A comprehensive political history of lesbianism in the 20th century, this work looks at: lesbians and the suffrage movement; lesbians and the First World War; Radclyffe Hall and "The Well of Loneliness" trial; lesbian life in the cosmopolitan 1930s; lesbian participation in the Second World War effort; lesbians in the 1950s; Esme Langley and "Arena Three"; and lesbian politics since the 1970s. In her discussion of the agenda and framework of lesbian political activism since 1900, Hamer documents the emergence of lesbian, feminist (and gay) political identities and sheds light on the complex relationships and interaction between these groups.
