East Anglia is a geographical region located in the east of England. Within the wizarding world, it is known, at least to some, as a destination for holidays or casual trips, referred to as “jaunts.” Its history within the magical community is not detailed in the series, but it is evidently a familiar location to wizards and witches living in Britain, co-existing within the known Muggle geography.
East Anglia's sole mention in the series occurs in Harry Potter and the Goblet of Fire during the 1994 Quidditch World Cup. While providing commentary on the match between Ireland and Bulgaria, Ludo Bagman, the Head of the Department of Magical Games and Sports, publicly dismisses the seriousness of Ministry of Magic employee Bertha Jorkins's disappearance. When discussing that Bertha Jorkins was last seen in Albania, Bagman attempts to downplay concerns by comparing her absence to a casual holiday, remarking, “Went on a bit of a jaunt to East Anglia once, myself.” He uses this personal anecdote to frivolously suggest that Jorkins might simply be on a similar trip and will return eventually. This comment primarily serves to characterize Ludo Bagman as careless and irresponsible, highlighting the Ministry of Magic's initial failure to properly investigate her disappearance, which was in fact a kidnapping by Peter Pettigrew that led directly to her murder by Lord Voldemort.
