Richard de Clare, 2nd Earl of Pembroke

Richard de Clare (c. 1130 – 20 April 1176), the second Earl of Pembroke, also Lord of Leinster and Justiciar of Ireland (sometimes known as Richard FitzGilbert), was an Anglo-Norman nobleman notable for his leading role in the Anglo-Norman invasion of Ireland. Like his father, Richard is commonly known by his nickname, Strongbow (Anglo-Norman: Arc-Fort).

After his son and heir, Gilbert, died childless before 1189, the earldom passed through Richard's daughter Isabel de Clare and to her husband, William Marshal.
