With the region’s population booming because of the Pike’s Peak gold rush, Congress creates the new Territory of Colorado.
When the United States acquired it after the Mexican War ended in 1848, the land that would one day become Colorado was nearly unpopulated by Anglo settlers. Ute, Arapaho, Cheyenne, and other Native Americans had occupied the land for centuries, but the Europeans who had made sporadic appearances there since the 17th century never stayed for long. It was not until 1851 that the first permanent non-Indian settlement was established, in the San Luis Valley.
As with many other western regions, though, the lure of gold launched the first major Anglo invasion. In July 1858, a band of prospectors working streambeds near modern-day Denver found tiny flecks of gold in their pans. Since the gold-bearing streams were located in the foothills not far from the massive mountain named for the explorer Zebulon Pike, the subsequent influx of hopeful miners was termed the Pike’s Peak gold rush. By the spring of 1859, an estimated 50,000 gold seekers had reached this latest of a long series of American El Dorados.
As the first gold-bearing streams to be discovered played out, prospectors moved westward into the rugged slopes of the Rocky Mountains in search of new finds. Wherever sizeable deposits were discovered, ramshackle mining camps like Central City, Nevadaville, and Black Hawk appeared, sometimes almost overnight. Meanwhile, out on the flat plains at the edge of the mountains, Denver became the central supply town for the miners.
Although few miners came to Colorado planning to stay long, they were eager to protect their property rights and gold dust. Far from the seats of eastern government, the miners and townspeople cobbled together their own simple governments, usually revolving around a miners’ court that regulated claims. Technically lacking in any genuine legal foundation, the miners’ courts did maintain the minimal order needed for the mineral exploitation of the territory to continue.
The unreliable mining operations soon gave way to larger, highly capitalized and relatively permanent lode mining operations. The pioneers recognized that the vast mineral resources of the Rockies could form the foundation of a thriving new state, but the people settling there needed a more formal system of laws and government. The Congressional designation of new western states and territories had been bogged down for several years as southern and northern politicians fought over whether slavery would be permitted in the new western regions. By 1861, the South had seceded, clearing the way for the northern politicians to begin creating free-labor states.
