The Legitimation League was a British advocacy organisation founded in Leeds in 1893. It campaigned for the legitimation of illegitimate children and was later associated with free love and sexual reform. Its journal, The Adult, was published from 1897 to 1899.
The association was founded in Leeds in 1893 by a group of individualist anarchists associated with Benjamin Tucker and his magazine Liberty. Founding members included John Badcock, Joseph Hiam Levy, Greevz Fisher, Wordsworth Donisthorpe, Gladys Dawson, and Oswald Dawson. Advocates associated with the organisation included the poet and socialist Edward Carpenter and the sexologist and social reformer Havelock Ellis.
In 1897, the League moved its headquarters to London, where its meetings drew larger audiences. In the same year, the anarchist and women's rights activist Lillian Harman became president of the League. Karen Hunt writes that the League's original focus was the legitimacy and equality of children born outside church- or state-sanctioned unions, but that sexual liberation later became its main aim. At this time, Donisthorpe, who had served as president since 1893, and Fisher, who had served as vice-president, left the association.
The League's journal, The Adult, was published from 1897 to 1899, with the subtitles "A Journal for the Advancement of Freedom in Sexual Relationships" and "A Crusade Against Sex-Enslavement". Harman wrote several articles for the journal. It was originally edited by the League's secretary George Bedborough, whose wife Louie was treasurer, before his arrest in 1898 for selling a copy of Havelock Ellis's Studies in the Psychology of Sex Vol. 2.
According to Hunt, the League had been under surveillance by Scotland Yard as a suspected anarchist organisation, and Bedborough's arrest was used against it. After pleading guilty to an obscenity charge, Bedborough agreed not to remain associated with the League. Henry Seymour replaced Bedborough as editor until the journal's last issue in March 1899.
