Canton (flag)


A canton in a flag is a rectangular area, usually at the top hoist corner of a flag, occupying up to a quarter of the flag's area. The canton of a flag may be a flag in its own right. For instance, British ensigns have the Union Jack as their canton, as do their derivatives such as the national flags of Australia and New Zealand.
Following the practice of British ensigns, a canton sometimes contains a symbol of national unity, such as the blue field and white stars of the American flag. In these cases, the canton may be called simply the union.
The American flag's canton derives from Britain's use of the Union Jack in the flags of its possessions. Subsequently, many New World nations that were inspired by the United States adopted flag elements that were inspired by the American flag. As a result, many extant uses of a prominent canton derive either from British territorial history, or American influence and inspiration.
