Hundreds of white nationalists – and those who oppose them -- were expected for a “Unite the Right” rally in Charlottesville, Virginia, on Saturday after a federal judge’s ruling Friday cleared the way for the event.

The judge’s ruling sparked a pre-rally march Friday night on the University of Virginia campus, resulting in clashes between marchers, protesters and police.

The unrest prompted Virginia Gov. Terry McAuliffe, a Democrat, to place National Guard members on standby, and encourage Virginians to stay away from Saturday’s event.

“Men and women from state and local agencies will be in Charlottesville [on Saturday] to keep the public safe,” McAuliffe said in a statement, “and their job will be made easier if Virginians, no matter how well-meaning, elect to stay away from the areas where this rally will take place.”

On Friday night, marchers holding tiki torches and chanting “White lives matter!” in front of a statue of university founder Thomas Jefferson were confronted by protesters, the Washington Post reported.

After fights broke out, police dispersed the crowd, claiming it was an unlawful assembly, Richmond’s WTRV-TV reported.

Saturday’s event is scheduled for Emancipation Park after U.S. District Judge Glen Conrad issued a preliminary injunction in a lawsuit that right-wing blogger and rally organizer Jason Kessler filed against the city of Charlottesville.

Kessler wants to protest Charlottesville’s decision to remove a statue of Confederate Gen. Robert E. Lee from Emancipation Park. He sued the city over free speech violations after the officials ordered the rally moved from Emancipation Park to a larger venue because of safety concerns.

In a statement, the city said it would honor the judge’s decision. Kessler is being represented in his case by the Rutherford Institute and the American Civil Liberties Union of Virginia.
