From the Act of Union on 1 January 1801, until 6 December 1922, the island of Ireland was part of the United Kingdom of Great Britain and Ireland. During the Great Famine, from 1845 to 1849, the island's population of over 8 million fell by 30%.

This set the pattern of emigration for the century to come, resulting in a constant population decline up to the 1960s.
