Conspiracy '87
From WikiFur, the furry encyclopedia.
Conspiracy '87 was the 45th World Science Fiction Convention in Brighton, England (August 27-September 2, 1987). It was at this convention that first furry room party in the United Kingdom was held. The party was co-hosted by American event organizers Mark Merlino and Rod O'Riley, who had hosted the first "official" furry party at Westercon 39 in San Diego the previous year.
This party was the first-ever recorded furry event in Britain, and is credited by early British furry and funny animal fans as both their own personal introductions to American furry indy comic books and fanzines and the source of the British fandom, which began in 1992-1993 in earnest.
