May 1, 1170 — Strongbow and the English invade Ireland. When Diarmuid MacMurrough, King of Leinster, was banished, he sought refuge in England, where he sought the aid of King Henry. The King gave him letters authorizing any of his subjects to go to Ireland who wished. Richard de Clare or Strongbow was a bold and daring warrior, and MacMurrough promised him his daughter in marriage in exchange for his help. With an efficient body of knights and archers, they invaded Ireland, quickly capturing Wexford, Waterford and Dublin. And as they say, “the rest is history.”
