Was Nevada once Mexican territory?
YES
The land of present-day Nevada was briefly under Mexican control in the early 19th century.
Spain had laid claim to the territory 300 years prior. Native American tribes such as the Paiute, Washoe and Shoshone lived on the land for thousands of years before European contact.
Spain’s weakening geopolitical position inspired an outbreak of revolts throughout Spanish America. The conclusion of the Mexican War of Independence in 1821 transferred the territory to the newly established Mexican Empire.
But Mexican control was short-lived. After Mexico refused to sell lands to the U.S., the expansionist-minded president James K. Polk ordered construction of a military camp in Mexican territory in 1846, provoking an attack.
The Mexican-American war was fought over the next two years, ending in a U.S. victory. The resulting treaty required Mexico to sell more than half of its land — including Nevada — to the U.S., at about half of the original asking price.
