The City Council voted unanimously Monday to remove the monuments immediately, CNN affiliate WBAL reported.
By early Wednesday, video posted on social media showed cranes slowly lowering some of the monuments from their perches. Mayor Catherine Pugh told WBAL that some of the monuments will be sent to Confederate cemeteries.
The removals come as cities and states are considering taking down Confederate monuments following the clashes at Saturday’s rally in Charlottesville, Virginia, which left one anti-racism protester dead.
Statues in Lexington, Kentucky, are expected to be removed, while in Durham, North Carolina, a woman was arrested in the toppling of a Confederate statue during a protest Monday.
In New Orleans, the final Confederate statue in the city came down in May.
The memorials removed in Baltimore included the Roger B. Taney Monument, and a monument honoring Confederate generals Robert E. Lee and Thomas J. “Stonewall” Jackson, according to WBAL.
Taney, a Supreme Court chief justice, led the infamous Dred Scott decision a few years before the Civil War. It found that slaves were not citizens of the United States and therefore were not protected under the US Constitution.
The 13th and 14th amendments, which were adopted in 1865 and 1868, formally outlawed slavery and granted citizenship “to all persons born or naturalized in the United States,” which included former slaves.
The Southern Poverty Law Center last year cataloged 718 Confederate monuments and statues. It said about 300 of them are in Georgia, Virginia and North Carolina.
