Robert Peel and the birth of the Metropolitan Police
A Police Crisis
By 1820 London was the largest city in the world. Its population had passed one million; its docks handled more cargo than any other port; its streets were crowded with horses, traders and migrants. But the system of policing was almost unchanged from Tudor times. Each parish appointed unpaid parish constables and night watchmen — sometimes called ‘Charlies’. They were unpaid or paid very little, served part-time, and were widely mocked as old, drunk or asleep on duty.
The army filled the gap when riots broke out, but soldiers were poorly suited to civilian crowd control. The Peterloo Massacre of 1819 — in which yeomanry cavalry killed eighteen protestors at a peaceful Manchester rally — showed the political cost of using the army for policing. Yet calls for a new police force met long-standing public suspicion. Britons feared a uniformed force would resemble the secret police of revolutionary France: a tool of state spying, not local justice. Reform therefore had to be designed to reassure the public, not just to catch criminals.
The Bow Street Runners: A First Attempt
The first organised paid policing in London predated 1829 by eighty years. Henry Fielding, the novelist and London magistrate, recruited a small group of men in 1749 to investigate crime from his Bow Street courtroom. They became known as the Bow Street Runners. Fielding’s blind half-brother John Fielding — said to be able to recognise 3,000 criminals by their voices — took over the Bow Street court after Henry’s death and expanded the operation. From 1763 a mounted Horse Patrol swept the main roads out of London.
The Runners were a success on their own terms but a small one: never more than a few dozen men, paid partly by reward, working only out of central London. They had no national reach and no presence in the rapidly growing industrial cities. They were absorbed into the Metropolitan Police in 1839. Their importance is that they proved a paid, organised force could work and be politically tolerable — an example for the much larger reform that followed.
Students often claim that Robert Peel invented organised policing in 1829. He did not. Tithings, parish constables and night watchmen had policed England for nearly a thousand years. The Bow Street Runners had been an organised, paid force in London since 1749. What Peel did was professionalise existing efforts and unify them under a single command, with full-time pay, uniform and beats. Calling 1829 the start of policing misses the eighty years of Bow Street experience that made it possible. Place Peel as a figure of continuity as well as change, not as the sole inventor of policing.
Robert Peel as Home Secretary
Robert Peel became Home Secretary in 1822. He inherited the Bloody Code in its full form — over 200 capital offences. Between 1823 and 1827 he led a major penal reform, repealing several hundred capital statutes and reducing the offences for which one could be hanged. Death remained on the books for murder and treason, but ordinary property crime was now mostly punishable by transportation or prison. This reform mattered because Peel was preparing the ground for a police force: harsh laws were more enforceable when paired with proportionate punishment.
In 1829 Peel introduced the Metropolitan Police Act. The Act created a single force for the London area (excluding the City of London, which kept its own force). Headquarters were at Scotland Yard, on Whitehall Place; the back entrance, which became the public face of the force, gave it its informal name. The first commissioners were Sir Charles Rowan and Sir Richard Mayne, who together drafted the rules of conduct emphasising prevention, civility and the consent of the governed.
Peelers, Bobbies and Beat Patrols
The new police were nicknamed ‘Peelers’ or ‘bobbies’, both after their founder. Their design was deliberately reassuring. Officers wore a blue coat and top hat — not military red. They carried only a wooden truncheon and a rattle, not a firearm. They worked fixed beats: each constable patrolled a defined route on foot, day or night, so the public knew which officer to expect and the officer learned the people. The aim was prevention through visible, regular presence, not investigation after the fact.
Recruitment standards were strict by the standards of the day. Recruits had to be under 35, at least 5 feet 7 inches tall, literate and of good character. They were full-time and salaried — not paid by reward. The first three years saw heavy turnover — many recruits were dismissed for drunkenness — but by the mid-1830s a stable corps of around 3,000 officers was in place.
Peel’s force was deliberately civilian: blue coat (not red), wooden truncheon (not firearm), fixed foot beats and a focus on prevention. The 1829 Metropolitan Police Act created the force; Sir Robert Peel was Home Secretary and Sir Richard Mayne and Sir Charles Rowan were the first commissioners.
It is tempting to imagine the new police were welcomed at once. They were not. Many Londoners ridiculed them as ‘raw lobsters’ and ‘blue plagues’. There were violent attacks: PC Robert Culley was killed at a riot in Coldbath Fields, Clerkenwell in 1833 and a coroner’s jury initially returned a verdict of ‘justifiable homicide’. Public acceptance came only over the 1830s and 1840s, helped by visible reductions in crime, by the bobby’s unarmed civility and by the sheer fact of seeing the same officer on the same beat every day. The point to make is that public consent was earned, not given.
Spreading the Model: County Forces and CID
The Met covered only the London area. Outside London, parishes still relied on their old constables. Two Acts changed that. The 1839 County Police Act gave magistrates the option of setting up a paid county force, modelled on the Met. Many counties did so; many did not, on grounds of cost. The 1856 County and Borough Police Act made paid forces compulsory in every county and borough. By the late 1850s, every part of England and Wales had a Peel-style police force.
Detective work followed. The 1842 Detective Branch was a small unit of plain-clothes officers based at Scotland Yard. They handled serious crime that the uniformed beats could not pursue. In 1878, after a corruption scandal, the Branch was reorganised and renamed the Criminal Investigation Department (CID), with stricter recruitment and supervision. By the 1880s CID had several hundred officers and was the model copied by other forces. It would soon be tested by the Whitechapel murders of 1888 — the subject of this unit’s historic environment study.
Key dates: 1749 Bow Street Runners; 1829 Metropolitan Police Act; 1839 County Police Act (optional county forces); 1842 Detective Branch; 1856 County and Borough Police Act (compulsory forces nationwide); 1878 CID created.
