A coven or covan is a gathering of witches. The word derives from a word found in 1300 in the Old French "covenant" meaning an agreement from the Latin "convenire" meaning "to agree", and so from that to a late medieval Scots word (circa 1500) meaning a gathering of any kind, according to the Oxford English Dictionary. The Latin root word convenire also means to come together or to gather, which also gave rise to the English word convene and to "convent". The first recorded use of "coven" as applied to an order of witches comes much later, from 1662 in the witch-trial of Isobel Gowdie, which describes a coven of 13 members.
The word coven remained largely unused in English until 1921 when Margaret Murray promoted the idea, now much disputed, that all witches across Europe met in groups of thirteen which they called "covens".
In Wicca and other similar forms of modern neopagan witchcraft, such as Stregheria and Feri Witchcraft, a coven is a gathering or community of witches, much like a congregation in Christian parlance. It is composed of a group of believers who gather together for ceremonies of worship such as Drawing Down the Moon, or celebrating the Sabbats. The number of persons involved may vary. Although thirteen is considered ideal (probably in deference to Murray's theories), any group of at least three can be a coven. A group of two is usually called a "working couple" (regardless of their sexes). Within the community, many believe that a coven larger than thirteen is unwieldy, citing unwieldy group dynamics and an unfair burden on the leadership. When a coven has grown too large to be manageable, it may split, or "hive". In Wicca this may also occur when a newly made High Priest or High Priestess, also called 3rd Degree ordination, leaves to start their own coven. Wiccan covens are generally jointly led by a High Priestess and a High Priest, though some are led by only one or the other. In more recent forms of neopagan witchcraft, covens are sometimes run as democracies with a rotating leadership.
Online covens 
With the rise of the World Wide Web as a platform for collaborative discussion and media dissemination, it became popular for adherents and practitioners of Wicca to establish (often paid subscription-based) "online covens" which remotely teach tradition-specific crafts to students in a similar method of education as non-religious virtual online schools.
However, because of potentially-unwieldy membership sizes, many online covens limit their memberships to anywhere between 10 to 100 students. The CFFN, in particular, tried to devolve its structure into a system of sub-coven clans (which governed their own application processes), a system which ended in 2003 due to fears by the CFFN leadership that the clans were becoming communities in their own right.
Usage in literature and popular culture 
In fantasy stories and popular culture, a coven is a gathering of witches to work spells in tandem. Such imagery can be traced back to Renaissance prints depicting witches and to the three "weird sisters" in Shakespeare's play Macbeth. More orgiastic witches' meetings are also depicted in Robert Burns' poem "Tam o' Shanter" and in Goethe's play Faust. Movie portrayals have included, for example, Suspiria, Rosemary's Baby, The Covenant, Underworld and Underworld: Evolution, The Craft, Coven and Paranormal Activity 3. In television, covens were portrayed in the U.S. supernatural drama Charmed and the HBO series True Blood.
