What is a flag?
A piece of cloth, varying in size, shape, color, and design, usually attached at one edge to a staff or cord, and used as the symbol of a nation, state, or organization, as a means of signaling, ensign; standard; banner; pennant.

Flags through the Centuries
Although flag-like symbols have been used by ancient cultures for thousands of years, the origin of flags in the modern sense is a matter of dispute. Some believe flags originated in China, while others hold that the Roman Empire's vexillum was the first true flag. Originally, the standards of the Roman legions were not flags, but symbols like the eagle of Augustus Caesar's Xth legion; this eagle would be placed on a staff for the standard-bearer to hold up during battle. But a military unit from Scythia had for a standard a dragon with a flexible tail which would move in the wind; the legions copied this; eventually all the legions had flexible standards — our modern-day flag.

From the time of Christopher Columbus onwards, it has been customary (and later a legal requirement) for ships to carry flags designating their nationality; these flags eventually evolved into the national flags and maritime flags of today. Flags also became the preferred means of communications at sea, resulting in various systems of flag signals; see code flags

Beginning in the 17th century, European knights were replaced by centralized armies, and flags became the means to identify not just nationalities but also individual military units. Flags became much more elaborate, and were seen as objects to be captured or defended. Eventually these flags posed too much danger to those carrying them, and by World War I these were withdrawn from the battlefields, and have since been used only at ceremonial occasions.

Shape and Design
Flags are usually rectangular in shape, but may be of any shape or size that is practical for flying. Named shapes include square (e.g., the national flag of Switzerland and the state flag of the Vatican City), pennant, double pennant (e.g., the state flag of Ohio), swallowtail, triangular or swallowtail burgee, gonfanon and oriflamme. A more unusual flag shape is that of the flag of Nepal, which is in the shape of two stacked triangles.


There are even six flags on the moon planted by the Apollo astronauts. You would require a telescope around 200 meters in diameter to see them.

History of the South African Flag
After the Anglo-Boer War from 1899 to 1902 and the formation of the Union of South Africa in 1910, the British Union Flag became the national flag of South Africa. As was the case throughout the British Empire, the Red and Blue Ensign with the Union coat of arms were granted by British Admiralty warrants in 1910 for use at sea.

These ensigns were not intended to be used as the Union's national flag, although they were used by some people as such, especially the Red Ensign. It was only after the first post-Union Afrikaner government took office in 1925 that a bill was introduced in Parliament to make provisions for a national flag for the Union; this action immediately prompted three years of near civil war, as the British thought that the Boers wanted to remove their cherished imperial symbols. Natal Province even threatened to secede from the Union.
