Gaelic Sunday, held on August 4, 1918, was a significant act of defiance by the Gaelic Athletic Association (GAA) against British rule in Ireland. The British authorities had introduced a permit system requiring official permission for sporting events. In response, the GAA organized a nationwide protest where thousands of people participated in Gaelic games across Ireland without permits. This mass demonstration, involving an estimated 1,800 games, asserted Irish cultural identity and resistance to British attempts to suppress nationalist activities during a period of heightened political tension.
