Colonial Era Poetry-
Poetry at this time was primarily metaphysical and devotional. Everything still strongly resembled English poetry, using their poetic modes and methods. The three most important poets were Puritans- Anne Bradstreet, Edward Taylor, and Michael Wigglesworth. Bradstreet ranks as the author of the first book of American poetry: "The Tenth Muse, Lately Sprung up in America."
18th Century Poetry-
The 18th century saw an increasing emphasis on America itself as a fit subject matter for its poets. The development of poetry in the colonies mirrored the development of the colonies themselves. As the colonists became more confident, their poetry reflected their drive toward independence. There weren't any extremely significant or influential poets at this time.
