History

Formed in 1873 from Billings County and Norton County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Decatur County was created on March 20, 1873, from Non-County Area 6 and initially attached to Billings (now Norton) for judicial purposes. The county became fully organized in 1879 and was detached from Norton. The county is named after Stephen Decatur.
