Vexillology is the scholarly study of
flags. The term was coined in 1957 by the American scholar
Whitney Smith, the author of many books and articles on the subject. It was originally considered a sub-discipline of
heraldry, and is still occasionally seen as such. It is also sometimes considered a branch of
semiotics.
[1] It is formally defined in the FIAV (
Fédération internationale des associations vexillologiques) constitution as "the creation and development of a body of knowledge about flags of all types, their forms and functions, and of scientific theories and principles based on that knowledge." A person who studies flags is a vexillologist, and by extension, a person who designs flags is a vexillographer.
