Vexillology is the scientific term for the study of flags of all kinds, modern and historical. It seeks to establish a body of practice for flag design and usage; to create a body of theory of flag development; and to understand and explain the important role of flags in the modern world. The word is derived from the Latin vexillum, a Roman standard composed of a fabric hung from a horizontal crossbar on a pole. The vexillum is the closest equivalent in the classical world to what today is called a flag.
Every two years, vexillologists worldwide meet to share information, opinion and ideas at the International Congress of Vexillology (ICV). The first ICV was held in Muiderberg (The Netherlands) in 1965, and since 1969 the congress has taken place under the auspices of the International Federation of Vexillological Assocations / Fédération internationale des associations vexillologiques (FIAV).
The Flag Institute has hosted the ICV on three occasions: ICV5 (London, 1973), ICV19 (York, 2001) and ICV27 (London, 2017). The Flag Institute also assisted the Heraldry Society as host of ICV10 (Oxford, 1983).
