If you are seeking details for a Colorado genealogy project, you can do so from home or within a large number of archives and other locations. This is because there is no single route to research, and because there are resources available in both the online and “offline” formats.

In the current era it is exciting to learn that many things once only archived in private locations have been digitized and put on the Internet. We must also accept, however, that some still have yet to be made available to the public. This means that an effective first step in research for Colorado genealogy is to find out which records are available, and how to get them.

In the 1500s, Spanish explorers first came to what is now Colorado. However, the area wasn’t actually claimed for Spain until 1706. It was claimed by Juan de Ulibarri. In 1803, the eastern part of present-day Colorado was handed over to the United States as part of the Louisiana Purchase. When Texas became a state, which was in 1845, the central part of what is now Colorado came under U.S. control. Then, in 1848, after the Mexican War, the United States obtained the western part of Colorado.
