San Francisco demonstrators smashed the sculpture of Francis Scott Key, the author of the “Star-Spangled Banner” and a slave owner.

A group of 19th protesters lowered the monument at Golden Gate Park on Friday night after being heavily tagged with anti-slavery and anti-colonial graffiti.

They also tore his monument near the park to President Ulysses S. Grant.

Grant led the Union Army during the Civil War, but married a slave-owning family, and according to the American Civil War Museum, he became a slave briefly about a year before the war.

According to the Smithsonian, Key, who wrote the lyric “The land of freedom”, went to court to defend his right to use his own slaves.

About 400 protesters were in the park because the monuments were removed and not arrested, according to your local NBC affiliate.

The sculptures are among many dedicated to white men affiliated with slavery or the Confederation all over the country.

Shortly after the protesters smashed San Francisco monuments, the protesters in Washington, D.C., overthrew and burned only the Confederation statue of the country’s capital, General Albert Pike.

In Richmond, Virginia, protesters received training on the diversity of the city’s confederate statues. Earlier this month, the demonstrators lowered the monument to Jefferson Davis, the president of the Confederate States of America, which continued along the city’s storey Monument Avenue.

The most controversial Confederation statue in the street, the great monument of General Robert E. Lee, has become the protest gathering point in the city. Protesters also reflect Floyd’s face on his base.

Virginia Governor Ralph Northam has announced that he will pull down the 60-foot Lee statue, and has been temporarily blocked only by ongoing court orders.
