- January 16, 1922
On January 16, 1922, Michael Collins, on behalf of the new Irish Free State, took over control of Dublin Castle from the British authorities. This event marked a significant milestone in the history of Ireland and the transition from British rule to Irish self-governance.
Dublin Castle had been the center of British administration in Ireland for centuries, and its transfer to Irish control was a symbolic and historic moment. It signified the end of British rule and the beginning of the Irish Free State as a self-governing entity. Michael Collins played a pivotal role in these events, and he became one of the key figures in the early years of the Irish Free State before his tragic assassination later that year.
