Early history
Alfred the Great was the king of England for some time in the 9th century. (QR: Revenge of the Judoon, IDW: They Think It's All Over)

Athelstan of England was the king of England for some time in the 10th century. He received the Cup of Athelstan in 924 as a coronation gift from Hywel, King of the Welsh. (DW: Planet of the Dead)

Harold Godwinson was king of England for most of 1066. After he defeated a Viking invasion, the Normans invaded England from the south. The Monk planned to change history by using advanced technology to aid King Harold, ensuring that his army would be better able to face the Normans. This plan was defeated by the First Doctor and Harold was later defeated in the Battle of Hastings by William the Conqueror, who became the new king of England. (DW: The Time Meddler)

Richard I of England (8 September 1157 – 6 April 1199), nicknamed Richard the Lionheart, was King of England from 6th July 1189 until his death. While he led his troops in the crusades, he worried that his younger brother John of England would usurp his throne back in England. Richard assisted the First Doctor and Ian Chesterton in reclaiming Barbara Wright after her capture by Arabs. (DW: The Crusade)

King John of England ruled England in the early 13th century. While the real King John was in London taking the Crusader's Oath, the android Kamelion was being used in a plot by the Master to sabotage Earth history by preventing King John's signing of the Magna Carta, an event pivotal to the development of parliamentary democracy on that planet. This plot was foiled by the intervention of the Doctor. (DW: The King's Demons)

16th century
Henry VIII was the King of England from 1509 to 1547. The First Doctor once argued with Henry VIII so that he would be sentenced to the Tower of London where the TARDIS was located. (DW: The Sensorites) However, on a later occasion the Doctor claimed that he had never met him. (NA: Tragedy Day) The Tenth Doctor later mentioned having dinner with him. (QR: Revenge of the Judoon) Elizabeth X stated that Doctor was an old drinking buddy of his. (DW: The Beast Below)

After the death of Henry's successor, Edward VI, Jane Grey became queen at 16 years old as her father wished, although she never wanted to rule. She met Rani Chandra on 19 July 1553, the ninth and final day of her reign. Rani was found by Mistress Ellen, who believed her to be the queen's new lady in waiting. Rani played along to further her plot: Ellen presented Rani to Jane, who gave her a music box. Jane liked Rani because she spoke to her as a girl and not a queen and became friends with her. Jane learned that Mary I of England had claimed the throne and proclaimed her a traitor, intending to sentence her to death. Lady Matilda tried to kill Jane that night so she would be a martyr, but Rani stopped her. Rani worked out that the dagger Matilda tried to kill Jane with was the object the Shopkeeper was after. She retrieved it and stayed to comfort Jane before using it to teleport back to 2010. Jane suspected Rani was an angel and this strengthened her. Before her death she wrote to her sister knowing that she had achieved immortality as Rani had told her earlier that she would be remembered for centuries to come. (SJA: Lost in Time)

The Sixth Doctor and Evelyn Smythe met Mary when they travelled back to 1554 to fix a time anomaly. (BFA: The Marian Conspiracy)

Elizabeth I was the Queen of England from 1558 to 1603, and an apparent spouse of the Tenth Doctor. He met her after she had met him; this meant there was a back story of which he was unaware.

Some time after his adventure on Bowie Base One, the Doctor returned to 16th century England, where he met Elizabeth for the first time — from her perspective. He told Ood Sigma that he married "Queen Bess", and implied that "her nickname" no longer applied. Elizabeth had multiple epiphets including "the Virgin Queen" and "Good Queen Bess" (BFA: The Marian Conspiracy), but as the Doctor stopped mid-sentence, what precisely he was referring to remained unclear. Later, when the Doctor met Elizabeth X, she made a passing remark that "the Virgin Queen" was indeed the nickname the Doctor had been referring to. (DW: The Beast Below)

17th century
After the death of Elizabeth I, James I of Scotland inherited the English throne. From then onwards, both kingdoms were ruled by a single monarch.

Charles I reigned during the English Civil War. The Second Doctor played a role in the civil war which brought down Charles I and led to his execution and the rise of Oliver Cromwell in 1649. (PDA: The Roundheads) Parliament ruled until 1660, then Charles II ruled until 1685.

18th century

Victoria, Queen of Great Britain and Ireland, Empress of India, usually known as Queen Victoria, was a powerful and influential monarch on Earth in the 19th century, ruling from 1837 to 1901. Her reign, known as the Victorian era, was marked by tremendous strides in technology and the arts in Britain and elsewhere. Victoria met the Doctor at least twice: once during her coronation in 1838, and in 1879 she shared an adventure with the the Tenth Doctor. The latter encounter led her to banish the Doctor from her country and form the Torchwood Institute, as the British Empire's defense against the dark forces with which the Doctor seemed to consort.

20th century
Edward VII was King of Great Britain from 1901 to 1910.

Edward VIII was King of Great Britain for most of 1936.

When Edward announced his plans to marry his mistress, the twice-divorced American Wallis Simpson, British Prime Minister Stanley Baldwin informed him that neither his subjects nor the British government would accept the marriage. After weeks of deliberation, the King claimed to have chosen to abdicate. Manipulated by the Players, he was planning to dissolve Parliament and replace it with one more loyal to him. He was thwarted by the Sixth Doctor, Peri Brown and Winston Churchill. They used a recording of the speech Edward would have given to coerce him into abdicating the throne, threatening to have him charged with treason. (PDA: Players)

Elizabeth II was also apparently no longer on the throne at the time the Doctor reunited with the Brigadier for an adventure "several years" into Ace's future, probably some time in the 1990s. (DW: Battlefield) However, she was later restored to the throne.

Queen Elizabeth was briefly deposed by the Ice Lord Xznaal in May 1997, but was later restored to the throne and her recoronation was held on 23 November. (NA: The Dying Days)

21st century
In 2001, Dr. Who, a fictional duplicate of the Doctor, tried several times to assassinate Elizabeth, convinced she was the leader of an oppressive regime. During an appearance in Sheffield he succeeded, but the self-doubts of his accomplice Jason, coupled with his own fictional nature, meant that the Queen survived after all. (NA: Head Games)

In 2006, Harriet Jones was invited to form a government by the Queen. (WEB: UNIT website (Secure section)) On Christmas Day of that year, the blood control powers of the Sycorax (operating out of a ship hovering over London) threatened to make Elizabeth II, as well as the rest of the British royal family jump off a roof and kill herself. (DW: The Christmas Invasion)

After the Battle of Canary Wharf (DW: Doomsday) in 2007, the Queen ordered the immediate closure of Torchwood One. (WEB: torchwood.org.uk) The level of her involvement with and support of the Torchwood Institute, established by Victoria, both before and after the Battle of Canary Wharf, is unclear.

Due to the Sycorax and "Christmas Star" incident (DW: The Runaway Bride) occuring on consecutive Christmases in London, most of the city's residents fled during Christmas 2008. The Queen staunchly decided to remain in Buckingham Palace.(DW: Voyage of the Damned) On Christmas Day, the alien Titanic almost crashed into Buckingham Palace; the Doctor telephoned the Palace and spoke a pre-arranged code number that resulted in the immediate evacuation of the Queen and her staff, but at the last moment he was able to pull the ship up above the palace.

In 2050 when the British government was controlled by Lomax, a Korven from the Far future, Britain was ruled by an unnamed King. An Oroborus arrived on Earth around his birthday, causing time distortions which meant that some people complained about missing the King's birthday message, and others saw it twice. (K9TV: Oroborus)

Far future
Elizabeth X of the United Kingdom, (also known as Liz Ten) was the Queen Regnant of the United Kingdom of Great Britain and Northern Ireland when Earth was devastated by solar flares in the late 30th century. She had grown up on stories of the Doctor, as had her whole family.

Liz Ten found a star whale and enslaved it (or so she thought she had; in actuality it volunteered) to form the base of Starship UK. She then wiped her mind so that she would not have to deal with the consequences. Her government slowed down her body clock, keeping her effectively immortal. She thought she was fifty and had been on the throne for ten years, not knowing she always lived the same ten years, always found out the truth about Starship UK at the end of it, and always wiped her mind once more. She placed this system throughout the ship and everyone would always choose to forget. Those who didn't were sent below, to fuel the star whale. She feared that if the star whale was freed, it would fly off, killing all who lived on the ship. She wore a mask to disguise herself from the public whilst investigating.

Three hundred years later, when the Doctor and Amy Pond came to Starship UK, they found out the truth and told Elizabeth. Amy freed the star whale whichcontinued to carry Starship UK as it was old, kind and the last of its species, just like the Doctor. Liz was able to live a happy life along with her kingdom. (DW: The Beast Below)

In Arthur's World, a parallel universe, Arthur was King of England in the 8th century.

Together with his knights and Merlin, Arthur battled the forces of Mordred and Morgaine, but was killed at the Battle of Camlann. Merlin, a future incarnation of the Doctor, placed Arthur's body and Excalibur in a dimension-crossing spaceship and hid it at the bottom of Lake Vortigern, near Carbury, in rural England. Legends sprang up that Arthur had survived the battle, albeit badly wounded, and would reawaken at the time of England's greatest need.

In the late 20th century, the Doctor and Ace discovered Arthur's spaceship and retrieved Excalibur. They found that stories of Arthur's survival were just propaganda and the King was really dead after all. (DW: Battlefield)

Edward IX was King of England in a more technologically advanced parallel universe. (TVA: Who's Who?)
