Anne became the first occupant of the unified British throne, and in line with Article 22 of the Treaty of Union, Scotland sent 45 Members to join all of the existing members of the Parliament of England in the new House of Commons of Great Britain.
Scottish elites retained power, and Scotland kept its legal and educational systems, as well as its established Presbyterian Church.
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.
It did not include Ireland, which remained a separate realm.
The unitary state was governed by a single parliament and government that was based in Westminster.
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.Scotland continued to have its own excellent universities, and with the strong intellectual community, especially in Edinburgh, The Scottish Enlightenment had a major impact on British, American and European thinking.As a result of Poynings' Law of 1495, the Parliament of Ireland was subordinate to the Parliament of England, and after 1707 to the Parliament of Great Britain.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.
