Carbon County was organized in 1868.

Originally about 3,400 square miles (8,800 km2) in the center of Carbon County were once part of the Spanish Empire, then part of the Republic of Texas (1835-1845) and part of the State of Texas until 1852 when the northernmost part of that state was ceded to the U.S. government. This area is defined by the 42nd parallel on the north, and straight lines south from there to the headwaters of the Arkansas river on the east and the headwaters of the Rio Grande on the west. The documents defining that area include the Adams-Onís Treaty of 1819, the 1824 Constitution of Mexico, and the 1845 "Joint Resolution for the Admission of the State of Texas into the Union".

Carbon County was organized December 16, 1868, from
