The Irish Rebellion of 1641 was a major uprising by Irish Catholics against English rule in Ireland. It began in October 1641, driven by grievances over land confiscations and religious discrimination. The rebels aimed to gain control of Ireland and restore Catholic rights, leading to widespread violence and conflict. The rebellion quickly escalated, resulting in brutal clashes and significant loss of life. It marked the beginning of a series of conflicts known as the Wars of the Three Kingdoms, which included the English Civil War. The rebellion ultimately failed to achieve its goals, leading to further oppression of Catholics in Ireland.
