The Uranians were a late-19th-century and early-20th-century clandestine group of up to several dozen male homosexual poets and prose writers who principally wrote on the subject of the love of (or by) adolescent boys. In a strict definition they were an English literary and cultural movement; in a broader definition there were also American Uranians. The movement reached its peak between the late 1880s and mid 1890s, but has been regarded as stretching between 1858, when William Johnson Cory's poetry collection Ionica appeared, and 1930, the year of publication of Samuel Elsworth Cottam's Cameos of Boyhood and Other Poems and of E. E. Bradford's last collection, Boyhood.
