Frederick Gordon Brownell OMSS SM and Bar MMM JCD KStJ, D. Phil is a South African herald and genealogist, he designed the flags of South Africa. Brownell was born in Bethlehem, in what was the Orange Free State province in South Africa on 8 March 1940, he matriculated from St. Andrew's School in Bloemfontein in 1957, he undertook his voluntary military service at the Air Force Gymnasium with 1 Motorboat Squadron before going to Rhodes University in Grahamstown to read for a Bachelor of Arts degree in History and Social Anthropology, which he obtained in 1961. He subsequently completed an Honours degree in history at the University of South Africa in 1965 and was awarded a Master of Arts degree from the same university in 1977 for a dissertation entitled "British Immigration to South Africa 1946 – 1970", he married Christine de Villiers, whom he met whilst at Rhodes University, on 29 September 1962 in Pretoria and together they had three daughters. Brownell joined the Department of Immigration on 2 January 1962 as an Administrative Officer.
His responsibilities included a tour of duty as Assistant Attache and Consul to the South African Embassy in London between 1965 and 1969. He joined the Department of National Education / Arts, Culture and Technology as Assistant State Herald in the Bureau of Heraldry on 1 August 1977, he was promoted to State Herald on 1 May 1982 and retired from that position in 2002. Brownell has designed many coats of arms and flags, including the arms and the flag of Namibia in 1990. In 1993/1994, he designed the current South African flag, with a three-armed converging cross of the sort called a pall in heraldry, to symbolise the convergence of different cultures into one for the future South Africa, he designed arms for the new provincial governments in South Africa. He was awarded the Order for Meritorious Service by President Nelson Mandela in 1999 for his role in the design of the South African flag and the Vexillon Award for excellence in the promotion of vexillology in 1995 and 2015, the only recipient to have won it twice.
He has published many articles and several books on heraldry and flags. He has been involved in the field of honours and awards. In September 2015 he was awarded the degree of Doctorate of Philosophy in the Faculty of Humanities at the University of Pretoria for a dissertation entitled Convergence and Unification: The National Flag of South Africa in Historical Perspective, based on the process of, his role in, the designing the current South African flag.

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two sides of equal length, sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, the faces of bipyramids and certain Catalan solids; the mathematical study of isosceles triangles dates back to ancient Egyptian mathematics and Babylonian mathematics. Isosceles triangles have been used as decoration from earlier times, appear in architecture and design, for instance in the pediments and gables of buildings; the two equal sides are called the legs and the third side is called the base of the triangle. The other dimensions of the triangle, such as its height and perimeter, can be calculated by simple formulas from the lengths of the legs and base; every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base.
The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs. Euclid defined an isosceles triangle as a triangle with two equal sides, but modern treatments prefer to define isosceles triangles as having at least two equal sides; the difference between these two definitions is that the modern version makes equilateral triangles a special case of isosceles triangles. A triangle, not isosceles is called scalene. "Isosceles" is a compound word, made from the Greek roots "isos" and "skelos". The same word is used, for instance, for isosceles trapezoids, trapezoids with two equal sides, for isosceles sets, sets of points every three of which form an isosceles triangle. In an isosceles triangle that has two equal sides, the equal sides are called legs and the third side is called the base; the angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
The vertex opposite the base is called the apex. In the equilateral triangle case, since all sides are equal, any side can be called the base. Whether an isosceles triangle is acute, right or obtuse depends only on the angle at its apex. In Euclidean geometry, the base angles cannot be obtuse or right because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right an isosceles triangle is obtuse, right or acute if and only if its apex angle is obtuse, right or acute. In Edwin Abbott's book Flatland, this classification of shapes was used as a satire of social hierarchy: isosceles triangles represented the working class, with acute isosceles triangles higher in the hierarchy than right or obtuse isosceles triangles; as well as the isosceles right triangle, several other specific shapes of isosceles triangles have been studied. These include the Calabi triangle, the golden triangle and golden gnomon, the 80-80-20 triangle appearing in the Langley’s Adventitious Angles puzzle, the 30-30-120 triangle of the triakis triangular tiling.
Five Catalan solids, the triakis tetrahedron, triakis octahedron, tetrakis hexahedron, pentakis dodecahedron, triakis icosahedron, each have isosceles-triangle faces, as do infinitely many pyramids and bipyramids. For any isosceles triangle, the following six line segments coincide: the altitude, a line segment from the apex perpendicular to the base, the angle bisector from the apex to the base, the median from the apex to the midpoint of the base, the perpendicular bisector of the base within the triangle, the segment within the triangle of the unique axis of symmetry of the triangle, the segment within the triangle of the Euler line of the triangle, their common length is the height h of the triangle. If the triangle has equal sides of length a and base of length b, the general triangle formulas for the lengths of these segments all simplify to h = 1 2 4 a 2 − b 2; this formula can be derived from the Pythagorean theorem using the fact that the altitude bisects the base and partitions the isosceles triangle into two congruent right triangles.
The Euler line of any triangle goes through the triangle's orthocenter, its centroid, its circumcenter. In an isosceles triangle with two equal sides, these three points are distinct, all lie on the symmetry axis of the triangle, from which it follows that the Euler line coincides with the axis of symmetry; the incenter of the triangle lies on the Euler line, something, not true for other triangles. If any two of an angle bisector, median, or altitude coincide in a given triangle, that triangle must be isosceles; the area T of an isosceles triangle can be derived from the formula for its height, from the general formula for the area of a triangle as half the product of base and height: T =
White is the lightest color and is achromatic. It is the color of fresh snow and milk, is the opposite of black. White objects reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red and green light. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, Romans wore a white toga as a symbol of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, a white lamb sacrifice and purity, it was the royal color of the Kings of France, of the monarchist movement that opposed the Bolsheviks during the Russian Civil War. Greek and Roman temples were faced with white marble, beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches and other government buildings in the United States, it was widely used in 20th century modern architecture as a symbol of modernity and simplicity. According to surveys in Europe and the United States, white is the color most associated with perfection, the good, cleanliness, the beginning, the new and exactitude.
White is an important color for all world religions. The Pope, the head of the Roman Catholic Church, has worn white since 1566, as a symbol of purity and sacrifice. In Islam, in the Shinto religion of Japan, it is worn by pilgrims. In Western cultures and in Japan, white is the most common color for wedding dresses, symbolizing purity and virginity. In many Asian cultures, white is the color of mourning; the word white continues Old English hwīt from a Common Germanic *χwītaz reflected in OHG wîz, ON hvítr, Goth. ƕeits. The root is from Proto-Indo-European language *kwid-, surviving in Sanskrit śveta "to be white or bright" and Slavonic světŭ "light"; the Icelandic word for white, hvítur, is directly derived from the Old Norse form of the word hvítr. Common Germanic had the word *blankaz, borrowed into Late Latin as *blancus, which provided the source for Romance words for "white"; the antonym of white is black. Some non-European languages have a wide variety of terms for white; the Inuit language has seven different words for seven different nuances of white.
Sanskrit has specific words for bright white, the white of teeth, the white of sandalwood, the white of the autumn moon, the white of silver, the white of cow's milk, the white of pearls, the white of a ray of sunlight, the white of stars. Japanese has six different words, depending upon brilliance or dullness, or if the color is inert or dynamic. White was one of the first colors used in art; the Lascaux Cave in France contains drawings of bulls and other animals drawn by paleolithic artists between 18,000 and 17,000 years ago. Paleolithic artists used calcite or chalk, sometimes as a background, sometimes as a highlight, along with charcoal and red and yellow ochre in their vivid cave paintings. In ancient Egypt, white was connected with the goddess Isis; the priests and priestesses of Isis dressed only in white linen, it was used to wrap mummies. In Greece and other ancient civilizations, white was associated with mother's milk. In Greek mythology, the chief god Zeus was nourished at the breast of the nymph Amalthea.
In the Talmud, milk was one of four sacred substances, along with wine and the rose. The ancient Greeks saw the world in terms of darkness and light, so white was a fundamental color. According to Pliny the Elder in his Natural History and the other famous painters of ancient Greece used only four colors in their paintings. A plain white toga, known as a toga virilis, was worn for ceremonial occasions by all Roman citizens over the age of 14–18. Magistrates and certain priests wore a toga praetexta, with a broad purple stripe. In the time of the Emperor Augustus, no Roman man was allowed to appear in the Roman forum without a toga; the ancient Romans had two words for white. A man who wanted public office in Rome wore a white toga brightened with chalk, called a toga candida, the origin of the word candidate; the Latin word candere meant to be bright. It was the origin of the words candid. In ancient Rome, the priestesses of the goddess Vesta dressed in white linen robes, a white palla or shawl, a white veil.
They protected the penates of Rome. White symbolized their purity and chastity; the early Christian church adopted the Roman symbolism of white as the color of purity and virtue. It became the color worn by priests during Mass, the color worn by monks of the Cistercian Order, under Pope Pius V, a former monk of the Dominican Order, it became the official color worn by the pope himself. Monks of the Order of Saint Benedict dressed in the white or gray of natural undyed wool, but changed to black, the color of humility and penitence. Postclassical history art, the white lamb became the symbol of the sacrifice of Christ on behalf of mankind. John the Baptist described Christ as the lamb of God; the white lamb was the center of one of the most famous paintings of the Medieval period, the Ghent Altarpiece by Jan van Eyck. White was the symbolic color of the transfiguration; the Gospel of Saint Mark describes Jesus' clothing in this event as "shining, exceeding white as snow." Artists such as Fra Angelico used their skill
Green is the color between blue and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of 495–570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, colored green by its chromium content. During post-classical and early modern Europe, green was the color associated with wealth, merchants and the gentry, while red was reserved for the nobility. For this reason, the costume of the Mona Lisa by Leonardo da Vinci and the benches in the British House of Commons are green while those in the House of Lords are red, it has a long historical tradition as the color of Ireland and of Gaelic culture.
It is the historic color of Islam, representing the lush vegetation of Paradise. It was the color of the banner of Muhammad, is found in the flags of nearly all Islamic countries. In surveys made in American and Islamic countries, green is the color most associated with nature, health, spring and envy. In the European Union and the United States, green is sometimes associated with toxicity and poor health, but in China and most of Asia, its associations are positive, as the symbol of fertility and happiness; because of its association with nature, it is the color of the environmental movement. Political groups advocating environmental protection and social justice describe themselves as part of the Green movement, some naming themselves Green parties; this has led to similar campaigns in advertising, as companies have sold green, or environmentally friendly, products. Green is the traditional color of safety and permission; the word green comes from the Middle English and Old English word grene, like the German word grün, has the same root as the words grass and grow.
It is from a Common Germanic *gronja-, reflected in Old Norse grænn, Old High German gruoni from a PIE root *ghre- "to grow", root-cognate with grass and to grow. The first recorded use of the word as a color term in Old English dates to ca. AD 700. Latin with viridis has a genuine and used term for "green". Related to virere "to grow" and ver "spring", it gave rise to words in several Romance languages, French vert, Italian verde; the Slavic languages with zelenъ. Ancient Greek had a term for yellowish, pale green – χλωρός, cognate with χλοερός "verdant" and χλόη "chloe, the green of new growth". Thus, the languages mentioned above have old terms for "green" which are derived from words for fresh, sprouting vegetation. However, comparative linguistics makes clear that these terms were coined independently, over the past few millennia, there is no identifiable single Proto-Indo-European or word for "green". For example, the Slavic zelenъ is cognate with Sanskrit hari "yellow, golden"; the Turkic languages have jašɨl "green" or "yellowish green", compared to a Mongolian word for "meadow".
In some languages, including old Chinese, old Japanese, Vietnamese, the same word can mean either blue or green. The Chinese character 青 has a meaning that covers both green. In more contemporary terms, they are 綠 respectively. Japanese has two terms that refer to the color green, 緑 and グリーン. However, in Japan, although the traffic lights have the same colors as other countries have, the green light is described using the same word as for blue, because green is considered a shade of aoi. Vietnamese uses a single word for both blue and green, with variants such as xanh da trời, lục. "Green" in modern European languages corresponds to about 520–570 nm, but many historical and non-European languages make other choices, e.g. using a term for the range of ca. 450–530 nm and another for ca. 530–590 nm. In the comparative study of color terms in the world's languages, green is only found as a separate category in languages with the developed range of six colors, or more in systems with five colors; these languages have introduced supplementary vocabulary to denote "green", but these terms are recognizable as recent adoptions that are not in origin color terms.
Thus, the Thai word เขียว kheīyw, besides mean
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between green on the spectrum of visible light; the eye perceives blue when observing light with a dominant wavelength between 450 and 495 nanometres. Most blues contain a slight mixture of other colours; the clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called. Distant objects appear. Blue has been an important colour in decoration since ancient times; the semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to white porcelain. In the Middle Ages, European artists used it in the windows of Cathedrals. Europeans wore clothing coloured with the vegetable dye woad until it was replaced by the finer indigo from America.
In the 19th century, synthetic blue dyes and pigments replaced mineral pigments and synthetic dyes. Dark blue became a common colour for military uniforms and in the late 20th century, for business suits; because blue has been associated with harmony, it was chosen as the colour of the flags of the United Nations and the European Union. Surveys in the US and Europe show that blue is the colour most associated with harmony, confidence, infinity, the imagination and sometimes with sadness. In US and European public opinion polls it is the most popular colour, chosen by half of both men and women as their favourite colour; the same surveys showed that blue was the colour most associated with the masculine, just ahead of black, was the colour most associated with intelligence, knowledge and concentration. Blue is the colour of light between green on the visible spectrum. Hues of blue include ultramarine, closer to violet. Blue varies in shade or tint. Darker shades of blue include ultramarine, cobalt blue, navy blue, Prussian blue.
Blue pigments were made from minerals such as lapis lazuli and azurite, blue dyes were made from plants. Today most blue dyes are made by a chemical process; the modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. In heraldry, the word azure is used for blue. In Russian and some other languages, there is no single word for blue, but rather different words for light blue and dark blue. See Colour term. Several languages, including Japanese, Thai and Lakota Sioux, use the same word to describe blue and green. For example, in Vietnamese the colour of both tree leaves and the sky is xanh. In Japanese, the word for blue is used for colours that English speakers would refer to as green, such as the colour of a traffic signal meaning "go". Linguistic research indicates. Colour names developed individually in natural languages beginning with black and white, adding red, only much – as the last main category of colour accepted in a language – adding the colour blue when blue pigments could be manufactured reliably in the culture using that language.
Human eyes perceive blue when observing light which has a dominant wavelength of 450–495 nanometres. Blues with a higher frequency and thus a shorter wavelength look more violet, while those with a lower frequency and a longer wavelength appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. Isaac Newton included blue as one of the seven colours in his first description the visible spectrum, He chose seven colours because, the number of notes in the musical scale, which he believed was related to the optical spectrum, he included indigo, the hue between blue and violet, as one of the separate colours, though today it is considered a hue of blue. In painting and traditional colour theory, blue is one of the three primary colours of pigments, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet and yellow together form green. Mixing all three primary colours together produces a dark grey. From the Renaissance onwards, painters used this system to create their colours.
The RYB model was used for colour printing by Jacob Christoph Le Blon as early as 1725. Printers discovered that more accurate colours could be created by using combinations of magenta, cyan and black ink, put onto separate inked plates and overlaid one at a time onto paper; this method could produce all the colours in the spectrum with reasonable accuracy. In the 19th century the Scottish physicist James Clerk Maxwell found a new way of explaining colours, by the wa
Apartheid was a system of institutionalised racial segregation that existed in South Africa from 1948 until the early 1990s. Apartheid was characterised by an authoritarian political culture based on baasskap, which encouraged state repression of Black African and Asian South Africans for the benefit of the nation's minority white population; the economic legacy and social effects of apartheid continue to the present day. Broadly speaking, apartheid was delineated into petty apartheid, which entailed the segregation of public facilities and social events, grand apartheid, which dictated housing and employment opportunities by race. Prior to the 1940s, some aspects of apartheid had emerged in the form of minority rule by White South Africans and the enforced separation of Black South Africans from other races, which extended to pass laws and land apportionment. Apartheid was adopted as a formal policy by the South African government after the election of the National Party at the 1948 general election.
A codified system of racial stratification began to take form in South Africa under the Dutch Empire in the late-eighteenth century, although informal segregation was present much earlier due to social cleavages between Dutch colonists and a creolised, ethnically diverse slave population. With the rapid growth and industrialisation of the British Cape Colony in the nineteenth century, racial policies and laws became rigid. Cape legislation that discriminated against Black South Africans began appearing shortly before 1900; the policies of the Boer republics were racially exclusive. The first apartheid law was the Prohibition of Mixed Marriages Act, 1949, followed by the Immorality Amendment Act of 1950, which made it illegal for most South African citizens to marry or pursue sexual relationships across racial lines; the Population Registration Act, 1950 classified all South Africans into one of four racial groups based on appearance, known ancestry, socioeconomic status, cultural lifestyle: "Black", "White", "Coloured", "Indian", the last two of which included several sub-classifications.
Places of residence were determined by racial classification. From 1960–1983, 3.5 million Non-White South Africans were removed from their homes and forced into segregated neighbourhoods, in one of the largest mass evictions in modern history. Most of these targeted removals were intended to restrict the Black population to ten designated "tribal homelands" known as bantustans, four of which became nominally independent states; the government announced that relocated persons would lose their South African citizenship as they were absorbed into the bantustans. Apartheid sparked significant international and domestic opposition, resulting in some of the most influential global social movements of the twentieth century, it was the target of frequent condemnation in the United Nations and brought about an extensive arms and trade embargo on South Africa. During the 1970s and 1980s, internal resistance to apartheid became militant, prompting brutal crackdowns by the National Party government and protracted sectarian violence that left thousands dead or in detention.
Some reforms of the apartheid system were undertaken, including allowing for Indian and Coloured political representation in parliament, but these measures failed to appease most activist groups. Between 1987 and 1993, the National Party entered into bilateral negotiations with the African National Congress, the leading anti-apartheid political movement, for ending segregation and introducing majority rule. In 1990, prominent ANC figures such as Nelson Mandela were released from prison. Apartheid legislation was repealed on 17 June 1991, pending democratic, multiracial elections set for April 1994. Apartheid is an Afrikaans word meaning "separateness", or "the state of being apart" "apart-hood", its first recorded use was in 1929. Under the 1806 Cape Articles of Capitulation the new British colonial rulers were required to respect previous legislation enacted under Roman Dutch law and this led to a separation of the law in South Africa from English Common Law and a high degree of legislative autonomy.
The governors and assemblies that governed the legal process in the various colonies of South Africa were launched on a different and independent legislative path from the rest of the British Empire. In the days of slavery, slaves required passes to travel away from their masters. In 1797 the Landdrost and Heemraden of Swellendam and Graaff-Reinet extended pass laws beyond slaves and ordained that all Khoikhoi moving about the country for any purpose should carry passes; this was confirmed by the British Colonial government in 1809 by the Hottentot Proclamation, which decreed that if a Khoikhoi were to move they would need a pass from their master or a local official. Ordinance No. 49 of 1828 decreed that prospective black immigrants were to be granted passes for the sole purpose of seeking work. These passes were to be issued for Coloureds and Khoikhoi, but not for other Africans, who were still forced to carry passes; the United Kingdom's Slavery Abolition Act 1833 abolished slavery throughout the British Empire and overrode the Cape Articles of Capitulation.
To comply with the act the South African legislation was expanded to include Ordinance 1 in 1835, which changed the status of slaves to indentured labourers. This was followed by Ordinance 3 in 1848, which introduced an indenture system for Xhosa, little different from slave
A national flag is a flag that represents and symbolizes a country. The national flag is flown by the government of a country, but can also be flown by citizens of the country. A national flag is designed with specific meanings for its symbols; the colours of the national flag may be worn by the people of a nation to show their patriotism, or related paraphernalia that show the symbols or colours of the flag may be used for those purposes. The design of a national flag may be altered after the occurrence of important historical events; the burning or destruction of a national flag is a symbolic act. Flags originate as military standards, used as field signs; the practice of flying flags indicating the country of origin outside of the context of warfare became common with the maritime flag, introduced during the age of sail, in the early 17th century. The origins of the Union Jack flag date back to 1603, when James VI of Scotland inherited the English and Irish thrones, thereby uniting the crowns of England and Ireland in a personal union.
On 12 April 1606, a new flag to represent this regal union between England and Scotland was specified in a royal decree, according to which the flag of England, the flag of Scotland, would be joined together, forming the flag of Great Britain and first Union Flag. With the emergence of nationalist sentiment from the late 18th century national flags began to be displayed in civilian contexts as well. Notable early examples include the US flag, first adopted as a naval ensign in 1777 but began to be displayed as a generic symbol of the United States after the American Revolution, the French Tricolore, which became a symbol of the Republic in the 1790s. Most countries of Europe adopted a national flag in the course of the 19th and early 20th centuries based on older war flags; the specifications of the flag of Denmark were codified based on a 14th-century design. The flag of Switzerland was introduced in 1889 based on medieval war flags; the Netherlands introduced two national flags in 1813. The Ottoman flag was adopted in 1844.
Other non-European powers followed the trend in the late 19th century, the flag of Japan being introduced in 1870, that of Qing China in 1890. In the 19th century, most countries of South America introduced a flag as they became independent The national flag is but not always, mentioned or described in a country's constitution, but its detailed description may be delegated to a flag law passed by the legislative, or secondary legislation or in monarchies a decree. Thus, the national flag is mentioned in the Basic Law for the Federal Republic of Germany of 1949 "the federal flag is black-red-gold", but its proportions were regulated in a document passed by the government in the following year; the Flag of the United States is not defined in the constitution but rather in a separate Flag Resolution passed in 1777. Minor design changes of national flags are passed on a legislative or executive level, while substantial changes have constitutional character; the design of the flag of Serbia omitting the communist star of the flag of Yugoslavia was a decision made in the 1992 Serbian constitutional referendum, but the adoption of a coat of arms within the flag was based on a government "recommendation" in 2003, adopted legislatively in 2009 and again subject to a minor design change in 2010.
The Flag of the United States underwent numerous changes because the number of stars represents the number of states, proactively defined in a Flag Act of 1818 to the effect that "on the admission of every new state into the Union, one star be added to the union of the flag". A change in national flag is due to a change of regime following a civil war or revolution. In such cases, the military origins of the national flag and its connection to political ideology remains visible. In such cases national flags acquire the status of a political symbol; the flag of Germany, for instance, was a tricolour of black-white-red under the German Empire, inherited from the North German Confederation. The Weimar Republic that followed adopted a black-red-gold tricolour. Nazi Germany went back to black-white-red in 1933, black-red-gold was reinstituted by the two successor states, West Germany and East Germany following World War II; the flag of Libya introduced with the creation of the Kingdom of Libya in 1951 was abandoned in 1969 with the coup d'état led by Muammar Gaddafi.
It was used again by National Transitional Council and by anti-Gaddafi forces during the Libyan Civil War in 2011 and adopted by the Libyan interim Constitutional Declaration. There are three distinct types of national flag for use on land, three for use at sea, though many countries use identical designs for several of these types of flag. On land, there is a distinction between civil flags, state flags, war or military flags. Civil flags may be flown by anyone regardless of whether they are linked to government, whereas state flags are those used by government agencies. War flags are used by military organizations such as Armies, Marine Corp
