Anniversary Celebrations
An anniversary is commonly associated with weddings. Married persons who regard the date of their marriage as important may mark the yearly date of their wedding in some special way.
Broader groups in society, especially the families, and even more especially the children of such a couple, may help to celebrate such occasions; this is particularly common on the 40th, 50th, and 60th annivs.
Retailers (especially jewellers), sensing a profit opportunity, have encouraged gift-giving on such special days, and may often suggest a hierarchy of types of gifts to reflect the importance of longer years of marriage (and perhaps of greater ability to purchase more expensive gifts).
The state was named after the Spanish word "Colorado," which means "reddish colored" that presumably refers to the red sandstone formations in the area or reddish brown color of the Colorado River.
The territory that ultimately became Colorado was added to the United States by the 1803 Louisiana Purchase and the 1848 Mexican Cession. The Colorado Gold Rush of 1859 brought many settlers to the Denver area, though the population collapsed following an initial mining boom. The Colorado Territory was organized as a United States territory on February 28, 1861, and Colorado attained statehood August 1, 1876, (earning it the moniker the "Centennial State"). Colorado women were granted the right to vote starting on November 7, 1893.
