On December 10, 1921, the Dáil Éireann began intense and often acrimonious debates over the recently signed Anglo-Irish Treaty. This treaty proposed the establishment of the Irish Free State but required an oath of allegiance to the British Crown and partitioned the island. Key figures like Michael Collins, who supported the treaty as a stepping stone to full independence, and Cathal Brugha, who vehemently opposed it due to the oath and partition, engaged in heated exchanges. These discussions exposed deep ideological divisions within the Irish nationalist movement, ultimately leading to the tragic Irish Civil War in 1922-1923. The debates were crucial in shaping the political landscape of independent Ireland.
