Today, when we look at the cultural scene in New Mexico, we can see direct evidence of Spanish occupation. The language of half the people in the state is Spanish, in some areas still the Spanish of the sixteenth century. Roman Catholicism, of which the Spanish were the most Catholic, dominates the religious scene. The Spanish heritage in political attitudes, in building and architecture, and in the legal tradition of the state is apparent. New Mexico, of all the states in the United States, is the only one that can claim a truly Spanish heritage. ANGLO-AMERICAN VIGOR While Spain lost its empire and New Mexico and the Southwest sank into poverty and decay, yet another force was on the march, a force that welled up in an Anglo-American people clinging to the Atlantic Coast of North America. As these people developed a nation, they also discovered a sense of destiny which turned their faces to the west and their footsteps toward the sunset. With them moved their culture. At first, it was a trickle, a few traders bent on profit, crossing the plains on the Santa Fe Trail. Then the trickle became a flood. For New Mexico, these men came as saviors. The Missouri traders broke the Chihuahua monopoly and goods from all parts of the world began to flow into New Mexico, resulting in higher standards of living. These Yankee traders, sensing a good thing, also penetrated the markets of Mexico, using New Mexico’s Royal Road to gain entrance. Again there was conflict, not Spanish and Indian, but Latin and Anglo-American. Mexico owned the lands of the Southwest and intended to keep them. But this American, with his gaze glued on western skies, refused to turn aside, and he strode on, grinding the feeble efforts of Mexican resistance into the desert sands. The Mexican War in 1846, suddenly transferred ownership of Texas, New Mexico, Utah, Nevada, Arizona, and California from Mexico to the United States. This was nearly half the territory of Mexico. New Mexico, with her already complex cultural pattern, was subjected to still another influence. The history of the American occupation of the Southwest is as complex and diverse as its predecessors. Its ingredients include cattle, mining, railroads, agriculture, science, and the Indian. All these, and others, combined to give an Anglo-American slant to the Southwest. The Indian culture did not disappear, nor did the Spanish, but rather a new stratum was cast that was to complete the mosaic. When the American arrived in New Mexico, he found a poor, backward area, hungry for trade and outside contacts. He found the Indians of the Southwest in open rebellion against the white men. The Navajo and other Apache groups, the Comanche, and some of the Pueblos were the primary offenders. This was to be the main problem occupying the time and energy of the American settler and soldier for forty years after 1846. Until the Indian situation was stabilized, there would be little economic and social development.
