The Line of Succession to the British Throne, Explained
Who is next in line, how the order is decided, and the modern rule change that put sons and daughters on an equal footing.
Every so often a royal birth or a new reign sends people reaching for the same question: who, exactly, is next in line? The line of succession is one of the oldest mechanisms in British public life, and, thanks to a recent reform, one that has quietly become a good deal fairer.
A question older than Parliament
Long before there were Acts of Parliament to settle the matter, the English crown passed according to custom, military force, and the sometimes lethal logic of dynastic politics. Medieval succession operated on a broad principle of hereditary right: the throne descended through a monarch’s children and then to wider kin. But the principle was routinely challenged by competing claimants who believed their bloodline entitled them to more than they held.
The Wars of the Roses, fought between the Houses of Lancaster and York through much of the fifteenth century, stand as the starkest reminder of what happens when succession is contested. Decades of conflict, shifting allegiances, and the deaths of two kings in battle arose directly from the question of which branch of the Plantagenet family held the better claim. The Tudor settlement that followed (Henry VII united the rival roses through his marriage to Elizabeth of York in 1486) established a dynasty and, with it, the principle that Parliament could confirm and consolidate the succession rather than leave it purely to hereditary chance.
The Act of Settlement 1701
The most important succession statute before the modern era is the Act of Settlement 1701. Passed at a moment of genuine dynastic anxiety (King William III had no surviving children, and the Protestant line of succession was alarmingly thin), the Act directed that, should William and his likely successor Queen Anne die without heirs, the crown would pass to Sophia, Electress of Hanover, and “the heirs of her body being Protestants.”
The requirement that the sovereign be in communion with the Church of England, and that the crown could not pass to a Roman Catholic, became fixed constitutional law. That provision remains in place today, though the Succession to the Crown Act 2013 removed the rule barring those who married Catholics from the line of succession: a measure long overdue. The Act of Settlement also prohibited the sovereign from marrying a Catholic, a restriction that was likewise relaxed by the 2013 legislation.
The Act was not merely a matter of religion. It embedded the principle that Parliament, not the sovereign alone, had the authority to determine who sat on the throne, a principle with roots in the Glorious Revolution of 1688 and the Bill of Rights of 1689.
The path to 2013: earlier succession laws
Between 1701 and 2013, a series of further statutes shaped the succession in important ways. The Act of Union 1707 brought Scotland into the same line of succession as England, creating the Kingdom of Great Britain. The His Majesty’s Declaration of Abdication Act 1936 made law the exceptional circumstances under which a monarch could remove themselves from the throne, and, with them, their descendants. The Royal Marriages Act 1772, long criticised as cumbersome, required members of the royal family to seek the sovereign’s consent before marrying, on pain of the marriage being void; the Succession to the Crown Act 2013 replaced it with a narrower requirement applying only to the first six people in line.
Each adjustment reflected the constitutional reality that the Crown’s succession is ultimately a matter for Parliament, not a private family arrangement, however grand the family.
The Succession to the Crown Act 2013 in detail
The Succession to the Crown Act 2013 is the most significant reform to the rules of royal succession in three centuries. Its passage followed the Perth Agreement of October 2011, reached at a Commonwealth Heads of Government Meeting in Australia, at which the sixteen realms that share the British monarch as their head of state gave their consent to the proposed changes. The coordination required, separate legislation in each realm, was no small diplomatic undertaking, and the Marlborough House meeting of senior Commonwealth officials in the months that followed worked through the practicalities of synchronising the law across jurisdictions as varied as Canada, Australia, Jamaica, and New Zealand.
The centrepiece of the Act is the shift from male-preference primogeniture to absolute primogeniture for those born after 28 October 2011. Under the old rule, a younger son would leapfrog an elder daughter. Under absolute primogeniture, the eldest child inherits regardless of sex. The practical effect was immediately visible in the Cambridge family: Princess Charlotte, born in 2015, holds her place ahead of her younger brother, Prince Louis, and no future birth of a brother could displace her.
The Act also removed the automatic disqualification of those who married Catholics, and narrowed the royal marriages consent requirement to the six people closest to the throne.
Titles and their significance
Titles in the line of succession are not merely ceremonial labels; they carry constitutional and financial significance. The Prince of Wales is the title held by the heir apparent (traditionally the eldest son of the sovereign, now formally the eldest child), and it must be specifically conferred. It does not pass automatically at birth, a distinction that occasionally surprises those who assume it does.
The Duchy of Cornwall, by contrast, does pass automatically: the eldest son of the sovereign becomes Duke of Cornwall the moment the sovereign accedes, as Prince William did when King Charles III came to the throne in September 2022. The Duchy is a substantial estate generating significant income for its holder. Similarly, the Duchy of Lancaster is held by the sovereign personally and provides income to the Crown.
Further down the family, titles such as Duke of Sussex and Duke of York are granted by Letters Patent and do not pass to all children automatically. The question of which children of the next generation will hold royal titles, and which will not, is a matter that each reign tends to address in its own way.
The current line: who stands where
As of 2026, the top of the line of succession runs as follows:
- Prince William, Prince of Wales: King Charles III’s elder son
- Prince George of Wales: William’s eldest child
- Princess Charlotte of Wales: William’s second child
- Prince Louis of Wales: William’s youngest child
- Prince Harry, Duke of Sussex: King Charles III’s younger son
- Prince Archie of Sussex: Harry’s elder child
- Princess Lilibet of Sussex: Harry’s younger child
- Prince Andrew, Duke of York: King Charles III’s younger brother
- Princess Beatrice of York: Andrew’s elder daughter
- Sienna Mapelli Mozzi: Beatrice’s daughter
The line continues through Princess Eugenie, Princess Anne, and their descendants before moving to the wider family. Each new birth reshuffles the lower reaches of the order without affecting those above the new arrival.
Removed from the line: history’s hard cases
Circumstances under which an individual is removed from the line of succession are rare but historically resonant. For most of the past three centuries, conversion to Roman Catholicism was sufficient to place a person outside the succession entirely; the Act of Settlement made that automatic.
The most dramatic modern case is the Abdication of 1936. King Edward VIII signed the Instrument of Abdication on 10 December 1936, unwilling to give up his relationship with the American divorcée Wallis Simpson, and his descendants were formally excluded from the succession by the His Majesty’s Declaration of Abdication Act passed that same day. The Duke of Windsor, as Edward became, lived out his long life in France, and the question of his place in the order became moot. His decision reshaped the twentieth-century monarchy, placing his brother, the stammering, reluctant George VI, on the throne and, in time, putting Elizabeth II on the path to her remarkable seventy-year reign.
Today, renouncing the succession is not something that can be done casually, and no mechanism exists in current law for an individual simply to “opt out.” The Duke of Sussex’s decision to step back from royal duties in 2020 carried no legal consequence for his place in the line of succession.
Parliament and the Crown: a constitutional partnership
The relationship between Parliament and the Crown’s succession is one of the defining features of Britain’s unwritten constitution. Parliament does not merely rubber-stamp the hereditary line; it has the authority, demonstrated repeatedly across the centuries, to redirect it. The Glorious Revolution, the Act of Settlement, the Abdication Act, and the reforms of 2013 all speak to that sovereign legislative power.
At the same time, convention plays an enormous role. The Crown Acts do not confer legitimacy purely through statutory language; they work because they command the assent of the political nation: Parliament, the Church of England, the Commonwealth realms, and, in a broader sense, public opinion. When Edward VIII abdicated, the crisis was resolved not only by legislation but by the swift alignment of political, ecclesiastical, and popular sentiment around his brother.
Why succession still matters
In an era of democratic governance, the significance of a hereditary succession may not be immediately obvious. Its importance, however, is constitutional rather than political. A settled, unambiguous line of succession means that no moment of royal transition, however unexpected, creates a vacuum of authority. The principle that the King never dies, that “the King is dead, long live the King” operates as legal doctrine rather than metaphor, ensures continuity of the state in a way that no elective system can quite replicate.
For the millions who follow the royal family with genuine affection, the line of succession is also a story: of births and marriages, of the slow shifting of generations, of a family whose private milestones become matters of public record and public celebration. Each new name added to the line, each Prince George or Princess Charlotte, is a small reminder that the institution is not static but living, shaped anew by every family that inhabits it.
The line of succession is, in the end, a legal mechanism serving a human purpose: the orderly, peaceful transfer of an ancient office. That Britain has managed it, with one dramatic exception in 1936, for more than three centuries without constitutional crisis is itself no small achievement.

Frequently asked questions
Who is currently first in line to the British throne?
Prince William, the Prince of Wales, is first in line to the throne. He is the elder son of King Charles III, who has reigned since September 2022.
What is the Succession to the Crown Act 2013 and what did it change?
The Succession to the Crown Act 2013 introduced absolute primogeniture for those born after 28 October 2011, meaning the throne now passes to the eldest child regardless of sex. It also removed the automatic disqualification of those who married Roman Catholics and narrowed the royal marriages consent requirement to the six people closest to the throne.
Why does Princess Charlotte rank above Prince Louis even though he is a prince?
Under absolute primogeniture, introduced by the 2013 Act, the crown passes to the eldest child irrespective of gender. Princess Charlotte was born before Prince Louis, so she holds the higher position. Under the old male-preference rules, a younger son would have ranked above an elder daughter; that is no longer the case.
What is the Act of Settlement 1701 and is it still in force?
The Act of Settlement 1701 directed that the crown pass to Protestant heirs and required the sovereign to be in communion with the Church of England. Much of the Act remains in force, though the 2013 reforms removed the rule barring those who marry Catholics from the line of succession.
Can a member of the royal family renounce their place in the line of succession?
There is no legal mechanism in current British law for an individual simply to opt out of the succession. The Duke of Sussex’s decision to step back from royal duties carried no formal legal consequence for his position in the line.
What happened to Edward VIII’s descendants after the Abdication?
The His Majesty’s Declaration of Abdication Act 1936, passed on the same day Edward VIII signed the Instrument of Abdication, excluded Edward and his descendants from the succession. He had no children, so this provision never came into practical effect, but it established the principle that abdication carries hereditary consequences.
Do the Commonwealth realms follow the same line of succession?
Yes. The sixteen Commonwealth realms that share the British monarch as their head of state follow the same line of succession. Coordinating the changes introduced by the Succession to the Crown Act 2013 required each realm to pass its own corresponding legislation, a process helped along by the Perth Agreement of 2011 and subsequent discussions at Marlborough House.
How does the title “Prince of Wales” differ from other royal titles?
The title Prince of Wales is not automatic; it must be formally conferred by the sovereign. Other titles, such as Duke of Cornwall, do pass automatically to the heir apparent upon accession. The distinction matters constitutionally and financially: the Duchy of Cornwall is a significant landed estate whose income belongs to the holder as soon as they inherit the position.
