Republicanism in the United Kingdom in the context of Middle Ages

Republicanism is a political ideology that encompasses a range of ideas from civic virtue, political participation, harms of corruption, positives of mixed constitution, rule of law, and others. Historically, it emphasizes the idea of self-governance and ranges from the rule of a representative minority or aristocracy to popular sovereignty. It has had different definitions and interpretations which vary significantly based on historical context and methodological approach. In countries ruled by a monarch or similar ruler, or with a monarch whose role is primarily ceremonial such as the United Kingdom, republicanism is simply the wish to replace the hereditary monarchy by some form of elected republic.

Republicanism may also refer to the non-ideological scientific approach to politics and governance. As the republican thinker and second president of the United States John Adams stated in the introduction to his famous A Defense of the Constitutions of Government of the United States of America, the "science of politics is the science of social happiness" and a republic is the form of government arrived at when the science of politics is appropriately applied to the creation of a rationally designed government.

The values and ideals of republicanism are foundational in the constitution and history of the United States. As the United States constitution prohibits granting titles of nobility, republicanism in this context does not refer to a political movement to abolish such a social class, as it does in countries such as the United Kingdom, Australia, and the Netherlands. Instead, it refers to the core values that citizenry in a republic have, or ought to have.

Political scientists and historians have described these central values as liberty and inalienable individual rights; recognizing the sovereignty of the people as the source of all authority in law; rejecting monarchy, aristocracy, and hereditary political power; virtue and faithfulness in the performance of civic duties; and vilification of corruption. These values are based on those of Ancient Greco-Roman, Renaissance, and English models and ideas. Articulated in the writings of the Founding Fathers (particularly Thomas Jefferson, James Madison, and John Adams), they formed the intellectual basis for the American Revolution – the Declaration of Independence (1776), the Constitution (1787), and the Bill of Rights (1791), as well as the Gettysburg Address (1863).

Kenneth Robert Livingstone (born 17 June 1945) is an English politician who served as the Leader of the Greater London Council (GLC) from 1981 until the council was abolished in 1986, and as the first mayor of London from the creation of the office in 2000 until 2008. He also served as the Member of Parliament (MP) for Brent East from 1987 to 2001. He is a former member of the Labour Party, ideologically identifying as a socialist.

Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and several minority groups, despite stiff opposition. The mainstream press gave him the moniker "Red Ken" in reference to his socialist beliefs and criticised him for supporting republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He attempted to stand for the position of Labour Party leader following Neil Kinnock's resignation in 1992, but failed to get enough nominations. Livingstone became a vocal critic of Tony Blair's New Labour project that pushed the party closer to the political centre and won the 1997 general election.

In Welsh and English church history, Independents were a Puritan group who advocated local congregational control of religious and church matters, without any wider geographical hierarchy, either ecclesiastical or political. They were particularly prominent during the Wars of the Three Kingdoms as well under the Commonwealth and Protectorate. The New Model Army became the champion of Independent religious views and its members helped carry out Pride's Purge in December 1648.

Unlike their Presbyterian allies, Independents rejected any state role in religious practice, including the Church of England, and advocated freedom of religion for most non-Catholics. Their religious views led some to back radical political groups such as the Levellers, who supported concepts like Republicanism, universal suffrage and joint ownership of property.
