How romantic poetry started?

Lines Written a Few Miles above Tintern Abbey is a poem by William Wordsworth. The title, Lines Written a Few Miles above Tintern Abbey, on Revisiting the Banks of the Wye during a Tour, July 13, 1798, is often abbreviated simply to Tintern Abbey, although that building does not appear within the poem. It was written by Wordsworth after a walking tour with his sister in this section of the Welsh Borders. The description of his encounters with the countryside on the banks of the River Wye grows into an outline of his general philosophy. There has been considerable debate about why evidence of the human presence in the landscape has been downplayed and in what way the poem fits within the 18th-century loco-descriptive genre.

Romantic poetry is the poetry of the Romantic era, an artistic, literary, musical and intellectual movement that originated in Europe towards the end of the 18th century. It involved a reaction against prevailing Enlightenment ideas of the 18th century, and lasted approximately from 1800 to 1850.
