What drives Las Vegas’ History grade
On its age, its old homes and the National Register, Las Vegas is more historic than 95% of U.S. towns, #1 of 73 in New Mexico. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.
A
HistoryA character grade: shown, never part of Las Vegas’ overall grade.

Kearny delivered an address at the Plaza of Las Vegas claiming New Mexico for the United States. In 1847, the town was the site of the Battle of Las Vegas, which was a part of the broader Taos Revolt by local Hispanos and Pueblo peoples against United States occupation.

In the way of railroad talk it is expected that the St. Louis and San Francisco railroad, now at Vinita, Indian Territory, will ere long be pushed on to this place. Koads from Las Vegas to Galveston via Pecos Valley, and to San Juan country, in. Utah, via Mora and Toas, are being agitated. The Kansas^ Pacific, and Denver and Kio Grande, may at some near future day extend this way, and Las Vegas will always be an important point on the Atchison, Topeka and Santa Fe.
