Richard Strongbow, also known as Richard de Clare, was a prominent Anglo-Norman lord in the 12th century. He is best known for his role in the Norman invasion of Ireland and for leading the conquest of parts of Ireland, particularly the province of Leinster. Strongbow was born around 1130 and became the Earl of Pembroke, gaining significant power and influence through his military exploits. In 1170, Strongbow married Aoife, the daughter of the King of Leinster, which solidified his claim to the region. His actions laid the groundwork for the establishment of English rule in Ireland, significantly impacting the island's history. Strongbow died in 1176, leaving a legacy that shaped the future of Anglo-Irish relations.
