The Full Story
Before 1829, there was no police force in Britain. There were watchmen, parish constables, and the army. If disorder broke out, the government sent soldiers. And soldiers, as Peterloo proved in 1819, tended to kill people.
Robert Peel saw a different way. As Home Secretary, he pushed the Metropolitan Police Act through Parliament in 1829, creating the world's first professional civilian police force. But what made it revolutionary was not that it existed. It was how it worked.
Peel's nine principles of policing established something that had never existed anywhere in the world: policing by consent. The police were not an army. They were citizens in uniform. Their power came not from the government but from the public's willingness to cooperate. They carried no firearms. They wore blue, not military red, deliberately distinguishing themselves from soldiers. Their job was to prevent crime, not to punish it.
The most radical principle was this: the police are the public and the public are the police. Officers were simply members of the community paid to give full-time attention to duties that every citizen shared. They held no special powers beyond those of any ordinary person. They could not compel obedience through fear. They had to earn trust.
This was an extraordinary idea. In most of the world, police forces existed to enforce the will of the ruler. In Britain, the police existed to serve the people. The Peelian principles became a model exported across the common-law world, from Canada to Australia to New Zealand. The idea that a police officer answers to the community, not the state, began in London in 1829.
Why This Matters
The Peelian principles are not just historical curiosities. They are the foundation of a fundamentally different relationship between state power and the individual. In countries where police serve the government, citizens fear the knock on the door. In countries built on policing by consent, the officer is a neighbour, accountable to the community. Every time that principle is upheld, it traces back to a decision made in 1829 that the people of Britain would never be policed by an army. Every time it is eroded, we lose something that took centuries to build.
Key Facts
- ⚠In most countries, police work for the government / serve the state, Defensible generalisation. The majority of the world's police forces historically developed from military or paramilitary models (French Gendarmerie model, colonial police forces, authoritarian state police). The concept of police accountability to the public rather than the state is not universal. Many democracies have since adopted elements of consent-based policing, but the origin and default model worldwide was state-serving.
- ✓Metropolitan Police Act 1829, The Metropolitan Police Act 1829 (10 Geo. 4, c. 44) was passed by Parliament on 19 June 1829. It established the Metropolitan Police of London. Sir Robert Peel, Home Secretary, introduced the bill. (Parliamentary archives; National Archives)
- ✓Sir Robert Peel was Home Secretary, Robert Peel served as Home Secretary 1822-1827 (under Lord Liverpool) and 1828-1830 (under the Duke of Wellington). He introduced the Metropolitan Police Act during his second term. (Standard biographical record)
- ✓Before 1829, London had no professional police force, London's law enforcement before 1829 consisted of parish constables, night watchmen, the Bow Street Runners (est. 1749), and various private arrangements. There was no unified professional police force. (Multiple academic sources; Clive Emsley, "The English Police: A Political and Social History")
- ✓London was the largest city in the world, By the 1820s, London's population exceeded 1.5 million, making it the largest city in the world. It surpassed Beijing around 1825. (Census records; historical demography)
- ⚠Night watchmen, old men with lanterns, often ineffective, Night watchmen (the "Watch") were a longstanding feature of London's parish-based policing. They were frequently criticised as elderly, poorly paid, and ineffective. "Mostly useless" is a narrative compression but reflects contemporary criticism. The satirist and magistrate Patrick Colquhoun described the Watch as inadequate in his 1795 treatise.
- ✓Thief-takers, bounty hunters, many corrupt, Thief-takers operated on a reward system, paid per conviction. The most notorious, Jonathan Wild (1682-1725), was himself a criminal mastermind who controlled a network of thieves and fenced stolen goods while claiming rewards. The system was widely recognised as corrupt. (Old Bailey records; historical accounts)
- ✓Bow Street Runners established 1749 by Henry Fielding, The Bow Street Runners were established c.1749 by the magistrate and novelist Henry Fielding at the Bow Street Magistrates' Court. They were the first professional police force in London but never numbered more than a few dozen. (J.M. Beattie, "The First English Detectives")
- ✓1,000 officers on the first day,29 September 1829, The Metropolitan Police began operations on 29 September 1829 with approximately 1,000 officers (the target was 3,000 but initial recruitment was slower). The first patrols went out that evening. (Metropolitan Police historical records)
- ✓Officers called "Peelers" or "Bobbies" after Peel, Both nicknames derive from Sir Robert Peel's name. "Bobby" (from Robert) became the enduring popular term. "Peeler" was also used, especially in Ireland where Peel had earlier established the Royal Irish Constabulary. (Standard historical record; OED)
- ✓Officers were deliberately unarmed, carried only a truncheon, Metropolitan Police officers carried a wooden truncheon and a rattle (later replaced by a whistle). They were deliberately not armed with firearms. This was a conscious decision to distinguish them from the military. (Metropolitan Police historical records; Clive Emsley)
- ✓Blue civilian-style tailcoats, NOT military red, Officers wore dark blue swallow-tail coats with brass buttons and a reinforced top hat (later the custodian helmet). The dark blue colour was deliberately chosen to distinguish them from the red-coated military. The design was civilian, not military. (Metropolitan Police historical records; Museum of London)
- ✓Charles Rowan and Richard Mayne were the first two Commissioners, Colonel Charles Rowan (a military officer, Waterloo veteran) and Richard Mayne (a barrister) were jointly appointed as the first two Commissioners of the Metropolitan Police in 1829. They served together for many years, Rowan until 1850, Mayne until 1868. (Metropolitan Police records)
- ⚠The 9 Peelian Principles, The "Peelian Principles" are widely attributed to Peel, Rowan, and Mayne. However, their exact origin is debated. They do not appear in the Metropolitan Police Act itself. The earliest known codification in nine-principle form appears in a 1829 instruction book to Metropolitan Police officers ("General Instructions"), but some historians argue the specific nine-point formulation was articulated later. The principles accurately reflect the documented philosophy of the early Metropolitan Police. Their content is not disputed, only the precise moment of codification.
- ✓Principle 7: "The police are the public and the public are the police", This is the most frequently quoted of the Peelian Principles. It appears in the "General Instructions" issued to officers. The exact wording: "the police are the public and the public are the police; the police being only members of the public who are paid to give full-time attention to duties which are incumbent on every citizen."
- ✓French Gendarmerie, military police serving the state since 1791, The Gendarmerie nationale was formally established in 1791 (reorganising the earlier Marechaussee, which dates to the Middle Ages). It is a military force under the authority of the Ministry of the Interior (and partially the Ministry of Defence). Gendarmes are soldiers with police duties. (French government records; standard military history)
- ⚠Most of the world copied the French/military model, Defensible generalisation. Colonial police forces (British, French, Spanish, Portuguese, Dutch) were typically paramilitary in structure. Many post-colonial police forces inherited this model. The French Gendarmerie model was explicitly exported to many European and colonial nations. However, many nations have since adopted elements of community or consent-based policing. The claim is about historical origin and default, not current universal practice.
- ✓British police remained largely unarmed for nearly 200 years, Routine arming of British police officers has never been standard practice. From 1829 to the present day, the vast majority of British police officers are unarmed (carrying only a baton, CS spray, and in recent years a Taser). Armed response units (Authorised Firearms Officers) are specialist exceptions. England, Wales, Scotland, and Northern Ireland (PSNI carries firearms) differ in practice. The 200-year claim is accurate for the general principle.
- ✓The consent-based policing model was exported globally, The Peelian model influenced policing in many Commonwealth nations (Australia, New Zealand, Canada) and beyond. The concept of policing by consent became a foundational principle in democratic policing worldwide. (Academic policing literature; Commonwealth policing histories)
