Robert Browning was an English poet and playwright whose mastery of the dramatic monologue made him one of the foremost Victorian poets. His poems are known for their irony, characterization, dark humour, social commentary, historical settings, and challenging vocabulary and syntax. When Browning died in 1889, he was regarded as a sage and philosopher-poet who through his writing had made contributions to Victorian social and political discourse. Unusually for a poet, societies for the study of his work were founded while he was still alive. Such Browning Societies remained common in Britain and the United States until the early 20th century.
