Whereas in pursuance of His Majesty's most gracious recommendation to the two houses of parliament in Great Britain and Ireland respectively, to consider of such measures as might best tend to strengthen and consolidate the connexion between the two kingdoms, the two houses of the parliament of Great Britain and the two houses of the parliament of Ireland have severally agreed and resolved, that, in order to promote and secure the essential interests of Great Britain and Ireland, and to consolidate the strength, power, and resources of the British Empire, it will be advisable to concur in such measures as may best tend to unite the two kingdoms of Great Britain and Ireland into one kingdom, in such manner, and on such terms and conditions, as may be established by the acts of the respective parliaments of Great Britain and Ireland:

That it be the first article of the union of the kingdoms of Great Britain and Ireland, that the said kingdoms of Great Britain and Ireland shall, upon the first day of January which shall be in the year of our lord one thousand eight hundred and one, and for ever after, be united into one kingdom, by the name of the "United Kingdom of Great Britain and Ireland”; and that the royal stile and titles appertaining to the imperial crown of the said United Kingdom and its dependencies, and also the ensigns, armorial flags and banners thereof, shall be such as His Majesty, by his Royal Proclamation under the Great Seal of the United Kingdom, shall be pleased to appoint.
