When at first you don’t succeed, try, try, and try again. Colorado became the 38th state of the Union in 1876, but only after more than 15 years of overcoming various roadblocks and multiple rejections. According to Thomas B. Corbett’s brief history of Colorado included in The Legislative Manual of the State of Colorado1, much of Colorado and its scattered population of trappers, hunters, traders, various Native American tribes, and Mexican citizens existed with only sporadic local law protection. Residents also lived without legislative representation in the Kansas territorial legislature, even though the region was part of the Kansas Territory from 1854 to 1861.
The Colorado Gold Rush, starting in 1858, quickly attracted 20,000 inhabitants to the mining areas. With another 80,000 or so new residents arriving over the next few years, the urgency increased for an accessible and organized government in Colorado in order to more adequately protect life and property.
Thus, in 1858 and 1859, Colorado citizens petitioned Congress to establish a government separate from the distant one assigned to them in Kansas. In April of 1859, interested parties in Colorado met to discuss organizing a new territory or state. The prevailing sentiment of the group was to pursue statehood directly. A convention of delegates was formed, and a state constitution was drafted and finalized by that August.
The constitution and the question of pursuing statehood were sent to the people for approval and were subsequently rejected. But the convention delegates had prepared for this outcome and had resolved that, should the state constitution be rejected, an emissary be elected to represent the Jefferson Territory to Congress and for a new slate of delegates be chosen to form a provisional territorial government. A new constitution, called the “Organic Act of the Territory of Jefferson,” was framed and adopted, and the elected emissary was sent to memorialize Congress to separate the Pike’s Peak region from Kansas. The endeavor was unsuccessful in Congress, but those pesky Coloradans remained undeterred, and the Jefferson Territory Provisional Government continued to operate without Congressional approval.
On January 29, 1861, Kansas became a state, and then, on February 28, 1861, Congress passed a bill2 providing for the political organization and administration of the Colorado Territory and drawing the boundaries of the new territory, mainly from the western portion of the Kansas Territory, as well as smaller segments of the Nebraska, Utah, and New Mexico territories. Obtaining statehood remained the final goal of the territorial government. In spite of the Confederacy secession from the Union and the ensuing Civil War, upon petition from the Colorado legislature, Congress passed and President Abraham Lincoln signed a bill enabling the territory to organize a state government in order to enter the Union. A convention of delegates met in Denver on July 4, 1864, and framed a state constitution, which was then rejected by the people the following October.
Down but not out, interested parties decided to make another attempt at statehood in 1865, and another convention met that August to frame a state constitution, which was adopted by the people. State officers and a state legislature were elected the following November, and delegates presented the application to Congress twice, with it passing twice. Subsequently it was vetoed twice by President Andrew Johnson, purportedly due to Colorado’s low population numbers. After Johnson left office in 1869, Congress failed to pass a statehood bill for Colorado on three separate occasions between 1869 and 1873.
Fast forward to March 3, 1875, when a president amenable3 to Colorado statehood encouraged Congress to consider “An act to enable the people of Colorado to form a constitution and State government, and for the admission of said State into the Union on an equal footing with the original States”.4 After several amendments, the bill passed with a stipulation: Coloradans must pass or reject a state constitution in a vote in July of 1876.
Colorado’s Constitutional Convention of 1875–1876 was held at the Odd Fellows’ Hall, located on the third floor of the First National Bank at the corner of 16th and Blake Streets. (The facility, later dubbed “Constitution Hall,” burned to the ground in 1977.) With the population of the territory well over 100,000 and more arriving on the major railroad now connecting the state with the rest of the country, it seemed like the time for statehood was now or never.
The 39 delegates of the constitutional convention worked from December 20, 1875, to March 15, 1876, to create and finalize the constitution. Delegates were divided into committees to frame and present topics of the constitution for discussion and, at times, extended debate. These topics included the judiciary; education and educational institutions; suffrage; corporations; revenue and finances; mines and mining; water and irrigation; agriculture and manufacturing; military affairs; state, county and municipal debt; forest culture; and citizen rights. The final constitution, modeled after the U.S. Constitution and other state constitutions, started with a Bill of Rights and allowed for future amendments to be made to the constitution.
Printed for citizen review in three languages and voted on July 1, 1876, the 1876 state constitution5 was approved by 15,443 to 4,062 (79% to 21%). On August 1, 1876, President Ulysses S. Grant signed Proclamation 230,6 admitting the State of Colorado to the Union as the 38th state and as the one and only Centennial State.
Although official records or journals of convention activity were not published during or immediately after the convention, there was extensive newspaper coverage available for those unable to attend. Finally in 1907, Senate Bill 217 directed the Secretary of State to prepare all records of the 1876 Constitutional Convention in book form. In August of that year a Proceedings of the Constitutional Convention8 was published.
The 1876 Colorado Constitution
The Constitution of the State of Colorado, written and ratified in 1876, laid the framework for the state’s government. The original, hand-written constitution was 40 pages long and was and remains one of the longest state constitutions on record. It left power in the hands of the people through a representational government and granted the ability to hold referenda on laws and constitutional amendments enacted by the legislature. In 1910, the Initiative and Referendum Amendment empowered Coloradans to draft proposed statutes or constitutional amendments, gather signatures on petitions, and have their proposals presented to the voters for approval.
Some little-known provisions of the 1876 constitution included:
- Until 1900, laws passed at each session were to also be published in Spanish and German in a sufficient number of copies to supply the new laws to that portion of the inhabitants of the State who speak those languages and who may be unable to read and understand the English language.9 (In 1988, a citizens’ initiative added an English-only provision.)
- The Colorado Supreme Court consisted of three judges who were elected and served fixed 9-year terms.10 Today, the Supreme Court consists of seven justices who are appointed by the governor and are subject only to removal through retention elections. (The current structure was established by an amendment to the constitution adopted in 1966.)
- The Governor of Colorado served a two-year term11, similar to many other states at that time. By the late 20th century, nearly all states had converted to four-year terms. (An amendment was passed in 1956 extending the governor’s term to four years.)
- The Constitution suggested that the General Assembly adopt laws allowing women’s suffrage. It mandated universal suffrage for males over 21 years of age but stipulated that the General Assembly, at its first session, “enact laws to extend the right of suffrage to women of legal age.”12 Although that did not happen in that first legislative session, Colorado would eventually extend suffrage to women in a state referendum in 1893 – more than 25 years before America adopted women’s suffrage at the national level.
- Slavery is specifically prohibited. The Colorado constitution specifically stated that “[t]here shall never be in this State either slavery or involuntary servitude…”.13
This year, we commemorate Colorado’s 150th Anniversary as a state and America’s 250th Anniversary as a nation. Celebrations will be held throughout the country, but as the only Centennial state, Colorado is celebrating two anniversaries this year. You can find more information on the America 250 Colorado 150 anniversary celebrations scheduled throughout the state on the Colorado History website.
