competition began with 32 clubs in a straight knock-out format in February 1987, and included teams from the Irish League B Division until 1997–98. From 1998–99 until 2007–08, only senior (Irish League and Irish Premier League) teams competed, but the competition was opened up to the 17 Championship clubs in 2008–09, and again in 2010–11 to include clubs from Championship 2, after the Championship 2 League Cup was abolished. From 2001–02 until 2007–08, a group stage followed by a knock-out system was used instead of the straight knock-out system, and for two seasons (2008–09 and 2009–10) two-legged home and away aggregate ties were used up until the quarter-finals, instead of single matches. When it was first introduced in the 1986–87 season, it was one of a number of senior cup competitions run by the Irish League, originally to compensate for the relatively few league fixtures (traditionally 22 or 26), but also as vehicles for sponsorship revenue.

The first final took place on 9 May 1987 at Glentoran's ground, the Oval, and was contested by Linfield and Crusaders. Linfield became the inaugural winners of the cup, defeating Crusaders 2–1. Since then, Linfield have been the most successful club in the competition, winning the Cup a record 10 times overall in a record 13 final appearances - their three final defeats all coming against Big Two rivals Glentoran. The most common final has indeed been the Big Two derby, which has occurred seven times - the last of which came in 2005–06. The 1988–89 final, played between the two sides at the Oval on 11 November 1988 was won courtesy of a goal by Glentoran goalkeeper Alan Patterson, via a kick from his own penalty area. This was the first time that a goalkeeper had ever scored in a British
