The territory was organized in the wake of the Pike's Peak Gold Rush of 1858–1862, which brought the first large concentration of white settlement to the region. The organic legislative act creating the slave-free Territory of Colorado was passed by the United States Congress and signed by 15th President James Buchanan (1791-1868, served 1857-1861), into law on February 28, 1861. During that period which at the same time (since beginning with South Carolina the previous December 1860), the secession of seven, later eleven southern slave states had been occurring those several months proclaiming / forming a new independent Southern government of the Confederate States of America (which eventually grew in the next year by two more divided state governments to thirteen in the Confederacy, with two alleged western territories) that precipitated the American Civil War of April 1861 to June 1865. The boundaries of the Federals' newly designated Colorado Territory were essentially identical with those of the current / modern State of Colorado, with lands taken from the four surrounding previous Federal territories of Nebraska, Kansas, New Mexico, and Utah (Deseret) established during the 1850s. The organization of the new territory helped solidify Union / Federal control over the mineral-rich area of the western Rocky Mountains. Statehood was regarded as fairly imminent with the expected growth in the constantly westward moving population, but the local territorial ambitions for full statehood were thwarted at the end of the war in 1865 by a constitutional veto by newly sworn in 17th President Andrew Johnson (1808-1875, served 1865-1869), who was a War Democrat who succeeded to the office after briefly only serving one month as Vice President after Lincoln's assassination that April. Statehood for the territory was a recurring issue during the subsequent Ulysses S. Grant presidential administration, with Republican 18th President Grant advocating statehood against a less willing Congress during the following post-war Reconstruction era (1865-1877). After a long constant lobbying campaign, the old Colorado Territory finally ceased to exist after only 15 years when the State of Colorado was admitted to the Union as the 38th state during the American Centennial celebrationn in August 1876[3]
The land that was eventually defined as the Colorado Territory was home to a number of indigenous civilizations. The Ute lived across both Western Colorado and the eastern high plains. The Anasazi lived in the southwestern, southern, and parts of southeastern Colorado. The Comanche and Jicarilla Apache lived in the area that would become the southeastern portions of the Territory. The Arapaho and Cheyenne also had a presence in the eastern and northeastern plains of the area at times.
Exploration by non-native peoples
The earliest explorers of European extraction to visit the area were Spanish explorers such as Coronado, although the Coronado expedition of 1540–42 only skirted the future border of the Colorado Territory to the south and southeast. In 1776, Francisco Atanasio Domínguez and Silvestre Vélez de Escalante explored southern Colorado in the Dominguez-Escalante Expedition.
In 1779, Governor de Anza of New Mexico fought and defeated the Comanches under Cuerno Verde on the Eastern Slope of Colorado, probably south of Pueblo. In 1786, de Anza made peace with the Comanches, creating an alliance against the Apaches.
A group of Cherokee crossed the South Platte and Cache la Poudre River valleys on their way to California in 1848 during the California Gold Rush. They reported finding trace amounts of gold in the South Platte and its tributaries as they passed along the mountains. In the south, in the San Luis Valley, early Mexican families established themselves in large land grants (later contested by the U.S.) from the Mexican government.
In the early 19th century, the upper South Platte River valley had been infiltrated by fur traders, but had not been the site of permanent settlement. The first movement of permanent U.S. settlers in the area began with the Kansas–Nebraska Act of 1854, which allowed private land claims to be filed. Among the first settlers to establish claims were former fur traders who returned to the lands they once trapped, including Antoine Janis and other trappers from Fort Laramie, who established a town near Laporte along the Cache la Poudre in 1858. See Forts in Colorado.
In 1858, Green Russell and a party of Georgians, having heard the story of the gold in the South Platte from Cherokee after they returned from California, set out to mine the area they described. That summer they founded a mining camp Auraria (named for a gold mining camp in Georgia) at the confluence of the South Platte and Cherry Creek. The Georgians left for their home state the following winter. At Bent's Fort along the Arkansas River, Russell told William Larimer, Jr., a Kansas land speculator, about the placer gold they had found. Larimer, realizing the opportunity to capitalize on it, hurried to Auraria. In November 1858, he laid claim to an area across Cherry Creek from Auraria and named it "Denver City" in honor of James W. Denver, the previous governor of the Kansas Territory. Larimer did not intend to mine gold himself; he wanted to promote the new town and sell real estate to eager miners.
Larimer's plan to promote his new town worked almost immediately, and by spring 1859 the western Kansas Territory along the South Platte was swarming with miners digging in river bottoms in what became known as the Colorado Gold Rush. Early arrivals moved upstream into the mountains quickly, seeking the lode source of the placer gold, and founded mining camps at Black Hawk and Central City. A rival group of civic individuals, including William A.H. Loveland, established the town of Golden City at the base of the mountains west of Denver City, with the intention of supplying the increasing tide of miners with necessary goods.
Territorial aspirations
The movement to create a territory within the present boundaries of Colorado followed nearly immediately. Citizens of Denver City and Golden City pushed for territorial status of the newly settled region within a year of the founding of the towns. The movement was promoted by William Byers, publisher of the Rocky Mountain News, and by Larimer, who aspired to be the first territorial governor. In 1859, settlers established the Territory of Jefferson, and held elections, but the United States Congress did not recognize the territory, and it never gained legal status.
Congressional grant of territorial status for the region was delayed by the slavery issue, and a deadlock between Democrats, who controlled the Senate, and the antislavery Republicans, who gained control of the House of Representatives in 1859. The deadlock was broken only by the Civil War. In early 1861, enough Democratic senators from seceding states resigned from the U.S. Senate to give control of both houses to the Republicans, clearing the way for admission of new territories. Three new territories were created in as many days: Colorado (February 28), Nevada (March 1), and Dakota (March 2).
Colorado Territory was officially organized by Act of Congress on February 28, 1861 (12Stat.172), out of lands previously part of the Kansas, Nebraska, Utah, and New Mexico territories. Technically the territory was open to slavery under the Dred Scott Decision of 1857, but the question was rendered moot by the impending American Civil War and the majority pro-Union sentiment in the territory. The name "Colorado" was chosen for the territory. It had been previously suggested in 1850 by Senator Henry S. Foote as a name for a state to have been created out of present-day California south of 35° 45'.
Civil War years
During the Civil War, the tide of new miners into the territory slowed to a trickle, and many left for the East to fight. The Missourians who stayed formed two volunteer regiments, as well as home guard. Although seemingly stationed at the periphery of the war theaters, the Colorado regiments found themselves in a crucial position in 1862 after the Confederate invasion of the New Mexico Territory by General Henry Sibley and a force of Texans. Sibley's New Mexico campaign was intended as a prelude to an invasion of the Colorado Territory northward to Fort Laramie, cutting the supply lines between California and the rest of the Union. The Coloradans, under the command of Union Army General Edward Canby and Colonel John P. Slough, Lt. Col. Samuel F. Tappan and Major John M. Chivington, defeated Sibley's force at the two day Battle of Glorieta Pass along the Santa Fe Trail, thwarting the Confederate strategy.
Colorado War between the U.S. and the Indians of Cheyenne and Arapaho
In 1851, by the Treaty of Fort Laramie, the United States acknowledged the Cheyenne and Arapaho tribes control, in the Colorado area, of the Eastern Plains between North Platte River and Arkansas River eastward from the Rocky Mountains. The Fort Laramie Treaty, in Article 2 of the treaty, did allow the U.S., government to build roads, military and other posts on Indian lands. If these roads could be used by U.S. citizens to lawfully pass through the Indian territories was not stated but apparently implied since the U.S. government bound itself to protect Indian nations against depredations by U.S. citizens. The treaty did not grant any rights for the erection of posts or settlements by U.S. civilians. Since this treaty was enacted before the railroads had come and before the finding of gold in the region, few whites had ventured to settle in what is now Colorado. By the 1860s, as a result of the Colorado Gold Rush and homesteaders encroaching westward into Indian terrain, relations between U.S. and the Native American people deteriorated. On February 18, 1861, in the Treaty of Fort Wise, several chiefs of Cheyenne and Arapaho supposedly agreed with U.S. representatives to cede most of the lands, ten years earlier designated to their tribes, for white settlement, keeping only a fragment of the original reserve, located between Arkansas River and Sand Creek. This new fragment was assigned in severalty to the individual members of the respective tribes with each member receiving 40 acres (160,000m2) of land. The United States, by the Fort Wise Treaty, wished to have the Indians settle the new reservation as farmers. The U.S. agreed to pay the tribes a combined total of $30,000 per year for 15 years and in addition to provide a lumber mill, one or more mechanic shops, dwelling houses for an interpreter, and a miller engineer. See Article 5 of the Fort Wise Treaty.
A good part of their co-nationals repudiated the treaty, declared the chiefs not empowered to sign, or bribed to sign, ignored the agreement, and became even more belligerent over the 'whites' encroaching on their hunting grounds. Tensions mounted when Colorado territorial governor John Evans in 1862 created a home guard of regiments of Colorado Volunteers returning from the Civil War and took a hard line against Indians accused of theft. On August 21, 1864, a band of 30 Indians attacked four members of the Colorado Cavalry as they were rounding up stray cattle. Three of the members made it back to the stockade at Franktown, Colorado, but the fourth man failed to return. This man, Conrad Moschel, was found a few days later having been shot with a firearm and pierced with an arrow, and had been scalped in the manner of the Cheyenne. This offensive action by the warring Cheyenne further enraged the U.S. people of Colorado. After several minor incidents in what would later come to be designated as the Colorado War, in November 1864, a force of 800 troops of the Colorado home guard, after heavy drinking, attacked an encampment of Cheyenne and Arapaho at Sand Creek, murdering between 150 and 200 Indians, mostly elderly men, women and children. This Sand Creek Massacre or 'Massacre of Cheyenne Indians' led to official hearings[5] by the United States Congress Joint Committee on the Conduct of the War in March and April 1865. After the hearings, the Congress Joint Committee in their report on May 4, 1865, described the actions of Colonel John Chivington and his Volunteers as "foul, dastardly, brutal, cowardly" and:
It is difficult to believe that beings in the form of men, and disgracing the uniform of United States soldiers and officers, could commit or countenance the commission of such acts of cruelty and barbarity as are detailed in the testimony, but which your committee will not specify in their report.
Nevertheless, justice was never served on those responsible for the massacre; and nonetheless, the continuation of this Colorado War led to expulsion of the last Arapaho, Cheyenne, Kiowa and Comanche from the Colorado Territory into Oklahoma.
The movement for statehood
Following the end of the American Civil War, a movement was made for statehood; the United States Congress passed the Admission Act for the territory in late 1865, but it was vetoed by President Andrew Johnson. For the next eleven years, the movement for territorial admission was stalled, with several close calls. President Grant advocated statehood for the territory in 1870, but Congress did not act.
In the meantime, the territory found itself threatened by lack of railroads. By the late 1860s, many in Denver had sold their businesses and moved northward to the Dakota Territory communities of Laramie and Cheyenne, which had sprung up along the transcontinental railroad. Faced with the possible dwindling of the town and its eclipse by the new towns to the north, Denverites pooled their capital and built the Denver Pacific Railroad northward to Cheyenne to bring the rail network to Denver. The Kansas Pacific Railway was completed to Denver two months later. The move cemented the role of Denver as the future regional metropolis. The territory was finally admitted to the Union in 1876.
Territorial capitals
Three Colorado cities served as the capital of the Territory of Colorado:
Denver City: from creation on February 28, 1861, until July 7, 1862.
For much if not all of its existence, the Colorado Territorial government did not actually own its houses of government, instead renting available buildings for governmental purposes. Today, two buildings which served the Territorial government remain: the historic log building in Colorado City, and the Loveland Block in downtown Golden City (which had housed the complete legislature, Territorial Library and possibly Supreme Court from 1866 to 1867, with library remaining to 1868). Others which served include the original Loveland Building (1859–1933, 1107 Washington Avenue in Golden, housing the Territorial House from 1862 to 1866); the Overland Hotel (1859–1910, 1117 Washington Avenue in Golden, housing the Territorial Council from 1862 to 1866); and the Territorial Executive Building (unknown dates, approximately 14th and Arapahoe Streets in Golden, housing the executive branch of the government from 1866 to 1867).
The Cheyenne are an Indigenous people of the Great Plains. The Cheyenne comprise two Native American tribes, the Só'taeo'o or Só'taétaneo'o and the Tsétsêhéstâhese ; the tribes merged in the early 19th century. Today, the Cheyenne people are split into two federally recognized nations: the Southern Cheyenne, who are enrolled in the Cheyenne and Arapaho Tribes in Oklahoma, and the Northern Cheyenne, who are enrolled in the Northern Cheyenne Tribe of the Northern Cheyenne Indian Reservation in Montana. The Cheyenne language belongs to the Algonquian language family.
Indian Territory and the Indian Territories are terms that generally described an evolving land area set aside by the United States government for the relocation of Native Americans who held original Indian title to their land as an independent nation-state. The concept of an Indian territory was an outcome of the U.S. federal government's 18th- and 19th-century policy of Indian removal. After the American Civil War (1861–1865), the policy of the U.S. government was one of assimilation.
Larimer County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 359,066. The county seat and most populous city is Fort Collins. The county was named for William Larimer, Jr., the founder of Denver.
The Sand Creek massacre was a massacre of Cheyenne and Arapaho people by the U.S. Army in the American Indian Wars that occurred on November 29, 1864, when a 675-man force of the Third Colorado Cavalry under the command of U.S. Volunteers Colonel John Chivington attacked and destroyed a village of Cheyenne and Arapaho people in southeastern Colorado Territory, killing and mutilating an estimated 70 to over 600 Native American people. Chivington claimed 500 to 600 warriors were killed. However, most sources estimate around 150 people were killed, about two-thirds of whom were women and children. The location has been designated the Sand Creek Massacre National Historic Site and is administered by the National Park Service. The massacre is considered part of a series of events known as the Colorado Wars.
John Milton Chivington was a Methodist pastor and Mason who served as a colonel in the United States Volunteers during the New Mexico Campaign of the American Civil War. He led a rear action against a Confederate supply train in the Battle of Glorieta Pass that had the effect of ending the Confederacy's campaigns in the Western states, and was then appointed a colonel of cavalry during the Colorado War.
The region that is today the U.S. state of Colorado has been inhabited by Native Americans and their Paleoamerican ancestors for at least 13,500 years and possibly more than 37,000 years. The eastern edge of the Rocky Mountains was a major migration route that was important to the spread of early peoples throughout the Americas. The Lindenmeier site in Larimer County contains artifacts dating from approximately 8720 BCE.
The territory of the United States and its overseas possessions has evolved over time, from the colonial era to the present day. It includes formally organized territories, proposed and failed states, unrecognized breakaway states, international and interstate purchases, cessions, and land grants, and historical military departments and administrative districts. The last section lists informal regions from American vernacular geography known by popular nicknames and linked by geographical, cultural, or economic similarities, some of which are still in use today.
The Provisional Government of the Territory of Jefferson was an extralegal and unrecognized United States territory that existed in the Pike's Peak mining region from October 24, 1859, until it yielded to the new Territory of Colorado on June 6, 1861. The Jefferson Territory, named for Founding Father and third United States president Thomas Jefferson, included land officially part of the Kansas Territory, the Nebraska Territory, the New Mexico Territory, the Utah Territory, and the Washington Territory, but the region was remote from the governments of those five territories.
James William Denver was an American politician, soldier and lawyer. He served in the California state government, as an officer in the United States Army in two wars, and as a Democratic member of the United States House of Representatives from California. He served as secretary and Governor of the Kansas Territory during the struggle over whether or not Kansas would be open to slavery. The city of Denver, Colorado, is named after him.
The Sioux Wars were a series of conflicts between the United States and various subgroups of the Sioux people which occurred in the later half of the 19th century. The earliest conflict came in 1854 when a fight broke out at Fort Laramie in Wyoming, when Sioux warriors killed 31 American soldiers in the Grattan Massacre, and the final came in 1890 during the Ghost Dance War.
The Colorado War was an Indian War fought in 1864 and 1865 between the Southern Cheyenne, Arapaho, and allied Brulé and Oglala Sioux peoples versus the U.S. Army, Colorado militia, and white settlers in Colorado Territory and adjacent regions. The Kiowa and the Comanche played a minor role in actions that occurred in the southern part of the Territory along the Arkansas River. The Cheyenne, Arapaho, and Sioux played the major role in actions that occurred north of the Arkansas River and along the South Platte River, the Great Platte River Road, and the eastern portion of the Overland Trail. The United States government and Colorado Territory authorities participated through the 1st Colorado Cavalry Regiment, often called the Colorado volunteers. The war was centered on the Colorado Eastern Plains, extending eastward into Kansas and Nebraska.
Camp Collins was a 19th-century outpost of the United States Army in the Colorado Territory. The fort was commissioned in the summer of 1862 to protect the Overland Trail from attacks by Native Americans in a conflict that later became known as the Colorado War. Located along the Cache la Poudre River in Larimer County, it was relocated from its initial location near Laporte after a devastating flood. Its second location downstream on the Poudre was used until 1866 and became the nucleus around which the City of Fort Collins was founded.
The Fort Laramie Treaty of 1851 was signed on September 17, 1851 between United States treaty commissioners and representatives of the Cheyenne, Sioux, Arapaho, Crow, Assiniboine, Mandan, Hidatsa, and Arikara Nations. Also known as Horse Creek Treaty, the treaty set forth traditional territorial claims of the tribes.
The Treaty of Fort Wise of 1861 was a treaty entered into between the United States and six chiefs of the Southern Cheyenne and four of the Southern Arapaho Indian tribes. A significant proportion of Cheyennes opposed this treaty on the grounds that only a minority of Cheyenne chiefs had signed, and without the consent or approval of the rest of the tribe. Different responses to the treaty became a source of conflict between whites and Indians, leading to the Colorado War of 1864, including the Sand Creek Massacre.
Chief Niwot or Left Hand(-ed) was a Southern Arapaho chief, diplomat, and interpreter who negotiated for peace between white settlers and the Cheyenne and Arapaho tribes during the Pike's Peak Gold Rush and Colorado War.
This is an alphabetical list of articles related to the U.S. State of Colorado.
Little Raven, also known as Hosa, was from about 1855 until his death in 1889 a principal chief of the Southern Arapaho Indians. He negotiated peace between the Southern Arapaho and Cheyenne and the Comanche, Kiowa, and Plains Apache. He also secured rights to the Cheyenne-Arapaho Reservation in Indian Territory.
Fort Weld, also called Camp Weld, began as a military camp on 30 acres east of the Platte River in what is now the La Alma-Lincoln Park neighborhood of Denver, Colorado. It was named for Lewis Ledyard Weld, the first Territorial Secretary. The central square of the post was used to practice drills of the troops. Buildings—soldier's quarters, officers' headquarters, mess rooms, a hospital, and a guard house—surrounded the square. The main entrance to the camp was on the eastern side of the post. It was established in September 1861 and abandoned in 1865.
Margaret Poisal was "the only woman who was an official witness, interpreter, and consultant at many meetings and treaty councils held along or in close proximity to the Santa Fe Trail." The daughter of French Canadian trapper John Poisal and Arapaho Snake Woman, Poisal was educated at a convent school. She married Thomas Fitzpatrick, an Indian agent, and they worked together negotiating peace between Native American tribes and the United States government. After Fitzpatrick died, Poisal continued to work as an interpreter and peacemaker.
