ConFurence was the first exclusively furry convention, held annually in southern California from 1989 to 2003. The large furry presence at the BayCon science fiction conventions instigated Mark Merlino and Rod O'Riley to throw "furry parties" at Westercon, Baycon, and other west coast sci-fi conventions in the late 80's. This led to the test gathering in 1989, ConFurence Zero.
