The British monarchy, one of the world’s oldest and most traditional institutions, follows strict rules to determine who ascends the throne in the event of a monarch’s death, abdication, or incapacity. With Charles III taking the crown in September 2022 after the passing of his mother, Queen Elizabeth II, attention has shifted to the line of succession that ensures the Crown’s continuity. In 2025, this system remains in focus, particularly amid speculation about the king’s health following his cancer diagnosis in February 2024. The succession framework, governed by historical laws and modern updates like the Succession to the Crown Act of 2013, establishes a clear order prioritizing Charles III’s direct descendants, starting with Prince William, his eldest son.
Charles III, now 76 years old, assumed the throne after decades as Prince of Wales, becoming the oldest monarch to begin a reign in British history. His official coronation, held in May 2023 at Westminster Abbey, marked a new chapter for the British royal family, defined by challenges such as modernizing the institution and maintaining its relevance in a rapidly changing world. The line of succession, which dictates the next in line for the throne, reflects not only family ties but also legislative adaptations that eliminated outdated male-preference primogeniture, ensuring gender equality among descendants.
Public interest in the succession has surged in recent months, driven by events like Charles III’s gradual return to public duties post-treatment and the growing visibility of his heir, Prince William. With a history spanning centuries, the British succession process is a well-established mechanism that continues to captivate and spark discussions about the monarchy’s future.
Who leads the line for the British throne
Prince William, the eldest son of Charles III and Princess Diana, holds the first position in the line of succession. Born on June 21, 1982, he became Prince of Wales after his father’s ascension, taking on a central role in representing the Crown. Married to Catherine Middleton, known as Kate, since 2011, William has distinguished himself in official engagements and humanitarian causes, preparing for a potential reign.
At 42 years old, William is already a prominent figure in the royal family, with military experience and a public profile that balances tradition with modernity. His status as the direct heir was reinforced in 2025 when he ramped up his schedule, joining his father in commitments like the January visit to Auschwitz, marking 80 years since the Nazi concentration camp’s liberation. Charles III’s health, though stable according to official statements, keeps the spotlight on a transition that could unfold in the coming years.
William is also the father of three children, who occupy the subsequent positions in the succession line, securing the dynasty’s future. His preparation for the throne is viewed as an ongoing process, with a focus on issues like sustainability and mental health, causes he has championed throughout his career.
The young heirs to the royal legacy
Following William, his children with Kate Middleton form the next generation of potential monarchs. Prince George, born on July 22, 2013, is second in line. At 11 years old in 2025, he already participates in public events alongside his parents, such as official visits and traditional ceremonies, signaling the early stages of his training as a future king. George is often compared to his father in childhood, when William held the same position during Elizabeth II’s reign.
Princess Charlotte, born on May 2, 2015, follows as third in line. At 9 years old, she benefits directly from the Succession to the Crown Act of 2013, which abolished male primogeniture, ensuring her place isn’t overtaken by her younger brother. Charlotte has appeared in royal engagements, like the Trooping the Colour, showing her growing role within the family.
The youngest, Prince Louis, born on April 23, 2018, holds the fourth spot. At 6 years old, he is still in an early phase of public exposure but draws attention during family events. These three siblings represent the immediate future of the monarchy, with an education carefully designed to uphold the Crown’s values while adapting to contemporary demands.
Prince Harry and his distance from the throne
Despite being Charles III’s second son, Prince Harry ranks fifth in the line of succession in 2025. Born on September 15, 1984, he stepped away from royal duties in 2020, choosing to leave the United Kingdom and settle in the United States with his wife, Meghan Markle, and their children. This decision, though controversial, did not alter his place in the succession order, which is determined by birth and regulated by the British Parliament.
Harry, now 40, maintains a distant relationship with the royal family, but his position in the line underscores the system’s rigidity. His children with Meghan—Archie Harrison, born on May 6, 2019, and Lilibet Diana, born on June 4, 2021—rank sixth and seventh, respectively. Archie, age 5, and Lilibet, age 3, gained prince and princess titles when Charles III ascended, but they lead a private life in California, far from the royal spotlight.
Harry and his children’s inclusion in the succession highlights that personal rifts don’t disrupt the legal framework. However, their chances of ascending the throne remain slim, given the number of heirs ahead of them.
A look at the full succession order
The British line of succession extends beyond Charles III’s direct descendants, encompassing other royal family members. After Archie and Lilibet, eighth place goes to Prince Andrew, Elizabeth II’s second son, born on February 19, 1960. At 65 in 2025, he stepped back from royal duties in 2019 due to his ties to Jeffrey Epstein but retains his succession rank.
Andrew’s daughters with Sarah Ferguson, Beatrice and Eugenie, follow in the line. Beatrice, born on August 8, 1988, is ninth, while Eugenie, born on March 31, 1990, is tenth. Both have their own families, with Beatrice welcoming her second daughter, Athena Elizabeth Rose, in 2025, adding more names to the extensive list of successors.
Here’s a summary of the top 10 in the line of succession in 2025:
Prince William, Prince of Wales;Prince George of Wales;Princess Charlotte of Wales;Prince Louis of Wales;Prince Harry, Duke of Sussex;Prince Archie Harrison Mountbatten-Windsor;Princess Lilibet Diana Mountbatten-Windsor;Prince Andrew, Duke of York;Princess Beatrice;Princess Eugenie.
This order may shift with births, marriages, or deaths, but it follows a strict logic based on descent and legislation.
How succession happens in practice
The succession process in the United Kingdom is automatic and immediate. When a monarch dies or abdicates, the next in line assumes the throne without delay, a principle rooted in the Act of Settlement of 1701. Following Elizabeth II’s death on September 8, 2022, Charles III ascended the same day, with his formal coronation occurring in May 2023.
If Charles III were to pass away or abdicate, William would become king instantly, taking the title William V. The coronation, however, requires parliamentary approval and a privy council, a ceremony that could take months to arrange. In cases of temporary incapacity, such as serious illness, the Regency Act of 1937 allows for a regent or counselors of state to assume duties on the monarch’s behalf.
Recent events, like Charles III’s October 2024 visit to Australia, where he faced republican protests, highlight the monarchy’s challenges, yet the succession system remains steadfast. William’s eventual ascension, whenever it occurs, will mark a significant moment in British history.
