The Jefferson Territory never received federal sanction, but on February 28, 1861, U.S. President James Buchanan signed an act organizing the Territory of Colorado. On November 1, 1861, the Colorado General Assembly organized 17 counties, including Weld County, for the new Colorado Territory. Weld County was named for Lewis Ledyard Weld, a lawyer and territorial secretary. He died while serving in the Union Army during the Civil War.

Weld County was thrust into the media spotlight on the evening of November 1, 1955, when United Airlines Flight 629, a Douglas DC-6B airliner flying from Denver to Portland, Oregon, exploded in midair and crashed, killing all 44 persons on board the plane and scattering bodies, wreckage and debris over a six-square-mile area of the county. The subsequent investigation of the accident revealed that Denver resident John Gilbert Graham had secretly placed a time bomb composed of 25 sticks of dynamite in a suitcase belonging to his mother, who was a passenger on the airplane. Graham was tried and convicted of the crime, and executed in 1957.
