In the 1880s, Frederick was nothing but prairieland, and its only inhabitants were prairie dogs, rabbits, coyotes, and snakes. Coal brought settlers to the area, and Frederick was incorporated in 1907 as a coalmining town. The mines needed workers, and immigrants arrived from across the globe to help fill this need for labor. Men and their families came from Italy, Russia, Turkey, Greece, Mexico, and the Slavic countries to make Frederick their home. While not considered a gold or silver boomtown, Frederick had its share of growing pains. Liquor and illegal gambling were constant sources of problems, and the town saw natural disasters such as persistent flooding as well. As its location on the Union Pacific Railroad helped the miners, farmers, and merchants build a strong community, the history of Frederick provides a classic example of growth and development on the eastern Colorado plains.
