What period of time were the pre raphaelites working

The Pre-Raphaelite Brotherhood (later known as the Pre-Raphaelites) was a group of English painters, poets, and critics, founded in 1848 by William Holman Hunt, John Everett Millais and Dante Gabriel Rossetti. The three founders were joined by William Michael Rossetti, James Collinson, Frederic George Stephens and Thomas Woolner to form the seven-member "brotherhood". Their principles were shared by other artists, including Marie Spartali Stillman and Ford Madox Brown.
