The British parliament's Dependency of Ireland on Great Britain Act 1719 noted that the Irish House of Lords had recently "assumed to themselves a Power and Jurisdiction to examine, correct and amend" judgements of the Irish courts and declared that as the Kingdom of Ireland was subordinate to and dependent upon the British crown, the King, through the Parliament of Great Britain, had "full power and authority to make laws and statutes of sufficient validity to bind the Kingdom and people of Ireland".
The same year, the Irish constitution of 1782 produced a period of legislative freedom.
Legislative power was vested in the Parliament of Great Britain, which replaced both the Parliament of England and the Parliament of Scotland.
In practice it was a continuation of the English parliament, sitting at the same location in Westminster, expanded to include representation from Scotland.
However, the Irish Rebellion of 1798, which sought to end the subordination and dependency upon the British crown and establish a republic, was one of the factors that led to the formation of the United Kingdom of Great Britain and Ireland in 1801.
The deeper political integration of her kingdoms was a key policy of Queen Anne, the last Stuart monarch of England and Scotland and the first monarch of Great Britain.
The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about the "Union of the Crowns".
Also after the accession of King George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover.
The kingdoms of England and Scotland, both in existence from the 9th century (with England incorporating Wales in the 16th century), were separate states until 1707.However, they had come into a personal union in 1603, when James VI of Scotland became king of England under the name of James I.This Union of the Crowns under the House of Stuart meant that the whole of the island of Great Britain was now ruled by a single monarch, who by virtue of holding the English crown also ruled over the Kingdom of Ireland.The Union of 1707 provided for a Protestant-only succession to the throne in accordance with the English Act of Settlement of 1701; rather than Scotland's Act of Security of 1704, which ceased to have effect.The Act of Settlement required that the heir to the English throne be a descendant of the Electress Sophia of Hanover and not be a Catholic; this brought about the Hanoverian succession of George I in 1714.
