The Societas Caucasologica Europaea organized biennial meetings on Caucasian linguistics and literature for about 20 years. More details can be found here.
The biennial meetings commenced in 1983 (Hull, England). Subsequent meetings were held in 1984 (Vienna, Austria), 1986 (Oslo, Norway, when the society was formally constituted), 1988 (Paris, France), 1990 (London, England), 1992 (Maikop, Adygheian Republic, Russian Federation), 1994 (Marburg, Germany), 1996 (Leiden, Holland), 2000 (Munich, Germany), 2002 Moscow (Russian Federation). Since then the society has been inactive.
Proceedings of the meetings were published locally:
