Catherine, Princess of Wales, and the 700-Year History Behind Her Title

Catherine waited more than 11 years after her wedding to become Princess of Wales.

When she married Prince William on April 29, 2011, Queen Elizabeth II made him Duke of Cambridge. Catherine became Duchess of Cambridge. The couple built their public life under that title while raising Prince George, Princess Charlotte, and Prince Louis.

Everything changed after Queen Elizabeth II died on September 8, 2022. William became Duke of Cornwall because he was the King’s eldest living son and heir. One day later, King Charles III announced that William and Catherine would become Prince and Princess of Wales.

The announcement connected Catherine to a title with at least 725 years of English royal history and even older Welsh roots. It also placed her in a line of women whose lives reflected war, dynastic strategy, political influence, public scrutiny, and service.

The Title Did Not Pass Automatically

The distinction between William’s titles matters.

William became Duke of Cornwall automatically when his father became King. Prince of Wales works differently. The sovereign must grant or announce the title. Charles made that decision during his first address to the nation on September 9, 2022.

“With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations,” the King said.

Catherine holds her title through marriage. She was not born a princess, and Princess of Wales does not make her a constitutional ruler of Wales. Her formal style is Her Royal Highness The Princess of Wales.

The title also differs from Princess Royal. That honor may be granted by a monarch to a daughter. Princess Anne currently holds it.

The Story Began Before 1301

The phrase Prince of Wales existed before English kings adopted it for their heirs.

Welsh ruler Llywelyn ap Gruffudd used the title and received recognition under the Treaty of Montgomery in 1267. His wife, Eleanor de Montfort, appears in historical records as Princess of Wales. Their position belonged to an independent Welsh political order.

That order ended during Edward I’s conquest. Llywelyn died in December 1282, and his brother Dafydd was captured and executed in 1283.

Edward then built a network of castles and controlled towns across Wales. His son Edward of Caernarfon was born at Caernarfon Castle on April 25, 1284. In 1301, Edward I gave him the title Prince of Wales. A historical list of Welsh rulers and later Princes of Wales places the grant within the longer transition between native Welsh rule and the English royal tradition.

According to a widely repeated but disputed tradition, Edward was presented to Welsh nobles as a prince born in Wales who spoke no English. The appointment followed military conquest and would have carried a deeply insulting meaning for Welsh leaders who had lost political control.

That tension still shapes the title’s meaning. Some people see it as part of a shared British royal tradition. Others connect it directly to conquest and the loss of independent Welsh rule.

The First English Princess of Wales Arrived 60 Years Later

The male title entered English royal use in 1301, but the first wife of an English Prince of Wales appeared in 1361.

Joan of Kent gained the title when she married Edward of Woodstock, known as the Black Prince. Their son became Richard II at age 10 in 1377. Joan then helped defend the young King’s interests during a dangerous period.

Other holders followed, though the title often remained unused for decades or centuries.

Catherine of Aragon became Princess of Wales when she married Arthur, Prince of Wales, in 1501. Arthur died less than five months later. She later married his younger brother, Henry VIII, and became Queen. Historic Royal Palaces records her brief first marriage to Arthur and later marriage to Henry.

Caroline of Ansbach exercised real political influence and served as regent several times. Augusta of Saxe Gotha became the mother of George III but never became Queen because her husband died before taking the throne.

Alexandra of Denmark held the title for nearly 38 years, from 1863 until Queen Victoria’s death in 1901. Mary of Teck held it for nine years before becoming Queen in 1910.

Compiled title comparison: Catherine of Aragon held the title for less than five months. Joan of Kent and Diana each held it for about 15 years. Mary of Teck held it for nine years, after an earlier engagement to Prince Albert Victor ended with his death in 1892. Alexandra’s nearly 38 years remain the longest period among these five women.

Diana Changed Public Expectations

Lady Diana Spencer became Princess of Wales when she married Prince Charles on July 29, 1981. She was 20 years old.

Her work with people affected by HIV and AIDS, homelessness, and land mines gave the title a powerful humanitarian identity. Her marriage ended in divorce on August 28, 1996. She lost the style Her Royal Highness but remained known as Diana, Princess of Wales. Her marriage, divorce, charitable work, and continued title are documented in the official Royal Family biography of Diana.

Diana died on August 31, 1997. More than 25 years passed before another woman publicly used the title.

Camilla became legally entitled to Princess of Wales when she married Charles in 2005. She chose Duchess of Cornwall for public use, avoiding confusion and comparisons with Diana. She became Queen when Charles took the throne in 2022.

Catherine therefore became the first woman to publicly use Princess of Wales since Diana. Diana received the title on her wedding day. Catherine entered the role at 40 after more than a decade as a working royal.

What Catherine’s Title Means Today

Catherine’s role carries visibility rather than independent legal power. She supports the King through public engagements, patronages, ceremonial duties, and visits in Britain and overseas.

Early childhood remains a central focus of her public work. Through the Royal Foundation Centre for Early Childhood, she has promoted research and public discussion about pregnancy, infancy, parenting, and child development. Her marriage, current title, charitable priorities, and public duties appear in her official Royal Family biography.

The Welsh connection also requires attention. William and Catherine lived on Anglesey early in their marriage while William worked as a search and rescue pilot. They made their first visit to Wales under their new titles on September 27, 2022.

William did not receive a formal investiture like Charles did at Caernarfon Castle in 1969. That choice reflected a different approach during renewed debate about the title’s history.

Catherine now carries a title shaped by medieval conquest, royal marriage, family succession, and modern public service. Its prestige remains clear. Its history remains contested.

After more than 700 years, the title still asks the same difficult question: how should a modern royal role acknowledge the past while serving people in Wales today?
