[edit] History
Jefferson County was one of the original 17 Colorado counties created by the new Colorado Territory on November 1, 1861. Jefferson County was named after the extralegal Jefferson Territory, which in turn was named after U.S. President Thomas Jefferson. In 1908, the southern tip of Jefferson County was transferred to Park County, reducing Jefferson County to its present length of 54 miles (87 kilometers). Several annexations by the City and County of Denver and the 2001 consolidation of the City and County of Broomfield removed eastern portions of the county.
The Columbine High School massacre occured on April 20, 1999, in the Columbine Area of Jefferson County.
Jefferson County is often nicknamed Jeffco. The name Jeffco is incorporated in the official name of the North Jeffco Park and Recreation District, the Jeffco Business Center Metropolitan District No. 1, and several businesses located in Jefferson County. Jeffco is also incorporated in the unofficial monikers of many Jefferson County agencies. The Rocky Mountain Metropolitan Airport operated by Jefferson County was previously known as the Jeffco Airport.
