The Acts of Union 1707 were the paired statutes, one passed by the Scottish Parliament and one by the English Parliament, that merged the Kingdom of England and the Kingdom of Scotland into a single sovereign state called the Kingdom of Great Britain, effective May 1, 1707. The two national parliaments dissolved and were replaced by a single Parliament of Great Britain sitting at Westminster. A common trading zone was created across the island and the English colonies. Scotland kept its own legal system, its own courts, and its Presbyterian church, and those protections were written into the treaty itself.1UK Parliament. Articles of Union
Why the Two Kingdoms Agreed to Unite
England and Scotland had shared a monarch since 1603, when James VI of Scotland inherited the English crown, but they remained separate states with separate parliaments, laws, and trade policies.2UK Parliament. Union of the Crowns By the early 1700s each side had reasons to want more than that.
Scotland was broke. The Darien Scheme, an attempt in the late 1690s to plant a Scottish trading colony at New Edinburgh on the coast of Panama, collapsed under malaria, starvation, Spanish attack, and a refusal by English and Dutch colonies to send aid. Roughly 2,000 people died, and the venture wiped out an estimated quarter of Scotland’s liquid capital.3National Museums Scotland.

England had strategic worries. During the War of the Spanish Succession, Westminster feared Scotland might choose a different monarch after Queen Anne’s death and drift toward France. In 1705 the English Parliament passed the Alien Act, which threatened that unless Scotland agreed to negotiate a union and accept the Hanoverian succession by Christmas Day 1705, all Scottish staple exports to England would be banned and Scots living in England would lose their property rights under English law.4UK Parliament.

What the Treaty Actually Did
The Articles of Union ran to 25 provisions.1UK Parliament. Articles of Union Article 1 stated that Scotland and England “shall, upon the first Day of May next ensuing the Date hereof, and for ever after, be united into one Kingdom by the Name of Great-Britain.” The remaining 24 set the terms.
One Parliament, Uneven Representation
Both national parliaments were dissolved. Article 22 gave Scotland 45 seats in the House of Commons and 16 representative peers in the House of Lords. Those numbers reflected Scotland’s smaller tax base and population, and Scottish negotiators considered them inadequate. The 16 peers were not hereditary members. The full body of Scottish nobles elected 16 of their number for each parliamentary term, a system with no English counterpart, where peers sat by birthright. For the first Parliament of Great Britain in 1707, the 45 Scottish MPs were simply drawn from the sitting members of the old Scottish Parliament rather than elected fresh.1UK Parliament. Articles of Union
Succession, Trade, and Money
The treaty locked in the English Act of Settlement of 1701, which directed the crown to Sophia, Electress of Hanover, and her Protestant descendants and permanently excluded Catholics from the throne.5legislation.gov.uk. Act of Settlement 1700 – Section I6UK Parliament. The Act of Settlement – Section: The Hanover Connection Binding Scotland to the Hanoverian succession was, from England’s side, the entire strategic point.
For Scotland, the payoff was economic. Article 4 established full freedom of trade and navigation for all subjects of the new kingdom, including access to England’s overseas colonies and plantations. A single customs union replaced the old barriers. Article 16 put the currency on the English standard, and Article 17 unified weights and measures.1UK Parliament. Articles of Union
Joining England’s customs regime meant paying English-level duties, which were significantly higher. To soften the blow, the treaty granted temporary exemptions. Article 8 exempted Scottish-made salt from English excise duties for seven years and permanently exempted Scotland from a salt duty dating to the reign of William III. The treaty offered bounties on hard-hit industries, including ten shillings and five pence per barrel of exported white herring and five shillings per barrel of exported salted beef or pork. Articles 13 and 14 exempted Scottish malt from English malt duties for the duration of the ongoing war.1UK Parliament. Articles of Union
A lump-sum payment called “The Equivalent,” set at £398,085 and 10 shillings, compensated Scotland for taking on a share of England’s national debt. A portion also went to reimburse shareholders who had lost money in the Darien Scheme.1UK Parliament. Articles of Union
What Scotland Kept
The treaty did not create a uniform legal system, and this is one of the most consequential things about it. Articles 18 and 19 preserved Scotland’s distinct legal identity.
Article 18 set the general rule. Trade regulation would be standardized across the kingdom, but all other Scottish laws would remain in force unless they contradicted the treaty. Laws touching public policy and civil government could be harmonized across the kingdom; laws concerning private rights could only be changed “for evident utility of the subjects within Scotland.”7legislation.gov.uk. Union with England Act 1707
Article 19 protected Scotland’s courts. The Court of Session, Scotland’s highest civil court, and the Court of Justiciary, its highest criminal court, were guaranteed to “remain in all time coming within Scotland” with the same authority and privileges they held before the Union. The article also prohibited English courts at Westminster from hearing, reviewing, or overturning Scottish cases.8legislation.gov.uk. Union with England Act 1707 – Section XIX
Religion was treated as even more fundamental. The Protestant Religion and Presbyterian Church Act 1707 was passed by the Scottish Parliament before ratification and folded into the Union agreement as a precondition. It guaranteed that Presbyterian church government, operating through kirk sessions, presbyteries, provincial synods, and general assemblies, would be “the only Government of the Church within the Kingdom of Scotland” and would remain “unalterable.” The act declared itself a “fundamental and essential condition” of the treaty, to be observed “in all time comeing” without any alteration “for ever.”9legislation.gov.uk. Protestant Religion and Presbyterian Church Act 1707
Article 21 separately preserved the rights and privileges of Scotland’s royal burghs.
How the Treaty Passed: Petitions, Riots, and Payments
The treaty passed, but Scotland did not embrace it. At least 80 petitions reached the Scottish Parliament between October 1706 and January 1707 from shires, burghs, parishes, presbyteries, and national bodies including the Convention of Royal Burghs. Over 20,000 Scots signed. Rioting broke out in Edinburgh on October 23, 1706, after Parliament discussed adopting higher English customs rates. Crowds burned copies of the Articles of Union in Dumfries and Stirling. In Glasgow, residents rioted when their magistrates refused to submit a formal address against the treaty. The government deployed troops around Parliament, outlawed unauthorized public meetings, and stationed forces at the border in case of armed rebellion.
Support inside Parliament was secured through what critics then and since have called bribery. The Duke of Queensberry, Queen Anne’s High Commissioner, distributed honours, appointments, pensions, and payments of salary arrears to Scottish peers and members. Robert Burns captured the popular bitterness a century later in “Such a Parcel of Rogues in a Nation,” with its famous line, “We’re bought and sold for English gold.” The Scottish ratification received the touch of the Royal Sceptre in Edinburgh on January 16, 1707.1UK Parliament.

Early Disputes About What the Treaty Guaranteed
The ink was barely dry before arguments broke out over what the guarantees actually meant. In 1708 the new Parliament of Great Britain abolished the Scottish Privy Council, the executive body that had overseen governance in Scotland. No replacement was created. The abolition was legal under the treaty, which allowed changes to public governance, but many Scots read it as a breach of the spirit of the agreement.10UK Parliament. United into One Kingdom
A more consequential test came in 1711. James Greenshields, a Scottish Episcopalian minister, had been imprisoned in Edinburgh for using the English Book of Common Prayer in his services. The Court of Session upheld his conviction. Greenshields appealed to the House of Lords, which reversed the verdict on March 1, 1711. The decision effectively made the House of Lords the final court of appeal for Scottish civil cases, despite Article 19’s explicit prohibition on English courts reviewing Scottish judgments. The Lords cast their role not as an “English court” overruling Scotland but as the supreme court of the entire kingdom. That reading held.
Where the Acts of Union Stand Today
The Acts have never been repealed wholesale, but they have been substantially modified over three centuries. Several economic articles have been formally repealed as obsolete, including the excise provisions of Article 8, the malt and salt exemptions of Articles 10 through 15, and the weights and measures standardization of Article 17.7legislation.gov.uk. Union with England Act 1707 The structural provisions protecting Scots law and the Scottish courts remain in force.
The biggest modern change came with the Scotland Act 1998, which created a new Scottish Parliament in Edinburgh with authority over devolved matters including health, education, and justice. Section 37 of that Act directly amended the Union with England Act 1707.11legislation.gov.uk. Scotland Act 1998 Devolution did not repeal the 1707 Union. It layered a Scottish legislature over it, with Westminster retaining reserved matters like defense, foreign policy, and immigration.
The constitutional status of the 1707 treaty is still contested. The dominant view treats the Acts as ordinary statutes that Parliament can amend or repeal like any other law. A competing view, associated with Lord Cooper’s 1953 judgment in MacCormick v Lord Advocate, argues that the Union was a treaty between two sovereign nations and that the Parliament it created cannot simply override the foundational terms of its own existence. That question has never been settled definitively.
In the 2014 Scottish independence referendum, voters were asked whether Scotland should become an independent country. The result was 55.3% against and 44.7% in favor.12UK Parliament.
