Clay County, Minnesota: History
Breckenridge County was created on March 18, 1858. Clay County was established on November 2, 1860 as Breckinridge County and named for John C. Breckinridge, vice president of the United States from 1857 to 1861. After the Civil War began, Breckinridge joined the Confederate Army and in March 1862 the state Legislature replaced the name of Breckinridge with that of Henry Clay (1777–1852), who like Breckinridge was from Lexington, Ky., and was known "The Great Pacificator" or "The Great Compromiser" who helped head off civil war at least twice. The county's government was not organized until 1872, after the Northern Pacific Railway reached the area and settlement accelerated.
