  |  This article focuses on poetry written in English from the United        |
  |  Kingdom: England, Scotland, Wales, and Northern Ireland (and Ireland     |
  |  before 1922). However, though the whole of Ireland was politically part  |
  |  of the United Kingdom between January 1801 and December 1922, it is      |
  |  controversial to describe Irish literature as British.[citation needed]  |
  |  For some this includes works by authors from Northern Ireland. The       |
  |  article does not include poetry from other countries where the English   |
  |  language is spoken.                                                      |
