Kemper County is a county located on the central eastern border of the U.S. state of Mississippi. As of the 2010 census, the population was 10,456.  Its county seat is De Kalb.  The county is named in honor of Reuben Kemper. 
The county is part of the Meridian, MS Micropolitan Statistical Area. In 2010 the Mississippi Public Service Commission approved construction of the Kemper Project, designed to use "clean coal" to produce electricity for 23 counties in the eastern part of the state. As of February 2017 [update], it was not completed and had cost overruns. It is designed as a model project to use gasification and carbon-capture technologies at this scale. 
In this county the land was developed in the 19th century by white planters for cotton cultivation, based on the labor of enslaved African Americans. It continues to be largely rural. After the American Civil War and Reconstruction, racial violence increased as whites struggled to regain power over the majority population of freedmen. In the period from 1877 to 1950, Kemper County had 24 documented lynchings of African Americans, third to Hinds and Leflore counties, which had 29 and 48, respectively.  This form of racial terrorism was at its height in the decades around the turn of the 20th century,  which followed the state's disenfranchisement of most blacks in 1890 through creating barriers to voter registration. In 1890, blacks made up the majority of the county' population: 10,084 blacks to 7,845 whites. 
Beginning in late December 1906, there were several days of racial terror in the county. After violent incidents on the railroad between conductors and black passengers, whites attacked blacks at the rural towns of Wahalak and Scooba; by December 27, a total of 13 blacks had been killed in rioting.   The events started with a physical confrontation between a conductor and an African-American man on a Mobile & Ohio Railroad train. The conductor was cut, and he fatally shot two black men. George Simpson, another African American thought to be involved, escaped from the train. When captured in Wahalak by a posse, he killed a white constable and was quickly lynched by the other whites. 
As reported by The New York Times,
Not satisfied with the punishment of this man, the whites immediately set out to strike terror into the negroes, who had been getting defiant of late. They found two sons of Simpson and lynched them, filling their bodies with bullets. Two other negroes who had behaved defiantly were treated in similar fashion. 
Whites worried about blacks gathering to take revenge at Wahalak, where they had already been abused by lynchings, authorities called for state militia. Their commanding officer took his troops away from Wahalak while there was still unrest because he felt they were not being treated properly. 
By the end of the day on December 26, white men in Scooba had killed another five black men. The county sheriff arrested several whites for these murders, and called for the state militia to go to Scooba. "All the men killed at Scooba today are said to be innocent of any crime, having been shot down merely as a matter of revenge by the rough whites."  There had been a conflict on another train, in which a black man mortally shot a conductor, George Harrison. The yardmaster shot and killed the African American. The rioting by whites in Scooba started after Harrison died.  Governor James K. Vardaman went to Scooba with militia to establish control. He left a force of 20 there commanded by Adjutant General Fridge and returned to the state capital on the evening of December 27. That day the body of another murdered African-American man was found in the woods, bringing the total killed in Scooba to six. 
In 1934, three African-American suspects in Kemper County were repeatedly whipped in order to force them to confess to murder. In Brown v. Mississippi (1936), the U.S. Supreme Court unanimously ruled such forced confessions violated the Due Process Clause of the Fourteenth Amendment, and were inadmissible at trial. 
The peak of population in the county was in 1930. Mechanization of agriculture decreased the need for farm labor. From 1940 to 1970, the population declined markedly, as may be seen on the table below, as people moved to other areas for work. This was also the period of the second wave of the Great Migration of 5 million African Americans out of the South to the North and to the West Coast, where the defense industry had many jobs, beginning during World War II.

Kemper County is within the service area of the East Mississippi Community College system.  The main campus of EMCC, including the college system's administrative headquarters, is in the Scooba Campus in Scooba. 
The county is governed by a five-member elected Board of Supervisors, who are elected from single-member districts. The County Sheriff, Chancery Clerk, Circuit Clerk, and Tax Assessor are also elected to office.
Kemper County generally votes for candidates of the Democratic Party; the Republican presidential nominee has won it only four times in the past century.
In 2010, the Mississippi Public Service Commission approved the construction of a lignite coal plant in Kemper County to be financed by electricity customers in twenty-three southeastern Mississippi counties being served by Mississippi Power Company. It is designed as a model project to use gasification and carbon-capture technologies at this scale. 
The plant was strongly opposed by former Republican State Chairman Clarke Reed of Greenville, who favored a less-expensive natural gas-fueled plant. Reed called the project "... a horrible thing." He said it would be a political issue that could be used against Republicans for years. 
The Kemper Project was scheduled to open in the third quarter of 2016, more than two years behind schedule. Its cost increased to $6.6 billion—three times original cost estimate.   As of February 2017 [update], the project was still not in service, and the cost had increased to $7.1 billion.
