted from 1846-1848. After the Mexican Republic formally ceded the region to the United States in 1848, a temporary wartime and military government persisted until September 9, 1850.
The Territory of New Mexico was first organized as an incorporated territory of the United States that existed from 1850 until 1912, when the remaining extent of the territory was admitted to the Union as the State of New Mexico, making it the longest-lived organized incorporated territory of the United States, lasting approximately 62 years.
For over 170 years now, New Mexico has been a part of the American community, united by the common values we share. On January 6th in 1912, New Mexico was admitted to the union of the United States as the 47th state, setting it on a historic path.
In so doing, we recognized our belief in a fundamental set of principles founded on liberty, freedom, and personal responsibility. We joined a society governed by the Constitution, a document that empowered the people instead of a king and wrote into law an unprecedented form of republican governance.
We are proud to announce the creation of the 1850 Society, an association aimed at honoring the time-tested principles that we share, which we can trace back to the very beginning of our becoming American. This membership society is brought together to honor and connect those donors who support the work of the Rio Grande Foundation at a certain annual level.
Through this exclusive giving club, members will get special updates from the president, a lapel pin and auto decal to showcase their membership, and advanced notice and reserved seating for events.
