British Constitution


The British Constitution during the Colonial Era was a collection of laws, customs, and legal precedents that were established over 500 years. The Constitution was significantly affected by the Glorious Revolution, which led to the addition of the English Bill of Rights. Following the French and Indian War, the ideology of the American Revolution developed, based on principles found in the British Constitution.

British Constitution Significance

The British Constitution in the Colonial Era was important to American History because it established a framework of parliamentary sovereignty and the rule of law. These principles were solidified by the Glorious Revolution of 1688 and the passage of the English Bill of Rights. The Constitution ensured the Crown was subject to the will of the people, which was exercised through their elected representatives in Parliament. However, Americans viewed the Constitution in a much different light than most British officials and used it as the basis for the ideology that formed the basis of the American Revolution.

British Constitution History

Magna Carta (1215)

The Magna Carta, also known as the Magna Charta or the “Great Charter,” was a groundbreaking document imposed on King John of England in 1215 by a group of English barons. King John was accused of violating what were considered to be basic rights, including:

  • The right of the church to be free of government interference.
  • The right to own and inherit property.
  • The right to not be subjected to excessive taxes.
  • The right of widows who owned property to not remarry.

It was the first written document aimed at limiting royal authority and outlined specific English liberties the Crown could not infringe upon. These liberties included judicial procedures, limited taxation, and attempts to control Habeas Corpus (the right against unlawful imprisonment). It also marked the establishment of England’s first Parliament, known as the Common Council, consisting of influential men who regulated taxation and were not necessarily loyal to the Crown.

In the early 17th Century, the Magna Carta regained importance as political leaders like Sir Edward Coke referred to it as they opposed the actions of King Charles I. Coke argued the document represented the authority of Common Law and established the Crown could not overstep it. Because of this, the Magna Carta became a symbol of English rights, and its principles of the Rule of Law were often found in colonial charters and, later, state constitutions.

While the Magna Carta guaranteed Habeas Corpus, it did not establish the principle. It is believed to have been established by the 1166 Assize of Clarendon, which also created the principle of trial by jury.

Petition of Right (1627)

In 1627, King Charles I imposed a forced loan on his subjects and imprisoned those who refused to pay. Charles needed the money to pay for an army and to quarter troops in the homes of English subjects.

Parliament responded by adopting the Petition of Right in 1628, which was influenced by Sir Edward Coke. The Petition of Right included four key principles:

  1. Taxes could only be levied on the people with Parliament’s consent.
  2. People could not be arrested without cause (Habeas Corpus), which was guaranteed by the Magna Carta. 
  3. Quartering of troops in people’s homes was illegal.
  4. Martial Law could not be declared during peacetime.

Understanding that Parliament would refuse any future financial grants unless he accepted the petition, Charles I agreed and signed it. While embers of the House of Commons intended for the petition to serve as a Bill of Rights, Charles argued his acceptance of the petition was a favor granted by the Crown instead of a recognition of the rights of the people through their representatives in Parliament.

Habeas Corpus Act (1679)

Following the English Civil Wars, the Stuarts were restored to the throne. In 1679, during the reign of King Carles II, people were often arrested and held for long periods, without charges. Parliament passed the Habeas Corpus Act, which enshrined the right of a person against being unlawfully imprisoned in the Constitution. Although it was largely intended to keep the Crown from imprisoning political opponents, it also stated prisoners could not be transported to various places, including Scotland and New Jersey, before they were convicted.

The Glorious Revolution (1688–1690)

This Glorious Revolution was a sequence of events that culminated in the ascension of two Protestants, King William III and Queen Mary II, to the throne of England, replacing the Catholic monarch, King James II. Although the Revolution contributed to uprisings in Massachusetts (Boston Revolt), New York (Leisler’s Rebellion), and Maryland (Coode’s Rebellion), it led to the Revolution Settlement of 1689, which was a significant step forward for the Constitution.

The primary cause of the Glorious Revolution was the actions of King James II, who was Catholic. After succeeding his brother, Charles II, in 1685, James was popular. However, he started to abuse his authority, bypassing Parliament to ease restrictions on Catholics and Nonconformists (Separatists and Puritans).

In April 1688, James issued the Declaration of Indulgence, which many members of the clergy refused to read from their pulpits. The Archbishop of Canterbury and six bishops petitioned the crown, arguing the declaration was illegal. James responded by prosecuting them for seditious libel, but a jury acquitted them in June, undermining his authority.

On June 10, 1688, a son,  James Francis Edward, was born to King James II and his wife. The baby was baptized Catholic, and his birth meant that his Protestant daughters from a previous marriage would no longer be first in line for the throne, raising fears of a Catholic dynasty. 

In response, a group of influential politicians, concerned about the prospect of a Catholic heir and James’s pro-Catholic rule, invited William of Orange, James’s nephew and the husband of his daughter Mary, to England to defend the Protestant Cause and the English Constitution.

William landed in England on November 5, 1688, with over 14,000 Dutch troops under his command. In the wake of the invasion, some of James’s key political and military supporters abandoned him, including his daughter Anne.

Despite having a larger army, James chose not to engage William in combat. James fled England in December 1688, leaving the throne vacant and allowing William to take control of London.

In January 1689, Parliament convened to address the crisis and determined that James had abdicated his throne by violating the Constitution and fleeing the country. Consequently, this Parliament, known as the Convention Parliament, declared Mary and William, who were first and third in the Protestant line of succession, as joint sovereigns in February 1689.

On April 11, 1689, Mary and William were crowned as monarchs. During their coronation, they read aloud the Declaration of Rights, which outlined the constitutional principles and protections they had agreed to. The declaration was passed into law as the Bill of Rights, the first step in the Revolution Settlement, solidifying the principles of parliamentary sovereignty and individual liberties within the English Constitution.

Repercussions in Scotland and Ireland

In Scotland, Presbyterians responded by removing bishops from their leadership positions in the church, whom James had supported. Supporters of James and the Stuart Line, who were also Catholic, became known as Jacobites. Many of these supporters were located in the Scottish Highlands, and they remained loyal to the Stuarts and eventually supported two Jacobite Rebellions:

  1. In 1715, James Edward Stuart, the son of King James II, led a failed rebellion. James Edward was known as the “Old Pretender.”
  2. In 1745, Charles Edward Stuart, the son of James Edward and grandson of King James, led another failed rebellion. Charles Edward was known as the “Young Pretender” and “Bonnie Prince Charlie.”

Many of the Scots Highlanders who were defeated at the Battle of Culloden (April 16, 1746) eventually emigrated to America.

In Ireland, the Catholic majority welcomed James II and his army to Dublin in March 1689. A Catholic parliament, later called the “Patriot Parliament,” reinstated political and economic rights for Catholics and acknowledged James as King of Ireland. However, William III’s forces defeated James at the Battle of the Boyne (July 1, 1690). Afterward, James fled to France and Protestants took control of Ireland.

The Revolution Settlement (1688–1689)

After King James II abdicated the throne, Parliament enacted a series of laws that established parliamentary sovereignty, meaning that Parliament had the ultimate authority over the Crown. Known as the Revolution Settlement, it included important governmental reforms carried over from Oliver Cromwell’s Protectorate, such as a mixed government with a single executive and advisory council, both dependent on a two-house (bicameral) legislature. The reforms also mandated regular elections, parliamentary oversight of taxation, and limited religious toleration. 

The key pieces of of the Revolution Settlement, which expanded the Constitution were:

  1. Bill of Rights (1689) — This document reasserted traditional English liberties, banning standing armies without Parliament’s consent, prohibiting the monarch from suspending or dispensing laws, ending taxation without Parliament’s consent, and guaranteeing the freedom to petition the crown, hold free elections, and have frequent Parliaments.
  2. Toleration Act (1689) — This act gave dissenters from the Church of England limited rights to worship freely and publicly.
  3. Triennial Act (1694) — This law ensured that the monarch could not rule without Parliament, requiring that Parliament meet at least once every three years and mandating new elections at least every three years.

Act of Settlement (1701)

Act of Settlement secured the Protestant succession to the throne and ensured an independent judiciary. Following the unexpected death of Prince William, the Duke of Gloucester, in 1700, there was a succession crisis, because the next heirs in line were Catholic, not Protestant.

To address this issue, the Act of Settlement was passed in 1701. It bypassed over 50 Catholic heirs, designating Sophia, Electress of Hanover, and her heirs as successors to the throne. Sophia was the granddaughter of James I and the nearest Protestant in the direct line of descent from the Stuarts. The Act of Settlement excluded Catholics and those married to Catholics from the throne and required the monarch to swear to maintain the Church of England.

The Act of Settlement further strengthened Parliament’s constitutional authority by introducing several key provisions:

  • The monarch could not engage in war or leave the country without Parliament’s consent.
  • Foreigners were banned from holding English offices or being awarded English land.
  • Judicial independence was secured by ensuring judges could only be removed by a vote of Parliament, not at the will of the Crown.

Scotland did not follow along with England in this measure. Instead, it passed the Act of Security (1704) that gave it the power to reject the English monarch. This escalated tensions between Scotland and England. 

Scotland prepared its militia and England ordered its warships to return home. In response, England passed the Alien Act of 1705, treating Scotland as a foreign nation and banning trade with it unless the Scottish Parliament accepted the Hanoverian Succession. This ultimatum led to negotiations for a union, resulting in the creation of Great Britain in 1707. 

The Acts of Union Creates the Kingdom of Great Britain

From 1603, England and Scotland were only united through a shared monarch and maintained separate Parliaments. The union was tested by the dispute over the Act of Settlement, the Act of Security, and the Alien Act.

At the time, the economy of Scotland was struggling due to poor harvests and a failed attempt to establish a colony in Panama, known as the Darien Scheme. Meanwhile, England was involved in the War of Spanish Succession with France. Despite the disagreement of the line of succession, both nations wanted to avoid a costly conflict. Commissioners were appointed and they negotiated a which was ratified by the Scottish Parliament in January 1707 and by the English Parliament in March 1707.

The Acts of Union abolished the separate states and parliaments of England and Scotland, creating the Kingdom of Great Britain, with the following provisions:

  • Great Britain had one monarch, one parliament, and equal rights in trade. 
  • The Church of Scotland was given an equal position with the Church of England.
  • Scotland’s legal and local political systems were guaranteed
  • Representation in the British Parliament consisted of 45 Members of Parliament from Scotland and 16 Scottish peers elected to the House of Lords. 
  • It also included financial compensation for Scottish investors to cover their losses from the Darien Project.

Stabilizing the Constitution

The Constitution was further stabilized by the 1714 Hanoverian Succession, which saw King George I ascend the throne of England and Ireland, and the defeat of the Jacobite rebellions in 1715 and 1745. These events helped solidify the political system, allowing debate without the threat of civil war.

British Constitution and the American Revolution

By the end of the 1745 Jacobite Rebellion, the 13 Original Colonies were fully established. Within the next decade, France and England were engaged in the French and Indian War, the final war for control of North America.

Following the death of King George II on October 25, 1760, his son ascended the throne and became King George III. In Massachusetts, Charles Paxton, a customs official, asked Lieutenant Governor Thomas Hutchinson — who was also head of the Massachusetts Superior Court — to issue new Writs of Assistance, which a group of Boston merchants opposed.

James Otis, a prominent lawyer, agreed to represent the merchants, who filed a lawsuit, arguing the renewal of the was illegal, based on the British Constitution. During the proceedings, Otis is believed to have given a fiery speech that lasted for at least five hours.

Otis based his arguments on Natural Law and the British Constitution. Although the law and precedent favored the legality of the Writs, Otis argued the Writs allowed unlawful search and seizure of property and violated the inherent natural rights of people to feel safe in their homes. Otis famously said, “…one of the most essential branches of English liberty is the freedom of one’s house. A man’s house is his castle…”

Years later, John Adams, a Founding Father and Second President of the United States recalled, “Otis was a flame of fire…American Independence was then and there born.”
