Writers of the Romantic period were very unhappy about their lives and the state that the world around them was in. They wanted to escape their hometowns and people they know so as to find inner peace and places where they could be themselves without being judges, as well as places where they could write and express themselves freely. The effects that this had on literature were numerous: they often wrote about distant and mysterious parts of the world where their heroes could live their lives freely, their works were very emotional and full of melancholia for they all felt the pain of the whole world, their protagonists sought to find peace in nature, etc. Hope some of this helps. :)
