History
When the Connacht Senior League was established in 1981–82 the organisers also introduced two league cup competitions. Mervue United defeated Sligo Rovers Reserves in the final of the inaugural League Cup, a pre-season competition featuring two legs per round. In 1988–89 this competition was renamed the League Shield. The second cup competition was the Connacht Senior League Challenge Cup. This was played at the end of the season. Mervue United were the inaugural winners and went on to win it four times in a row. In 1982–83 a third cup, the Incentive Cup, was introduced. It initially featured the two most improved sides who had failed to win another trophy. Tuam Celtic were the first winners. In 1989–90 the format was changed to include teams knocked out in the first round of the Challenge Cup. Castlebar Celtic became the first winners under the new format. Connacht Senior League teams also played in the separate Connacht Senior Cup which also featured teams from the four junior leagues based in the province – the Galway & District League, the Sligo-Leitrim League, the Mayo Association Football League and the Roscommon & District League. In 1994–95 when the Connacht Senior League was split into two groups the competition did not take place. In 1995–96 when the league featured two divisions there was also two league cups, the Premiership Cup and the First Division Cup. When the two divisions were scrapped after one season, the Premiership Cup name was retained.
