Kilkenny in the context of "Kilkenny County Council"

County Kilkenny (Irish: Contae Chill Chainnigh) is a county in Ireland. It is in the province of Leinster and is part of the Southern Region. It is named after the city of Kilkenny. Kilkenny County Council is the local authority for the county. At the 2022 census the population of the county was 103,685. The county was based on the historic Gaelic kingdom of Ossory (Osraighe), which was coterminous with the Diocese of Ossory.

The Diocese of Ossory (Latin: Dioecesis Ossoriensis; Irish: Deoise Osraí) is a Latin Church diocese of the Catholic Church in eastern Ireland. It is one of three suffragan dioceses in the ecclesiastical province of the Metropolitan Archbishop of Dublin and has been led by Niall Coll since 2023.

The Cathedral church is St. Mary of the Assumption, in Kilkenny.

Máel Sechnaill mac Máel Ruanaida (Modern Irish: Maolsheachlann Mac Maolruanaidh), also known as Máel Sechnaill I, anglicised as Malachy MacMulrooney (died 27 November 862) was High King of Ireland. The Annals of Ulster use the Old Irish title rí hÉrenn uile, that is "king of all Ireland", when reporting his death, distinguishing Máel Sechnaill from the usual Kings of Tara who are only called High Kings of Ireland in late sources such as the Annals of the Four Masters or Geoffrey Keating's Foras Feasa ar Éirinn. According to the "Grand History of the Celts", a traditional book of facts and folklore, Mael Sechnaill was the husband of Mael Muire and Land ingen Dúngaile, the granddaughter of the legendary Alpin, a 9th-century king of Dalriada.

Confederate Ireland, also referred to as the Irish Catholic Confederation, was a period of Irish Catholic self-government between 1642 and 1652, during the Eleven Years' War. Formed by Catholic aristocrats, landed gentry, clergy and military leaders after the Irish Rebellion of 1641, the Confederates controlled up to two-thirds of Ireland from their base in Kilkenny; hence it is sometimes called the Confederation of Kilkenny.

The Confederates included Catholics of Gaelic and Anglo-Norman descent. They wanted an end to anti-Catholic discrimination within the Kingdom of Ireland and greater Irish self-governance; many also wanted to roll back the plantations of Ireland. Most Confederates professed loyalty to Charles I of England in the belief they could reach a lasting settlement in return for helping defeat his opponents in the Wars of the Three Kingdoms. Its institutions included a legislative body known as the General Assembly, an executive or Supreme Council, and a military. It minted coins, levied taxes and set up a printing press. Confederate ambassadors were appointed and recognised in France, Spain and the Papal States, who supplied them with money and weapons.

Owen Roe O'Neill (Irish: Eoghan Ruadh Ó Néill; c. 1585 – 6 November 1649) was a Gaelic Irish soldier and one of the most famous of the O'Neill dynasty of Ulster. O'Neill left Ireland at a young age and spent most of his life as a mercenary in the Spanish Army serving against the Dutch in Flanders during the Eighty Years' War. After the Irish Rebellion of 1641, O'Neill returned and took command of the Irish Confederate Ulster Army. He is known for his victory at the Battle of Benburb in 1646.

O'Neill's later years were marked by infighting amongst the Confederates, and in 1647 he led his army to seize power in the capital of Kilkenny. His troops clashed with rival forces of the Confederacy, leading to O'Neill forming a temporary alliance with Charles Coote's English Parliamentary forces in Ulster. He initially rejected a treaty of alliance between the Confederates and the Irish Royalists, but faced with the Cromwellian invasion he changed his mind. O'Neill died shortly after agreeing to an alliance with the 1st Marquess of Ormond, the Lord Lieutenant of Ireland. The agreement included the promise of an Earldom, but O'Neill died on Tuesday, 6 November 1649.
