This was part of the Miro District (also spelled Mero), named after the Spanish GovernorEsteban Rodríguez Miró of what was then Louisiana on the west side of the Mississippi River. Miró had served with Spanish troops that assisted the Americans duringtheir war for independence.James Robertson, the explorer for whom this county was named, was trying to create an alliance with Miró that would allow free movement on the Mississippi River (which Spain controlled) to settlers on the Cumberland frontier. Before statehood, this territory was known as Tennessee County.
Thomas Kilgore, the first European settler in Robertson County, arrived in 1778 to establish a settlement in what is now present-dayCross Plains. Robertson County was organized in 1796, at the same time as Montgomery County, which had also been part of the Miro district. The county seat,Springfield, Tennessee, was laid out in 1798. Although initially, most settlers did not hold slaves, by the 1820s planters began to cultivate tobacco, a commodity crop that was labor-intensive and depended onenslaved African Americans. The planters bought slaves to work their plantations, as well as to care for the livestock they bred - thoroughbred horses and cattle.
By the time of theCivil War, African Americans comprised about one-quarter of the area's population, typical forMiddle Tennessee, where tobacco and hemp were commodity crops. During the Civil War, Tennessee was occupied by the Union from 1862, which led to a breakdown in social organization in Middle Tennessee.[3]
By 1910 the county's population was 25,466, including 6,492 black citizens, who continued to make up one-quarter of the total. Most of the residents were still involved in farm work, and tobacco was the primary commodity crop, but agricultural mechanization was reducing the need for laborers. White Democrats had tried to restrict black voting; other southern states had excluded blacks from the political process. Many African Americans left rural Robertson County and other parts of Tennessee in theGreat Migration to northern and midwestern cities for employment and social freedom. Combined with the later in-migration of whites to the county, by the early 21st century, African Americans comprised less than 10 percent of the county population. They live chiefly in its larger towns.
According to theU.S. Census Bureau, the county has a total area of 476 square miles (1,230 km2), of which 476 square miles (1,230 km2) is land and 0.2 square miles (0.52 km2) (0.04%) is water.[4]
Unlike most of Tennessee, a sizable part of northern Robertson County is outside of theSun Belt due to a past error surveying the northern border ofMiddle andEast Tennessee. Downtown Springfield in particular is north of the Sun Belt.[5] The Sun Belt is defined by the Kinder Institute as being south of36°30'N latitude, which was intended to be the northern border of Tennessee and is the actual northern border ofWest Tennessee.[6]
