Irish republicanism is a political ideology that advocates for the establishment of a republic in Ireland, free from British rule. It seeks to unite the island of Ireland and promote the rights and identity of the Irish people. This movement has historical roots in the struggle against British colonialism and has evolved over time, influencing various political and social movements. The ideology is often associated with groups like the Irish Republican Army (IRA) and political parties such as Sinn Féin. While some factions have used violence to achieve their goals, others focus on peaceful political processes. The ultimate aim remains the creation of a sovereign and independent Irish state.
