In 1829, British statesman Sir Robert Peel established some organization in London, and ever since, its members have been identified by his nickname. What is it?

In 1829, then-Home Secretary Sir Robert Peel pushed the Metropolitan Police Act through the British Parliament, establishing the first professional, centrally-organized police force in London. This new force of 1,000 constables replaced an inadequate and disjointed system of parish watchmen and local constables who were struggling to cope with rising crime in the rapidly growing city. The public quickly coined nicknames for the new officers, deriving them from the founder's name. They were often called "Peelers" after his surname, but the more affectionate diminutive of his first name, "Bobbies," is the term that has endured for nearly two centuries.

Peel's vision was to create a disciplined force focused on preventing crime rather than just reacting to it. Initially, the "Bobbies" were not universally welcomed; some citizens viewed them with suspicion, fearing they could become an instrument of government oppression. The officers were issued a uniform that included a distinctive top hat, a truncheon, and a rattle to call for assistance, which was later replaced by a whistle (Review). Despite the initial skepticism, the new police force proved highly effective at cutting crime, and the "Bobbies" eventually became a respected symbol of London. Peel's model was so successful that it became the blueprint for modern policing, and by 1857, all cities in Britain were required to have their own police forces.
