History
Indigenous peoples originally inhabited the region, with the Clovis culture representing the earliest documented population to establish settlement in this territory.
Longmont was founded in 1871 by a group of people from Chicago, Illinois. Originally called the Chicago-Colorado Colony, led by president Robert Collyer, the men sold memberships in the town, purchasing the land necessary for the town hall with the proceeds. As the first planned community in Boulder County, the city streets were laid out in a grid plan within a square mile. The Longmont, Colorado Territory, post office opened on April 14, 1873. The city began to flourish as an agricultural community after the Colorado Central Railroad line arrived northward from Boulder in 1877. The Town of Longmont was incorporated on November 15, 1885.
In 1925, the Ku Klux Klan gained control of Longmont's City Council in an election. They began construction of a large pork-barrel project, Chimney Rock Dam, above Lyons and marched up and down Main Street in their costumes. In the 1927 election they were voted out of office, and their influence soon declined. Work on Chimney Rock Dam was abandoned as unfeasible, and its foundations are still visible in the St. Vrain River.
In 1955, United Airlines Flight 629 exploded over Weld County, Colorado, 8 miles east of Longmont, killing 44 passengers and crew.
