The Irish nationalist movement seeks to establish and promote the idea of an independent Ireland, free from British rule. It has roots in the 19th century, with various groups advocating for self-governance and civil rights for the Irish people. Key events, such as the Easter Rising of 1916, played a significant role in galvanizing support for Irish independence. Over the years, the movement has evolved, encompassing a range of political ideologies, from peaceful negotiations to armed struggle. The establishment of Northern Ireland in 1921 created divisions, leading to ongoing tensions between nationalists, who identify as Irish, and unionists, who identify as British.
