Connacht Rugby and Ulster Rugby are two Irish rugby union provincial teams that possess a rivalry that dates back to their IRFU Interprovincial Championship clashes during the amateur era. That rivalry has continued during the professional era and intensified as Connacht have more competitive in the domestic league, winning 2015-16 Pro12 championship. Connacht and Ulster comprise two of the four Irish provincial teams competing in the United Rugby Championship (formerly known as the Celtic League). As such, the two sides regularly face each other during the regular season. Typically, Ulster have had the advantage in the series with Connacht failing to achieve a single victory over Ulster between 1965 and 1982. Following Connacht's victory in 1983, it would not be until the 1997âÂÂ98 season until they would achieve their next victory over Ulster. Connacht also went 58 years without winning a match in Belfast.
