The "Three Musketeers" was the nickname given to three liberal members during the 1932–37 terms of the United States Supreme Court, who generally supported the New Deal agenda of President Franklin Delano Roosevelt.
[1] They were opposed by the "Four Horsemen", consisting of Justices James Clark McReynolds, George Sutherland, Willis Van Devanter, and Pierce Butler.
[2] Although the "Three Musketeers" were a bipartisan group, with Stone being a Republican, they were drawn together by their shared views on New Deal policies.
[4] Within a year, Van Devanter and Sutherland retired and were replaced by Hugo Black and Stanley Reed, strong New Dealers, ending the Four Horsemen's sway.
They often convinced the swing voters, Charles Evans Hughes and Owen Roberts, to vote for New Deal policies.
