Sir Henry Sidney was an English soldier, politician and Lord Deputy of Ireland.
Shane O'Neill was an Irish chieftain of the O'Neill dynasty of Ulster in the mid-16th century. Shane O'Neill's career was marked by his ambition to be the O'Neill—sovereign of the dominant O'Neill family of Tír Eoghain. This brought him into conflict with competing branches of the O'Neill family and with the English government in Ireland, who recognised a rival claim. Shane's support was considered worth gaining by the English even during the lifetime of his father Conn O'Neill, 1st Earl of Tyrone. But rejecting overtures from the 3rd Earl of Sussex, the lord deputy from 1556, Shane refused to help the English against the Scottish settlers on the coast of Antrim, allying himself for a short time instead with the MacDonnells, the most powerful of these settlers. Shane viewed the Scottish settlers as invaders, but decided to stay his hand against them with hopes of using them to strengthen his position with the English. However, tensions quickly boiled over and he declared war on the Scottish MacDonnell's defeating them at the Battle of Glentaisie despite the MacDonnells calling for reinforcements from Scotland. The Scottish MacDonnells would later assassinate Shane O'Neill and collect the bounty on his head.
Thomas Radclyffe, 3rd Earl of Sussex KG, was Lord Deputy of Ireland during the Tudor period of English history, and a leading courtier during the reign of Elizabeth I.
Baron Inchiquin is one of the older titles in the Peerage of Ireland. It was one of two titles created on 1 July 1543 for Murrough O'Brien, Prince of Thomond, who claimed descent from Brian Boru, a High King of Ireland. The English titles were granted under the policy of surrender and regrant, and therefore conditional upon the abandonment of any Irish titles, the adoption of English customs and laws, pledging of allegiance to the Crown, apostasy from the Catholic Church, and conversion to the Church of Ireland. Murrough was made both Earl of Thomond in the Peerage of Ireland, with remainder to his nephew Donough O'Brien and Baron Inchiquin, with remainder to his male heirs. Following the death of his cousin, Conor Myles John O' Brien in June 2023, Conor John Anthony O' Brien is currently the 19th Baron Inchiquin
Thomond, also known as the Kingdom of Limerick, was a kingdom of Gaelic Ireland, associated geographically with present-day County Clare and County Limerick, as well as parts of County Tipperary around Nenagh and its hinterland. The kingdom represented the core homeland of the Dál gCais people, although there were other Gaels in the area such as the Éile and Eóganachta, and even the Norse of Limerick. It existed from the collapse of the Kingdom of Munster in the 12th century as competition between the Ó Briain and the Mac Cárthaigh led to the schism between Thomond and Desmond. It continued to exist outside of the Anglo-Norman-controlled Lordship of Ireland until the 16th century.
The Dalcassians are a Gaelic Irish clan, generally accepted by contemporary scholarship as being a branch of the Déisi Muman, that became very powerful in Ireland during the 10th century. Their genealogies claimed descent from Tál Cas. Their known ancestors are the subject of The Expulsion of the Déisi tale and one branch of their blood-line went on to rule the petty kingdom of Dyfed in Wales during the 4th century; probably in alliance with the Roman Emperor Magnus Maximus.
Tír Eoghain, also known as Tyrone, was a kingdom and later earldom of Gaelic Ireland, comprising parts of present-day County Tyrone, County Armagh, County Londonderry and County Donegal (Raphoe). The kingdom represented the core homeland of the Cenél nEógain people of the Northern Uí Néill and although they ruled, there were smaller groups of other Gaels in the area. One part of the realm to the north-east broke away and expanded, becoming Clandeboye, ruled by a scion branch of the O'Neill dynasty. In one form or another, Tyrone existed for over a millennium. Its main capital was Dungannon, though kings were inaugurated at Tullyhogue Fort.
Brian O'Neill, also known as Brian "of the battle of Down" O'Neill, was the High King of Ireland from 1258 to 1260.
