William Blake would also be a great choice. Depending upon what your topic is, you could examine his life stages at the times when he wrote his "Songs of Innocence" and "Songs of Experience."
A lesser known and more unusual British poetic favorite of mine is Edward Field. He wrote a series of poems based on characters from monster movies of the 1930s that are terrific (including Frankenstein and The Cat Woman, among others). He manages to capture the eerie feel of the old B&W cinema while putting his own original touch to the poetry. Highly recommended.
If I were writing about a British poet I would choose Lewis Carroll. He was born in 1832 in Cheshire. He wrote poems such as Jabberwocky, The Aged Aged Man, and All in the Golden Afternoon. He wrote many other poems as well. Lewis Carroll also wrote Alice in Wonderland and Through the Looking Glass which are his most famous writings. What is unique about Lewis Carroll is that he liked to speculate on what makes sense and what is nonsense.
What is very interesting about Lewis Carroll is his life. He has been criticized for having a liking for children, especially girls. He also liked to photograph children. It is believed that this was all very innocent and people read into it too much. He also had older female friends whom he spent a great deal of time with.
Samuel Coleridge appeals me most .He wrote very view poems , such as , The Rime Of The Ancient Mariner , Christabel , and , Kublai Khan . All these poems belong to the province of super natural poetry .Coleridge is the first man in the British literature who could establish in his poems the conflict between experience and reasoning .His own phrase , "Willing suspension of disbelief", opens the vistas of new provinces in the realm of imaginations .He employs in his poems the essence of secondary imagination . Coleridge's originality has ever remained un-questioned .Himself he was a fellow brother of Wordsworth , but he was a true critic of Wordsworth's poems and theories related to Wordsworth's poetic works . Romanticism with Coleridge turns to true mysticism .He is a poet of the poets .
