Newton Knight was an American farmer, soldier and Southern Unionist in Mississippi, best known as the leader of the Knight Company, a band of Confederate Army deserters who resisted the Confederacy during the Civil War. Local legends tell of Knight and his men forming the "Free State of Jones" in the area in and around Jones County, Mississippi, at the height of the war. The nature and extent of the Knight Company's opposition to the Confederate government is disputed among historians. After the war, Knight joined the Republican Party and served in Mississippi's Reconstruction government as a deputy U.S. Marshal.

In the United States, Southern Unionists were white Southerners living in the Confederate States of America opposed to secession. Many fought for the Union during the Civil War. These people are also referred to as Southern Loyalists, Union Loyalists, or Lincoln's Loyalists. Pro-Confederates in the South derided them as "Tories". During Reconstruction, these terms were replaced by "scalawag", which covered all Southern whites who supported the Republican Party.
