On September 12, 1919, the British government officially declared Dáil Éireann an illegal assembly, forcing the nascent Irish parliament to operate in secrecy. This proclamation marked a significant escalation in the conflict between Irish nationalists and British authorities during the Irish War of Independence. Despite the ban, the Dáil continued to function underground, maintaining its republican government structures and issuing decrees, thereby challenging British rule and solidifying its legitimacy among a substantial portion of the Irish population. The suppression inadvertently strengthened the resolve of the independence movement, leading to further confrontation and ultimately contributing to the intensification of the struggle for Irish self-determination.
