The history of Ireland from 1169–1536 covers the period from the arrival of the Cambro-Normans to the reign of Henry II of England, who made his son, Prince John, Lord of Ireland. After the Norman invasions of 1169 and 1171, Ireland was under an alternating level of control from Norman lords and the King of England. Previously, Ireland had seen intermittent warfare between provincial kingdoms over the position of High King. This situation was transformed by intervention in these conflicts by Norman mercenaries and later the English crown. After their successful conquest of England, the Normans turned their attention to Ireland. Ireland was made a Lordship of the King of England and much of its land was seized by Norman barons. With time, Hiberno-Norman rule shrank to a territory known as the Pale, stretching from Dublin to Dundalk. The Hiberno-Norman lords elsewhere in the country became Gaelicised and integrated in Gaelic society.

The Lordship of Ireland, sometimes referred to retroactively as Norman Ireland, was the part of Ireland ruled by the King of England and controlled by loyal Anglo-Norman lords between 1177 and 1542. The lordship was created following the Norman invasion of Ireland in 1169–1171. It was a papal fief, granted to the Plantagenet kings of England by the Holy See, via Laudabiliter. As the lord of Ireland was also the king of England, he was represented locally by a governor, variously known as justiciar, lieutenant, or lord deputy.

The Battle of Down, also known as the battle of Drumderg took place on or about 14 May 1260 near Downpatrick, in modern-day County Down, Northern Ireland. A Gaelic alliance led by Brian O'Neill and Hugh O'Connor were defeated by the Normans.

Bermingham is the Gaelicised version of 'de Birmingham' and is descended from the family of Warwickshire, England. The Irish version of the name MacFeorais/MacPheorais is derived from Pierce de Bermingham. The first recorded Bermingham in Ireland, Robert de Bermingham accompanied Richard de Clare or 'Strongbow' in Henry II's conquest of Ireland in 1172. On arrival he received: "an ancient monument, valued at 200 pounds, on which was represented in brass the landing of the first ancestor of the family of Birmingham in Ireland."

The House of Burke is the Irish branch of the Anglo-Norman noble family known as de Burgh. The surname Burke has been associated with Connaught for more than seven centuries.

Cambro-Normans were Normans who settled in southern Wales, and Welsh Marches, after the Norman invasion of Wales, allied with their counterpart families who settled England following its conquest.

From the 12th century onwards, a group of Normans invaded and settled in Gaelic Ireland. These settlers later became known as Norman Irish or Hiberno-Normans. They originated mainly among Cambro-Norman families in Wales and Anglo-Normans from England, who were loyal to the Kingdom of England, and the English state supported their claims to territory in the various realms then comprising Ireland. During the High Middle Ages and Late Middle Ages the Hiberno-Normans constituted a feudal aristocracy and merchant oligarchy, known as the Lordship of Ireland. In Ireland, the Normans were also closely associated with the Gregorian Reform of the Catholic Church in Ireland. Over time the descendants of the 12th-century Norman settlers spread throughout Ireland and around the world, as part of the Irish diaspora; they ceased, in most cases, to identify as Norman, Cambro-Norman or Anglo-Norman.

John's First Expedition to Ireland refers to a visit to the Island of Ireland by John Plantagenet as part of a campaign to secure the influence of the House of Plantaganet and the Crown of England, who planned to set up a Kingdom of Ireland within the Angevin Empire. John was himself a future King of England, the son of Henry II of England and had been declared Lord of Ireland by his father at the Council of Oxford in 1177. Despite his own ambitions for the Kingdom of Jerusalem, John Lackland was sent west to Ireland by his father and landed at Waterford in April 1185.

Mac William Íochtar, also known as the Mayo Burkes, were a fully Gaelicised branch of the Hiberno-Norman House of Burke in Ireland. The territory covered much of the northern part of the province of Connacht. The Mac William Íochtar functioned as a regional king and received the White Rod. The title was a successor office to the Lord of Connacht which ended upon the assassination of William Donn de Burgh, 3rd Earl of Ulster, in June 1333.

The Pale or the English Pale was the part of Ireland directly under the control of the English government in the Late Middle Ages. It had been reduced by the late 15th century to an area along the east coast stretching from Dalkey, south of Dublin, to the garrison town of Dundalk. The inland boundary went to Naas and Leixlip around the Earldom of Kildare, towards Trim and north towards Kells. In this district, many townlands have English or French names, the latter associated with Norman influence in England.

de Vesci is the surname of an old Norman noble family originating from Vassy, Calvados, also known as the House of de Vesci. The first records are about Robert de Vesci, Norman conqueror and Ivo de Vesci, Lord of Alnwick. The de Vesci family held lands in England and Ireland. The family was also linked to the Scottish Crown through the marriage of Eustace de Vesci to Margaret, the oldest but illegitimate child and daughter of William the Lion by a daughter of Adam de Hythus. William de Vesci was one of the competitors for the Crown of Scotland, upon the death of Margaret, Maid of Norway in 1290.
