The event was established in 1921, a year before the launch of the Irish 1,000 Guineas. The inaugural running was won by Soldennis.
It is Ireland's equivalent of the 2,000 Guineas, and in recent years it has taken place three weeks after that race. The field usually includes horses which previously contested the English version, and nine have achieved victory in both events. The first was Right Tack in 1969, and the most recent was Churchill in 2017.
The leading horses from the Irish 2,000 Guineas often go on to compete in the following month's St. James's Palace Stakes. The most recent to win both races was Paddington in 2023.
