The word “Colorado” comes from the Spanish word for “colored red.” The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state.
Colorado is nicknamed the “Centennial State” because it became a state one century (100 years) after the signing of the United States Declaration of Independence in 1776.
