Colorado's Historic Milestone: A Century and a Half in the Union
On this day in history, Colorado marks 150 years since its admission to the United States, a milestone recorded on August 1, 1876, when President Ulysses S. Grant signed the proclamation officially ratifying Colorado as the 38th state in the Union, as documented by the Library of Congress.
The region's history stretches far earlier than its statehood. Early inhabitants included agricultural cliff‑dwelling societies, followed centuries later by Spanish expeditions such as Francisco Vásquez de Coronado's 1540s exploration. Interest in the region intensified in the late 1850s when gold discoveries near Central City drew thousands of prospectors, according to historical summaries from History.com.
Mining camps and ranching communes became central to early territorial life. Historical accounts compiled by the Aspen Times note that miners and ranchers influenced Colorado's early economy, influenced settlement patterns, and contributed to the territorial push toward organized governance.
Original Coloradans
Research from the Library of Congress and documentary work by PBS identify Colorado's earliest known inhabitants as Indigenous nations including the Ute, Cheyenne, Arapaho, and Apache peoples. These populaces developed cultural traditions, trade networks, and seasonal migration patterns long before European or American settlement.
Early American Settlement
According to early settlement records preserved by Grand County, American migration into Colorado increased significantly during the mid‑1800s. Settlers established homesteads, ranches, and agricultural networks across mountain valleys and plains regions, often near water sources, transportation routes, and mining districts.
Local history guides from the Library of Congress note that these communities contributed to the territorial population growth that later supported Colorado's bid for statehood.
Political organization began with the establishment of the Colorado Territory in 1861. Several proposed constitutions were rejected, and Congress declined earlier admission attempts. The 1875 enabling act finally authorized Colorado to draft a constitution meeting federal requirements, including taxation rules, water rights provisions, and limits on state borrowing, as outlined in EBSCO Research Starters.
Delegates convened in late 1875 for the constitutional convention, working through early 1876 to produce the document required for admission. Their work coincided with national celebrations approaching the centennial of the Declaration of Independence.
Voters approved the new constitution on July 1, 1876. Reports describe crowds filling the streets on July 4 as thirty‑eight ceremonial shots were fired to symbolize Colorado's anticipated place as the thirty‑eighth state.
On August 1, 1876, President Grant issued the proclamation admitting Colorado to the Union. The date has since remained a significant marker in Colorado's history, commemorated annually as Colorado Day.
Early Settlers Day – La Junta
In La Junta, Early Settlers Day remains one of the community's longest‑running traditions. According to event organizers and historical descriptions from Colorado.com, the celebration takes place annually in City Park and features historic demonstrations, vendors, food booths, games, and family‑friendly activities that highlight pioneer heritage.
The celebration connects local history with Colorado's broader territorial story, including the miners, ranchers, Indigenous cultures, and agricultural families who contributed to the transformation of southeastern Colorado.
As Colorado observes its sesquicentennial, communities across the state continue to highlight the events, traditions, and historical evolutions that tailored its entry into the Union. Early Settlers Day serves as a reminder of the stories preserved in towns like La Junta.
