The Tudor Conquest refers to the period during the late 15th and early 16th centuries when the Tudor dynasty sought to expand its influence in Ireland. This effort was marked by military campaigns and political maneuvers aimed at establishing English control over the island, which had a complex landscape of local chieftains and clans. Key figures in this conquest included Henry VIII, who initiated policies to assert English authority, and Elizabeth I, who continued these efforts. The conquest led to significant changes in governance and land ownership, ultimately shaping the relationship between England and Ireland for centuries to come.
