Shane O’Neill, Irish patriot known by the nickname “Shane the Proud,” is murdered in what is now Cushendum, County Antrim, Northern Ireland on June 2, 1567. He is among the most famous of all the O’Neills.
O’Neill, the eldest legitimate son of Conn O’Neill, 1st Earl of Tyrone, is a chieftain whose support the English consider worth gaining. However, he rejects overtures from Thomas Radclyffe, 3rd Earl of Sussex, the Lord Deputy of Ireland, and refuses to help the English against the Scottish settlers on the coast of Antrim. He allies himself instead with the MacDonnells, the most powerful of these immigrants. Nevertheless, Queen Elizabeth I of England is disposed to come to terms with O’Neill who, after his father’s death, is de facto chief of the O’Neill clan. She recognizes his claims to the chieftainship, thus throwing over a kinsman, Brian O’Neill. O’Neill, however, refuses to put himself in the power of Sussex without a guarantee for his safety and his claims are so exacting that Elizabeth determines to restore Brian. An attempt to incite the O’Donnells against him, however, is frustrated.
Elizabeth, who is not prepared to undertake the subjugation of the Irish chieftain, urgently desires peace with O’Neill, especially when the devastation of his territory by Sussex brings him no nearer to submission. Sussex is not supported by the queen, who sends Gerald FitzGerald, 11th Earl of Kildare to arrange terms with O’Neill. The latter agrees to present himself before Elizabeth. Accompanied by Thomas Butler, 10th Earl of Ormonde and Kildare, he reaches London on January 4, 1562. Elizabeth temporizes but, finding that O’Neill is in danger of becoming a tool in the hands of Spanish intriguers, permits him to return to Ireland, recognizing him as “the O’Neill,” and chieftain of Tyrone.
There are at this time three powerful contemporary members of the O’Neill family in Ireland — O’Neill, Turlough Luineach O’Neill, and Matthew Ó Néill, 1st Baron Dungannon. Turlough had schemed to supplant O’Neill during his absence in London. The feud does not long survive O’Neill’s return to Ireland, where he reestablishes his authority and renews his turbulent tribal warfare. Elizabeth at last authorizes Sussex to take the field against O’Neill, but two expeditions fail. O’Neill then lays the entire blame for his lawless conduct on the lord deputy’s repeated alleged attempts on his life. Elizabeth consents to negotiate, and practically all of O’Neill’s demands are conceded.
O’Neill then turns his hand against the MacDonnells, claiming that he is serving the Queen of England in harrying the Scots. He fights an indecisive battle with Sorley Boy MacDonnell near Coleraine in 1564, and in 1565 he routs the MacDonnells and takes Sorley Boy prisoner near Ballycastle. This victory strengthens O’Neill’s position, but the English make preparations for his subjugation.
Failing in an attempt to arrange terms, and also in obtaining the help which he solicited from France, O’Neill is utterly routed by the O’Donnells at the Battle of Farsetmore near Letterkenny and, seeking safety in flight, throws himself on the mercy of his enemies, the MacDonnells. Attended by a small body of gallowglass, and taking his prisoner Sorley Boy with him, he presents himself among the MacDonnells near Cushendun, on the Antrim coast, hoping to propose an alliance. Here, on June 2, 1567, he is killed by the MacDonnells and his headless body is buried at Crosskern Church at Ballyterrim above Cushendun. His body is possibly later moved to Glenarm Abbey. Unbeknownst to O’Neill, The Scots had already come to an agreement with Henry Sidney and William Piers, Seneschal of Clandeboye, commander of the English garrison at Carrickfergus. The English Government tries to pass this off as a “drunken brawl” turned savage. Piers travels to Cushendun to take O’Neill’s head and send it to Dublin Castle.
