The Irish Rebellion of 1798 was an uprising against British rule in Ireland. It was led by the United Irishmen, a group that sought to create an independent Irish republic based on democratic principles. The rebellion was fueled by widespread discontent over political and religious discrimination, particularly against Catholics and Dissenters. The rebellion began in May 1798 and involved several battles, but it was ultimately suppressed by British forces. Despite its failure, the uprising highlighted the desire for reform and independence in Ireland, leading to significant political changes, including the eventual union of Great Britain and Ireland in 1801.
