Dyer introduced a revised version of the bill in the House of Representatives in 1921. Due to "insistent country-wide demand", it passed on January 22, 1922. The first such federal legislation to gain House passage in the twentieth century, it would have enabled the federal government to prosecute the crime. Southern authorities seldom did so. In the South, most blacks had been disfranchised from 1890 to 1911 by constitutional changes and discriminatory legislation after southern Democrats regained power in the state legislatures. Unable to vote, blacks were disqualified from serving on juries or holding any political office; they had virtually no political power within the official system. In the few cases that came to trial, all-white juries generally never convicted a white man of lynching a black.
