Dissatisfaction with British rule led to a longer period of agitation in the early 19th century, with failed republican revolutions in Canada in the late 1830s and Ireland in 1848.
Another "significant incarnation" of republicanism broke out in the late 19th century, when Queen Victoria went into mourning and largely disappeared from public view after the death of her husband, Prince Albert.
More recently, in the early 21st century, increasing dissatisfaction with the House of Windsor, especially after the death of Elizabeth II in 2022, has led to public support for the monarchy reaching historical lows.
The Commonwealth Parliament represented itself as a republic in the classical model, with John Milton writing an early defence of republicanism in the idiom of constitutional limits on a monarch's power.
Cromwell and Thomas Fairfax were often ruthless in putting down the mutinies which occurred within their own army towards the end of the civil wars (prompted by Parliament's failure to pay the troops).
Whereas Charles I had been in part restrained by a Parliament that would not always do as he wished (the cause of the civil war), Cromwell was able to wield much more power as only loyalists were allowed to become MPs, turning the chamber into a rubber-stamping organisation.
It is often suggested that offering Cromwell the crown was an effort to curb his power: as a king, he would be obliged to honour agreements such as Magna Carta, but under the arrangement he had designed he had no such restraints.
[15] He and other British republican writers saw in the Declaration of Independence (4 July 1776) a legitimate struggle against the Crown, that violated people's freedom and rights, and denied them representation in politics.
[citation needed] From the start of the French Revolution into the early 19th century, the revolutionary blue-white-red tricolour was used throughout England, Wales and Ireland in defiance of the royal establishment.
It was however often accompanied by slogans consisting of three words such as "Fraternity – Liberty – Humanity" (a clear reference to Liberté, égalité, fraternité), and adopted by the Chartist movement in the 1830s.
[20] During the later years of Queen Victoria's reign, there was considerable criticism of her decision to withdraw from public life following the death of her husband, Prince Albert.
According to Mortimore, this "was commissioned for a Panorama programme to mark Prince Charles's eighteenth birthday, and the poll found that 'about a sixth of the British people think they would like to see the monarchy abolished'.
In Crown and People (1978), royal historian Philip Ziegler summarised public opinion on the monarchy in the quarter-century between Elizabeth II's accession to the throne and her Silver Jubilee in 1977: "In the years after 1953 Britain entered the age of the psephologist.
More and more often allegedly representative cross-sections of the British people found themselves interrogated about their views on abortion, religion, washing-machines, national politics or pornographic films."
He notes that on thirteen occasions between 1953 and 1976, via varying questions, the public were asked whether they would prefer Britain to continue with a monarchical form of government or for the country to become a republic.
[39] In January 1997, ITV broadcast a live television debate Monarchy: The Nation Decides, in which 2.5 million viewers voted on the question "Do you want a monarch?"
Speaking for the republican view were Professor Stephen Haseler, (chairman of Republic), agony aunt Claire Rayner, Paul Flynn, Labour MP for Newport West and Andrew Neil, then the former editor of The Sunday Times.
Those in favour of the monarchy included author Frederick Forsyth, Bernie Grant, Labour MP for Tottenham, and Jeffrey Archer, former deputy chairman of the Conservative Party.
The debate was conducted in front of an audience of 3,000 at the National Exhibition Centre in Birmingham, with the telephone poll result being that 66% of voters wanted a monarch, and 34% did not.
From the 1990s until the 2010s, republican MP Dennis Skinner regularly made a retort to Black Rod, the official who commands the House of Commons to attend the speech.
[43] In a 2006 feature marking the Queen's 80th birthday, Time magazine quoted MORI founder Robert Worcester on this issue, who called it "the most stable measure in British polling".
[45] Support for the monarchy appeared to strengthen in the early to mid-2010s, when the Queen celebrated her Diamond Jubilee, and her grandson, who was second in line to the throne, got married in a ceremony broadcast on live television; both events were marked by public bank holidays.
Such MPs included Richard Burgon, Laura Pidcock, Dennis Skinner, Chris Williamson, Paul Flynn, Jeff Smith, and Emma Dent Coad.
In May 2021, a YouGov poll showed reduced support for the monarchy, with 61% in favour and 24% against among all over-18s; there was a particularly high rise in republican views and an overall plurality for its replacement with an elected head of state in the 18–24 age group (41%–31%).
[59] Protests against King Charles III have included blank pieces of paper, heckling during royal processions involving Prince Andrew, and egging attempts.
[80] The organisation held an event at the Labour Party's annual conference on 25 September 2022, which attracted large crowds, and included The Guardian's columnist Polly Toynbee, author Paul Richards, and expert in constitutional law Dr Adam Tucker as panellists.
[80] In response to the Labour Party's decision to sing "God Save the King" at the conference, panellists and those who attended the event said they did not want to see it booed or heckled.
The group has benefited from occasional negative publicity about the Royal Family, and Republic reported a large rise in membership following the wedding of then-Prince Charles and Camilla Parker-Bowles.
[29] Since then, the results suggest a long-term decline in support for the institution, with 2023 survey data showing the number of people who said the monarchy was "very important" falling to 29%, an all-time low.
The advocacy group Republic argues that: The monarchy is an unaccountable, expensive and outdated institution, it is unrepresentative of modern Britain, and it also gives politicians significant unchecked powers.
