Essex, 1st Earl of at English => English (The Britannica Concise) Of Explained:
English soldier. Born to an English titled family, he helped suppress a rebellion in N England in 1569 and was made earl of Essex in 1572. In 1573 he offered to subdue and colonize, at his own expense, a portion of Ulster that had not accepted English overlordship. There he treacherously captured and executed the Irish rebel leaders and massacred hundreds of the populace, contributing to Irish bitterness toward the English. Elizabeth I commanded him to break off the enterprise in 1575. He died of dysentery shortly after returning to Ireland from England.
