A regiment is a military unit. Its role and size varies markedly, depending on the country, military service, service, or administrative corps, specialisation.

. Police typically wear distinctive hats such as
peaked caps or
brimmed hats, such as those worn by the
Royal Canadian Mounted Police. Some hats have a protective function. As examples, the
hard hat protects construction workers' heads from injury by falling objects, a British police
Custodian helmet protects the officer's head, a
sun hat shades the face and shoulders from the sun, a
cowboy hat protects against sun and rain and an
ushanka fur hat with fold-down earflaps keeps the head and ears warm. Some hats are worn for ceremonial purposes, such as the
mortarboard, which is worn (or carried) during university graduation ceremonies. Some hats are worn by members of a certain profession, such as the
Toque worn by chefs, or the
mitre worn by Christian
bishops. Adherents of certain religions regularly wear hats, such as the
turban worn by
Sikhs, or the
church hat that is worn as a
headcovering by Christian women during prayer and worship.
History

While there are not many official records of hats before 3,000 BC, they probably were commonplace before that. The 27,000-to-30,000-year-old
Venus of Willendorf figurine may depict a woman wearing a woven hat. One of the earliest known confirmed hats was worn by a
Bronze Age
The Bronze Age () was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age is the middle principal period of ...
man (nicknamed
Ötzi) whose body (including his hat) was found frozen in a mountain between Austria and Italy, where he had been since around 3250 BC. He was found wearing a bearskin cap with a chin strap, made of several hides stitched together, essentially resembling a
Russian fur hat without the flaps.
One of the first pictorial depictions of a hat appears in a tomb painting from
Thebes, Egypt, which shows a man wearing a conical straw hat, dated to around 3200 BC. Hats were commonly worn in ancient Egypt. Many upper-class Egyptians
shaved their heads, then covered it in a
headdress intended to help them keep cool. Ancient Mesopotamians often wore conical hats or ones shaped somewhat like an inverted vase.

Other early hats include the
Pileus, a simple skull-like cap; the
Phrygian cap, worn by freed slaves in Greece and Rome (which became iconic in America during the
Revolutionary War and the
French Revolution, as a symbol of the struggle for liberty against the Monarchy); and the Greek
petasos, the first known hat with a brim. Women wore veils, kerchiefs, hoods, caps and
wimples.
Like Ötzi, the
Tollund Man was preserved to the present day with a hat on, probably having died around 400 BC in a Danish bog, which mummified him. He wore a pointed cap made of sheepskin and wool, fastened under the chin by a hide thong.
St. Clement, the
patron saint of
felt hatmakers, is said to have discovered felt when he filled his sandals with
flax
Flax, also known as common flax or linseed, is a flowering plant, ''Linum usitatissimum'', in the family Linaceae. It is cultivated as a food and fiber crop in regions of the world with temperate climates. In 2022, France produced 75% of t ...

In the Middle Ages, hats were a marker of social status and used to single out certain groups. The 1215
Fourth Council of the Lateran required that all Jews identify themselves by wearing the
Judenhat ("Jewish hat"), marking them as targets for
anti-Semitism. The hats were usually
yellow and were either pointed or square.
In the Middle Ages, hats for women ranged from simple scarves to elaborate
hennin,
[Vibbert, Marie, ''Headdresses of the 14th and 15th Centuries,'' No. 133, SCA monograph series (August 2006)] and denoted social status. Structured hats for women similar to those of male courtiers began to be worn in the late 16th century.
The term 'milliner' comes from the Italian city of
Milan

, where the best quality hats were made in the 18th century. Millinery was traditionally a woman's occupation, with the milliner not only creating hats and bonnets but also choosing lace, trimmings and accessories to complete an outfit.
In the first half of the 19th century, women wore bonnets that gradually became larger, decorated with ribbons, flowers, feathers, and gauze
trims. By the end of the century, many other styles were introduced, among them hats with wide brims and flat crowns, the flower pot and the toque. By the middle of the 1920s, when women began to cut their hair short, they chose hats that hugged the head like a helmet.
The tradition of wearing hats to
horse racing events began at the
Royal Ascot in Britain, which maintains a strict dress code. All guests in the Royal Enclosure must wear hats. This tradition was adopted at other horse racing events, such as the
Kentucky Derby in the United States.

Extravagant hats were popular in the 1980s, and in the early 21st century, flamboyant hats made a comeback, with a new wave of competitive young milliners designing creations that include turban caps,
trompe-l'œil-effect felt hats and tall headpieces made of human hair. Some new hat collections have been described as "wearable sculpture". Many pop stars, among them
Lady Gaga, have commissioned hats as publicity stunts.
Famous hatmakers
One of the most famous London hatters is
James Lock & Co. of
St James's Street. The shop claims to be the oldest operating hat shop in the world. Another was Sharp & Davis of 6
Fish Street Hill. In the late 20th century, museums credited London-based
David Shilling with reinventing hats worldwide. Notable
Belgian hat designers are
Elvis Pompilio and Fabienne Delvigne (
Royal warrant of appointment holder), whose hats are worn by European royals.
Philip Treacy OBE is an Irish milliner whose hats have been commissioned by top designers and worn at royal weddings. In North America, the well-known cowboy-hat manufacturer
Stetson made the headgear for the
Royal Canadian Mounted Police and the
Texas Rangers.
John Cavanagh was one of the notable American hatters. Italian hat maker
Borsalino has covered the heads of Hollywood stars and the world's rich and famous.
Collections
The Philippi Collection is a collection of religious headgear assembled by a German entrepreneur, Dieter Philippi, located in
Kirkel. The collection features over 500 hats, and is currently the world's largest collection of clerical, ecclesiastical and religious head coverings.

Size
Hat sizes are determined by measuring the
circumference
In geometry, the circumference () is the perimeter of a circle or ellipse. The circumference is the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length arou ...
of a person's head about above the ears. Inches or centimeters may be used depending on the manufacturer.
Felt hats can be stretched for a custom fit. Some hats, like
hard hats and
baseball caps, are adjustable. Cheaper hats come in "standard sizes", such as small, medium, large, extra large: the mapping of measured size to the various "standard sizes" varies from maker to maker and style to style, as can be seen by studying various catalogues, such as
Hammacher Schlemmer.
US hat size is a measurement of head diameter in inches. It can be computed from a measurement of circumference in centimeters by dividing by 8, because multiplying 2.54 (the number of centimeters per inch) by (the multiplier to give circumference from diameter) is almost exactly 8.
