Chief Ouray – At age seventeen Ouray, "The Arrow", became Chief of the Uncompahgre Tribe of the Ute Nation, a nation that desperately needed a diplomatic leader. The multi-lingual Chief Ouray visited with President Grant, and in 1868 signed over the tribes' ancestral claims to the San Luis Valley in order to preserve further encroachment onto Indian lands in the San Juans. This uneasy peace was broken by miners who began blasting the mineral rich San Juan Mountains, or as Chief Ouray called them the "Shining Mountains." Chief Ouray believed that the Utes had no choice but to surrender these lands, but many tribes within the Ute Nation chose instead to fight. The infamous Meeker Massacre in Rio Blanco County was the result of the animosity that developed between the Utes and the encroaching white settlers. Ultimately, the United States forced the Native Americans onto new reservations. President Hayes never lost his respect for Chief Ouray, describing him in 1880 as the "most intelligent man I've ever conversed with." In a time of change, strife, and challenge Chief Ouray was honored by both Ute and non-Indian people.

Horace Tabor – Miner, merchant, bonanza king, Tabor joined the gold rush to Colorado in 1859. He arrived in Denver, June 20, 1859, from Kansas. Engaged in prospecting, merchandising, and grubstaking in early mining camps and Leadville, Tabor  achieved phenomenal financial success with discovery of silver in holdings in Little Pittsburgh Mine, May 3, 1878. He became a public figure, serving as first mayor of Leadville in 1878; and County Treasurer in 1880. He later made residence in Denver and served as postmaster of Denver, January 4, 1898, until his death.

He took his money and made various fortunes in many Colorado industries such as meatpacking, sugar, and railroads. His name lives on through the philanthropic work of the Boettcher Foundation.

Barney Ford – Born a slave in Virginia, Barney Ford taught himself how to read and write. At the age of twenty five he ran away from slavery to Chicago, and two years later headed west to seek his fortune. Ford went to Nicaragua and became owner of two hotels, but when slavery was restored there, Barney and his wife returned to Chicago to help slaves escape into free Canada. In 1858 Ford headed west again, but this time he went to Denver. By the time the 13th Amendment passed in 1865, Ford was already being called the "Black Baron of Colorado."

Even though one of these railroads, the Denver Northwestern and Pacific line, only reached to Steamboat Springs at the time of Moffat's death, the development of the 6.3 mile long Moffat Tunnel through the Continental Divide soon after allowed important intercontinental railroad traffic to go over the daunting Rocky Mountains. Moffat's work with the transportation industry helped to make Denver the railroad hub for the West, and as such established Colorado as a nationally important commercial and industrial center. 



Colorado Government

The discovery of gold in 1858 brought people to the fledgling towns of Denver City, Auraria and other front range mining camps. The new inhabitants quickly realized the need for some form of government and movement began toward a territorial and a subsequent state government which led up to the admittance of Colorado as the 38th state of the Union on August 1, 1876.

Chronology of the Colorado Constitution: Eighteen Years to Statehood

The following chronology describes the events that led up to the acceptance of Colorado's State Constitution in 1876.  

November, 1858  Denver citizens formed the independent government of Arapahoe County within Kansas Territory and elected a delegate. First constitutional convention met in Blake and Williams Hall on Blake Street in Denver.  

September, 1859  First constitution rejected, but a provisional territorial government called the Territory of Jefferson was formed.  

February, 1861  Congress created the Territory of Colorado, headed by William Gilpin.  

August-September, 1861  First Legislative Assembly elected and convened.  

January 5, 1863  Territorial delegate Hiram P. Bennet introduced a bill to provide statehood for Colorado but it did not pass the House.  

1864   Another constitutional convention elected and a constitution drafted but later defeated by public vote.  

1865   A new constitution framed and approved in a general election but vetoed by President Johnson.  

1869-1873 Each session of Congress received Colorado Statehood Bills but did not pass them.  

December, 1873  President Grant recommended an Enabling Act for the admission of Colorado as a state.  

January, 1874  Jerome Chaffee, Colorado Territory's delegate to Congress, introduced House Bill 435 for provision of a state government.  

June 8, 1874 - March 3, 1875  Bill 435 passed the House, was amended and passed by the Senate and signed by the President.

The Constitutional Convention of 1875 

The year was 1876. Thirty-nine members of the constitutional convention convened on December 20th. The total population of Colorado Territory was approximately 100,000 and a major railroad connected the territory. Knowing the time was now right for statehood, many dedicated delegates traveled almost 1000 miles over mountains and through heavy snowstorms to attend the convention at the Odd Fellow Hall in Denver. They spent 87 days preparing the constitution, taking months longer than the two earlier attempts. Committees carefully examined such topics as the control of corporate bodies, the disposition of public waters and lands, the forming and maintaining of a public school system, taxation of property, non-residents against debts, and the right to suffrage.  

The constitution, completed on March 14, 1876, was modeled after the Nation's constitution. Beginning with the Bill of Rights which guaranteed all national and civil rights, it set the terms and duties of government officials and the ways in which a law could be introduced and passed. It established the State Supreme Court, district courts and county courts. It provided for the supervision and maintenance of public schools. The constitution also determined that a state census be taken in 1885 and every ten years afterward. It designated the elimination of dormant corporations. It regulated railroad lines and set up a system for state tax. Finally, it allowed for future amendments of the constitution. When submitted to the citizens for vote, 15,443 favored the constitution from a total of 19,505 votes.  

Colorado's original constitution was handwritten by Fred J. Stanton, the engrossing and enrolling clerk for the constitutional convention. A copy was then penned from the original by the assistant engrossing and enrolling clerk, W.A. Salisbury. On July 25, 1876, Governor Routt dispatched his secretary, John N. Reigart, to Washington, D.C. with the copy of the constitution along with certified ordinances, votes and proclamations. President Grant declared Colorado a state on August 1, 1876 and it became known as the "Centennial State." Since then, the constitution has been the foundation of the State's government and the citizen's freedom. Colorado's constitution today remains very similar to the original constitution conceived for statehood in 1876. The original is preserved in the Colorado State Archives.

Copies of the Proceedings of the Constitutional Convention can be accessed on our History of the Colorado State Constitution webpage.
