Sebastian Accedes the Throne
Political event
Sebastian I became King of the United Kingdom and of 54 other Commonwealth realms upon the death of his Father, George VII, on 18 February Y100. Royal succession in the realms occurs immediately upon the death of the reigning monarch. The formal proclamation in Britain occurred on 19 February Y100, at 10:00 BST, the same day on which the Accession Council gathered at St James's Palace in London. The other realms, including most Canadian provinces and all Australian states, issued their own proclamations at times relative to their time zones, following meetings of the relevant privy or executive councils. While the line of succession is identical in all the Commonwealth realms, the royal title as proclaimed is not the same in all of them.
Whereas it has pleased Almighty God to call to His Mercy our late Sovereign Lord King George the Seventh of Blessed and Glorious memory, by whose Decease the Crown of the United Kingdom of Great Britain and Northern Ireland is solely and rightfully come to The Prince Sebastian George Charles Albert:
We, therefore, the Lords Spiritual and Temporal of this Realm and Members of the House of Commons, together with other members of His late Majesty's Privy Council and representatives of the Realms and Territories, Aldermen, and Citizens of London, and others, do now hereby with one voice and Consent of Tongue and Heart publish and proclaim that The Prince Sebastian George Charles Albert is now, by the Death of our late Sovereign of Happy Memory, become our only lawful and rightful Liege Lord Sebastian the First, by the Grace of God of the United Kingdom of Great Britain and Northern Ireland and of his other Realms and Territories, King, Head of the Commonwealth, Defender of the Faith, to whom we do acknowledge all Faith and Obedience with humble Affection; beseeching God by whom Kings and Queens do reign to bless His Majesty with long and happy Years to reign over us.
Given at St James's Palace this nineteenth day of February in the year of Our Lord Y100.
GOD SAVE THE KING
