Virginia on Wednesday became the first southern US state to abolish the death penalty.
Democratic Governor Ralph Northam signed a bill outlawing capital punishment in the state, saying it was "the moral thing to do."
Virginia is the 23rd US state to abolish the death penalty and the first of the states that made up the Confederacy during the 1861-65 US Civil War to do so.
Virginia has carried out more executions -- nearly 1,400 -- than any other of the 50 US states since its founding as a colony in the early 1600s.
Northam signed the bill ending the death penalty at the Greensville Correctional Center in Jarratt, Virginia, which houses the state's execution chamber.
"Signing this new law is the right thing to do," Northam said. "It is the moral thing to do to end the death penalty in the Commonwealth of Virginia."
"Virginia's history -- we have much to be proud of -- but not the history of capital punishment," he added.
Northam described the use of the death penalty in Virginia as "fundamentally flawed" and racially biased.
"We know that the system doesn't always get it right," he said. "We can't give out the ultimate punishment without being 100 percent sure that we're right."
"It is not fair," he added. "It is applied differently based on who you are."
Northam said that in the 20th century, 296 of the 377 defendants executed in Virginia for murder were Black.
The Virginia House of Delegates voted 57-41 last month to end capital punishment, two days after the state Senate approved a similar bill.
Virginia has conducted the second-most executions after Texas since the US Supreme Court reinstated the death penalty in 1976.
The state housed the capital of the pro-slavery South during the Civil War and was also the site of numerous lynchings of African Americans.
The death penalty has now been abolished in 23 states, while three others -- California, Oregon and Pennsylvania -- have observed a moratorium on its use.
Overall, US states carried out seven executions last year, with many opting to suspend the use of capital punishment because of the Covid-19 pandemic.
At the same time, former president Donald Trump's administration resumed federal executions and put 13 federal inmates to death between July 2020 and his departure from the White House in January.
Trump's successor, Joe Biden, has pledged to abolish the federal death penalty.
