IWCCW Heavyweight Championship
The ICW / IWCCW Heavyweight Championship was the top singles championship of International World Class Championship Wrestling between 1984 and 1995 where IWCCW closed down operations. Since the ICW/IWCCW championships were not given "world title status" by Pro Wrestling Illustrated, this championship was seen as a regional championship, although it was considered the top singles championship of the promotion.
Initially ICW’s main title was the WWC Universal Heavyweight Championship, through a talent exchange program and a close working relationship between ICW and WWC the Universal Title was promoted in the New England area as the main ICW title without ever mentioning the WWC name, nor was it presented as a title owned by ICW. When the arrangement came to an end in 1985 a specific “ICW Heavyweight Championship” was created with the lineage of the WWC Universal title during the time of the working relationship.
In 1993 the then champion Tony Atlas along with a number of IWCCW wrestlers left the company leaving the title vacant and only used sporadically between 1993 and 1995 where the promotion closed.
