The majority of the state of New Mexico was obtained by the U.S. at the end of the Mexican War. The rest of the state was acquired in 1853 as part of the Gadsden Purchase. The state isn’t named after Mexico (named by Spanish explorers in 1581 after the Mexica, a group of Aztec peoples). The Apache Wars (conflict between the U.S. Army and various Apache nations) ended in 1886. Until then, the state of New Mexico was involved in many conflicts.
Modern-day New Mexico leads research and development in alternative energy sources. The Los Alamos Scientific Laboratory is the center of this innovation, focusing on solar, geothermal, and nuclear power. Land in the state is relatively cheap and is therefore attractive to small business entrepreneurs without a lot of investment capital.
