Protocols of the Elders of Zion, also called Protocols of the Learned Elders of Zion, a document that served as a pretext and rationale for anti-Semitism mainly in the early 20th century. The document purported to be a report of a series of 24 (in other versions, 27) meetings held at Basel, Switzerland, in 1897, at the time of the first Zionist congress. There Jews and Freemasons were said to have made plans to disrupt Christian civilization and erect a world state under their joint rule. Liberalism and socialism were to be the means of subverting Christendom; if subversion failed, all the capitals of Europe were to be sabotaged.
