The GAA, or Gaelic Athletic Association, is an organization that promotes traditional Irish sports, including Gaelic football and hurling. Ireland is divided into four main provinces: Leinster, Munster, Connacht, and Ulster. Each province has its own teams and competitions, contributing to the rich sporting culture in the country. Each province hosts its own championship, culminating in the GAA All-Ireland Championships. These championships allow teams from different provinces to compete for the title of the best in Ireland. The provincial structure helps to foster local rivalries and showcases the unique traditions of each region.
