What originated as the seed of an idea for an event to celebrate and promote Irish heritage, Irish Festivals Inc. has emerged into a thriving organization that celebrates the music, culture and history of Ireland during its four-day festival as well as several outreach initiatives throughout the year.

In the early 1980s, members of Milwaukee's Irish community gathered to discuss opportunities to promote their Gaelic heritage in a city known for its German roots. The idea of a festival, a three-day event to promote Irish culture through music, dance, cultural exhibits, drama and sports, was born. The festival wasn't just an opportunity to feature national Irish acts but also an impetus to showcase local groups that celebrate the rich traditions of Irish music.

Under the direction of Ed Ward, the first Irish Fest premiered in 1981 on a shoestring budget. Volunteers spent months planning the event, incorporating an extensive lineup of musical entertainment and cultural programming. Based on the event's success and overwhelming interest by those in attendance, the Smithsonian Institution's National Folk Life program called Milwaukee Irish Fest "the largest and best Irish cultural event in North America."
