List Of County Seats In Colorado
This is a list of the county seats of the U.S.
Territory of Jefferson
On August 24, 1859, voters of the Pike's Peak mining region approved the formation of the Provisional Government of the Territory of Jefferson and designated Denver City as the capital. On November 28, 1859, the territory established 12 counties which served as the de facto local government. The extralegal territory was unable to secure authorization from the United States Congress embroiled in the debate over slavery. On November 13, 1860, the territory moved its capital to Golden City. On February 28, 1861, after seven slave states seceded from the Union, U.S. President James Buchanan signed An Act to provide a temporary Government for the Territory of Colorado. On June 6, 1861, the Jefferson Territory officially yielded to the new Territory of Colorado.
