1. On December 5, 1876, Colorado was officially admitted as the 38th state in the United States. This followed a long period of territorial status and a growing population of settlers and miners in the region.

3. On December 5, 2008, the Colorado Rockies traded star outfielder Matt Holliday to the Oakland Athletics in exchange for a package of players, including Carlos Gonzalez, who would go on to become another star for the Rockies. Holliday had been an integral part of the team's run to the World Series in 2007.

4. In 1976, the Winter Olympics were held in Innsbruck, Austria, and included several athletes from Colorado who competed in various events. Among them were downhill skier Cindy Nelson, speed skater Sheila Young, and figure skater Terry Kubicka.

5. On December 5, 1914, suffragists in Colorado held a rally at the state capitol in Denver to call for women's right to vote. This was several years before the 19th Amendment was ratified, but Colorado had already granted suffrage to women in 1893, making it one of the first states to do so. The rally was part of a nationwide movement for women's suffrage that ultimately led to the passage of the amendment.
