 However, in the Republic of Ireland the now defunct League of Ireland Shield was the first national league-only tournament of its kind; this was subsequently replaced by the League of Ireland Cup in 1983.The creation of a League Cup marked the difference from the or Primary Cup, which is generally also open to teams from multiple leagues, often as far down as regional amateur leagues, and who are also members of the country's football association.The creation of a tournament of this kind exclusively for the top national-level league teams, in addition to the two main domestic association football tournaments of the league and association cup, also created a new national footballing achievement called the domestic "treble".
