Denver

Denver (/ˈdɛnvər/ ^ⓘ DEN-vər) is the capital and most populous city of the U.S. state of Colorado. Officially a consolidated city and county, it is located in the South Platte River valley on the western edge of the High Plains, and is just east of the Front Range of the Rocky Mountains. Denver is the 19th-most populous city in the United States and the fifth-most populous state capital, with a population of 715,522 at the 2020 census. The Denver metropolitan area, with over 3.05 million residents, is the 19th-largest metropolitan area in the country and functions as the economic and cultural center of the broader Front Range Urban Corridor.

Denver's downtown district lies about 12 miles (19 kilometers) east of the foothills of the Rocky Mountains. Named after James W. Denver, the governor of the Kansas Territory at the time, Denver was founded at the confluence of Cherry Creek and the South Platte River in 1858 during the Gold Rush era. Nicknamed the "Mile High City" because its official elevation is exactly one mile (5280 feet or 1609.344 meters) above sea level, Denver grew beyond its prospecting origins to become the principal commercial and transportation hub for a broad region spanning the Great Plains and Rocky Mountain West. The 105th meridian west of Greenwich, the longitudinal reference for the Mountain Time Zone, passes directly through Denver Union Station.

As the most populous metropolitan area in a 560-mile (900 km) radius, Denver is a major cultural hub with a variety of museums and cultural institutions, including the Denver Performing Arts Complex and Denver Art Museum. Denver has professional sports teams in five leagues and hosts the headquarters of eight Fortune 500 firms.

The greater Denver area was inhabited by several Indigenous peoples such as Apaches, Utes, Cheyennes, Comanches, and Arapahoes. By the terms of the 1851 Treaty of Fort Laramie between the United States and various tribes including the Cheyenne and Arapaho, the United States unilaterally defined and recognized Cheyenne and Arapaho territory as ranging from the North Platte River in present-day Wyoming and Nebraska southward to the Arkansas River in present-day Colorado and Kansas. This definition specifically encompasses the land of modern Metropolitan Denver. But the discovery in November 1858 of gold in the Rocky Mountains in Colorado (then part of the western Kansas Territory) brought on a gold rush and a consequent flood of white immigration across Cheyenne and Arapaho lands. Colorado territorial officials pressured federal authorities to redefine and reduce the extent of Indian treaty lands.

In the summer of 1858, during the Pike's Peak Gold Rush, a group of gold prospectors from Lawrence, Kansas, established Montana City as a mining town on the banks of the South Platte River in what was then western Kansas Territory, on traditional lands of Cheyenne and Arapaho. This was the first historical settlement in what later became the city of Denver. But the site faded quickly, and by the summer of 1859 it was abandoned in favor of Auraria (named after the gold-mining town of Auraria, Georgia) and St. Charles City.

On November 22, 1858,^{[contradictory]} General William Larimer and Captain Jonathan Cox, both land speculators from eastern Kansas Territory, placed cottonwood logs to stake a claim on the bluff overlooking the confluence of the South Platte River and Cherry Creek, across the creek from the existing mining settlement of Auraria, and on the site of the existing townsite of St. Charles. Larimer named the townsite Denver City to curry favor with Kansas Territorial Governor James W. Denver. Larimer hoped the town's name would help it be selected as the county seat of Arapahoe County, but unbeknownst to him, Governor Denver had already resigned from office. The location was accessible to existing trails and was across the South Platte River from the site of seasonal encampments of the Cheyenne and Arapaho. The site of these first towns is now occupied by Confluence Park near downtown Denver. Edward W. Wynkoop came to Colorado in 1859 and became one of the city's founders. Wynkoop Street in Denver is named after him.

Larimer, along with associates in the St. Charles City Land Company, sold parcels in the town to merchants and miners, with the intention of creating a major city that would cater to new immigrants. Denver City was a frontier town, with an economy based on servicing local miners with gambling, saloons, livestock, and goods trading. In the early years, land parcels were often traded for grubstakes or gambled away by miners in Auraria. In May 1859, Denver City residents donated 53 lots to the Leavenworth & Pike's Peak Express in order to secure the region's first overland wagon route. Offering daily service for "passengers, mail, freight, and gold", the Express reached Denver on a trail that trimmed westward travel time from twelve days to six. The Denver City, Kansas Territory, post office opened on February 11, 1860

On February 18, 1861, six chiefs of the Southern Cheyenne and four of the Arapaho signed the Treaty of Fort Wise with the United States at Bent's New Fort at Big Timbers near what is now Lamar, Colorado. They ceded more than 90 percent of the lands designated for them by the Fort Laramie Treaty, including the area of modern Denver. Some Cheyennes opposed to the treaty, saying that it had been signed by a small minority of the chiefs without the consent or approval of the rest of the tribe, that the signatories had not understood what they signed, and that they had been bribed to sign by a large distribution of gifts. The territorial government of Colorado, however, claimed the treaty was a "solemn obligation" and considered that those Indians who refused to abide by it were hostile and planning a war.
