Irish Nationalists are individuals or groups who advocate for the political and cultural independence of Ireland from British rule. They seek to promote the idea of a united Ireland, where both the Republic of Ireland and Northern Ireland are governed as one entity, free from external control. The movement has a long history, with roots in the 19th century and significant events like the Easter Rising of 1916. Irish Nationalists often emphasize the importance of Irish culture, language, and identity, aiming to preserve and promote these elements in the face of historical oppression.
