History of Dinwiddie County

The first people to live in this area were Paleo-Indians. This was before 8000 BC. They were likely nomadic hunter-gatherers, meaning they moved around to hunt animals and gather food. Old stone tools have been found in fields across the county. When Europeans first arrived, Native American tribes lived here.
Dinwiddie County was officially formed on May 1, 1752. It was created from a part of Prince George County. The county got its name from Robert Dinwiddie. He was the Lieutenant Governor of Virginia from 1751 to 1758. People from the county formed groups of soldiers to fight in the American Revolution.
Dinwiddie County is also the birthplace of some important people. Elizabeth (Burwell) Hobbs Keckly was born here. She was a free Black dressmaker. She made clothes for the wives of two presidents: Mrs. Jefferson Davis and later Mary Todd Lincoln. Thomas Day was another famous person from Dinwiddie. He became a well-known free Black cabinetmaker in North Carolina. Dr. Thomas Stewart, who might have been America's first free Black country doctor in the 1700s, also came from here.
During the American Civil War, several battles took place in Dinwiddie County. One important battle was the Battle of Lewis's Farm. It happened on March 29, 1865. This was part of a plan by Union General Ulysses S. Grant. He wanted to cut off the last supply line for Confederate General Robert E. Lee's army. Union soldiers fought against Confederate soldiers. After some intense fighting, the Union troops dug in nearby. The Confederates then moved back to their lines. Four days later, the Union army cut the railway line. This happened after they won the Battle of Five Forks on April 1, 1865.
The Dinwiddie County Historical Society is now located in the old Dinwiddie County Court House.
