Liberty Hill Site

San Pedro, Los Angeles County · California
Erected by State Department of Parks and Recreation; San Pedro Bay Historical Society; and the American Labor Movement, 1998

In 1923 the Marine Transport Workers of the IWW struck the waterfront and stopped ninety ships, protesting wages, conditions, and the jailing of organizers under the state's criminal syndicalism law. Barred from public ground, strikers met on a private rise they named Liberty Hill. On May 15 Upton Sinclair stood up there and began reading the Bill of Rights aloud. Police arrested him before he finished and held him four days incommunicado. The strike was broken; the organizing it seeded came back in the 1930s.

What the plaque says

In 1923 the Marine Transport Industrial Workers Union 510, a branch of the Industrial Workers of the World (IWW), called a strike that immobilized 90 ships here in San Pedro. The Union protested low wages, bad working conditions, and imprisonment of union activists under California's criminal syndicalism law. Denied access to public property, strikers and supporters rallied here at this site they called "Liberty Hill." Writer Upton Sinclair was arrested for reading from the Bill of Rights to a large gathering. The strike failed but laid a foundation for success in the 1930s. The syndicalism law was ruled unconstitutional in 1968.
