Footnotes - The Irish Free State seceded from the United Kingdom in 1922 as a result of the Anglo-Irish Treaty, but this fact was not reflected in the long-form name of United Kingdom until Royal and Parliamentary Titles Act in 1927. The current British state, the United Kingdom of Great Britain and Northern Ireland, is universally accepted to be a direct continuation of the United Kingdom of Great Britain and Ireland, and should not be imagined to be a break from it or a new state formed after it. The Royal motto used in Scotland was Nemo Me Impune Lacessit (Latin for "No-one provokes me with impunity"). In addition to English (official status established by precedent), Irish, Scottish Gaelic, and Welsh were spoken regionally.
