The House of Burgh (; ; ), also known by the family names of Burke and Bourke (), is an Irish family, descending from the Anglo-Norman de Burgh dynasty, who played a prominent role in the Anglo-Norman invasion of Ireland, where they settled and attained the earldoms of Kent, Ulster, Clanricarde, and Mayo at various times, and they have provided queens consort of Scotland and Thomond and Kings of England via a matrilineal line. The original (Ulster) line became extinct in 1363, along with the Clanricarde line in 1916, though the Mayo line is represented by the current Earl of Mayo. His direct descendants still carry his surname (and its variants) today;
- Hubert de Burgh (c. 1170–before 1243), who served as Chief Justiciar and Regent of England, Justiciar of Ireland, and was created Earl of Kent. His descendants changed their name to 'Burgh' after the Civil War in the seventeenth century;
- Thomas de Burgh, who became Castellan of Norwich; and
- Geoffrey de Burgh (c. 1180–1228), who became Bishop of Ely.
Descendants of Hubert de Burgh, Earl of Kent
Hubert de Burgh
The grant of the Earldom of Kent to Hubert de Burgh was limited to himself and any male heirs born to his final wife, Princess Margaret of Scotland, but their only child was a daughter who was herself childless. Though the earldom of Kent became extinct on Hubert's death, his sons from a previous marriage, John and Hubert, inherited his lands and their descendants passed into relative obscurity until 1487, when Thomas Burgh (c.1431–1496) of Gainsborough, Lincolnshire (thought to be descended from Hubert, Earl of Kent's younger son Hubert) was summoned to Parliament as Baron Burgh (or Borough) of Gainsborough, though he never took his seat and the creation of this barony is therefore disputed.
Barons Burgh (1529–1602)
Thomas Burgh's son, Sir Edward Burgh (c.1463–1528), did not sit in Parliament. However, his son, Thomas Burgh (c.1488–1550), was summoned to Parliament in 1529 and this was deemed as the creation of the barony. In this barony, Thomas, 3rd Baron Burgh was Lord Deputy of Ireland (1597), and his younger brother, Sir John Burgh (d. 1594), was a distinguished soldier and sailor. Robert, 6th Baron Burgh died as a young child in 1602, and the barony fell into abeyance among his four sisters.
Earls of Ulster (1264–1363)

Richard Mór's second son, Walter de Burgh (c.1210–71), continued warfare against the native chieftains and added greatly to his vast domains by obtaining, from Prince Edward, a grant of "the county of Ulster" (c. 1255) in consequence of which he was styled later Earl of Ulster.
Walter, 1st Earl of Ulster was succeeded by his son, Richard Óg de Burgh, 2nd Earl of Ulster. In 1286, he ravaged and subdued Connacht, and deposed the chief native king, (Brian O'Neill), substituting his own nominee. He also attacked the native king of Connacht, in favour of the branch of O'Conors that his family supported. He led his forces from Ireland to support Edward I in his Scottish campaigns, and on Edward Bruce's invasion of Ulster (1315), Richard marched against him, despite having given his daughter, Elizabeth, in marriage (c. 1304) to King Robert I of Scotland, Edward's older brother. Occasionally summoned to English parliaments, Richard spent most of his forty years of activity in Ireland, where he was the greatest noble of his day, usually fighting the natives or his Anglo-Norman rivals to expand his family's land. The patent roll of 1290 shows that in addition to his lands in Ulster, Connacht and Munster, he held the Isle of Man, but later surrendered it to the king.
Richard, the 2nd Earl's grandson and successor was William Donn de Burgh, the Brown Earl (1312–33), son of John de Burgh (d. 1313) and Elizabeth, Lady of Clare (d. 1360), sister and co-heir of the last Clare Earl of Hertford (d. 1314). William Donn married Maud of Lancaster (daughter of Henry, 3rd Earl of Lancaster) and was appointed Lieutenant of Ireland (1331), but was murdered in his 21st year, leaving his only daughter, Elizabeth de Burgh, as the sole heiress not only of the de Burgh possessions but of the vast Clare estates.
Elizabeth was married in childhood to Lionel, 1st Duke of Clarence (third son of Edward III) who was recognized in her right as Earl of Ulster. It is from them that the Yorkist Plantagenets later derived their claim to the throne of England.
Their descendant, Edward, 4th Duke of York, ascended the throne in 1461 as King Edward IV of England, since then the Earldom of Ulster has been only held by members of the British royal family.
Elizabeth, Queen of Scots

Elizabeth de Burgh, daughter of Richard Óg de Burgh, 2nd Earl of Ulster, married Robert the Bruce in 1302 at the age of 13. The wedding most likely took place at Writtle, near Chelmsford, Essex and was arranged by either Richard or Edward I, King Edward having heavily encouraged it as a way to keep the loyalty of the Scottish nobility.
The family's two main branches were:
- Mac William Uachtar (Upper Mac William) or Clanricarde (in southern Connacht and Galway).
- Mac William Íochtar (Lower Mac William) in northern Connacht (Mayo).

The Gaelic title Mac William Uachtar (meaning "son of the upper William (de Burgh)") came to denote the head of the Burke family of Upper or south Connacht but the chief of this family was more popularly known by another Gaelic title, Clanricarde (meaning "(head of) Richard's family"). In 1543, the Mac William Uachtar (Upper Mac William) chief, Ulick na gCeann Burke (alias, MacWilliam) surrendered his lands in Connacht to Henry VIII, receiving these properties back to hold them, by English custom, as Earl of Clanricarde and Lord Dunkellin (1543). His son, Ulick Burke, received the Irish Marquessate of Clanricarde (first creation, 1646). His cousin and heir, Richard Burke, 6th Earl of Clanricarde was an uncle of Richard Burke, 8th Earl and John Burke, 9th Earl, both of whom fought for James II and paid the penalty for doing so (1691), but the latter was restored (1702), and his great-grandson, Henry de Burgh, 12th Earl, was created Marquess of Clanricarde (second creation, 1789). Henry left no son, but his brother, John de Burgh, 13th Earl was created Earl of Clanricarde (second creation, 1800) and the Marquessate was later revived (1825), for John's son, Ulick de Burgh, 14th and 2nd Earl. His heir, Hubert de Burgh-Canning was the 2nd and last Marquess. The Earldom of Clanricarde (second creation) passed by special remainder to the 6th Marquess of Sligo. This family, which changed its name from Burke to de Burgh (1752) and added that of Canning (1862), owned a vast estate in County Galway.

The Gaelic title Mac William Íochtar (meaning "son of the lower William (de Burgh)") came to denote the head of the Bourke family of lower or north Connacht. Seaán mac Oliver Bourke, 17th (Lord of) Mac William Íochtar was created Baron Ardenerie in 1580. Tibbot (Theobald) MacWalter Kittagh Bourke, 21st (Lord of) Mac William Íochtar, fled to Spain where he was created Marquess of Mayo (1602) in the Spanish peerage. Miles, 2nd Viscount (d. 1649) and Theobald, 3rd Viscount (d. 1652) suffered at Cromwell's hands, but Theobald, 4th Viscount was restored to his estates (some 50,000 acres) in 1666. The peerage became extinct or dormant on the death of John, 8th Viscount (1767).
In 1781, John Bourke, was created Viscount Mayo (1781) and later Earl of Mayo (1785). He was descended from the fourth son of Sir Thomas Bourke (d. 1397), whose second son, Edmund, was the ancestor of the Viscounts Mayo of the first creation. His younger brother was the politician Robert Bourke, 1st Baron Connemara who became Governor of Madras.
The baronies of Bourke of Castleconnell (1580) and Bourke of Brittas (1618), both forfeited in 1691, were bestowed on branches of the family which still has representatives in the baronetage and landed gentry of Ireland.

The original de Burgh coat of arms was adopted during the beginnings of the age of heraldry in the thirteenth century. It was blazoned as Or, a cross gules (a red cross on a gold shield). According to attributed legend, the arms originated during the Crusades while an ancestor of the de Burghs was fighting for King Richard the Lionheart. Given that this ancestor did not yet have a crest of his own, he carried a plain gold shield and it is said that, following a successful battle, the Lionheart marked a cross of blood on his shield stating "for your bravery, this shall be your crest". Origin stories such as this were attributed to noble and Royal families at the time with questionable historicity.
However, at a time when heraldry was only beginning to be established, these arms were identical with those of the Bigods, the ruling family of Norfolk. The Bigod arms had been adopted by Roger Bigod, 2nd Earl of Norfolk (d.1221) in the early thirteenth century but his great-grandson Roger Bigod, 5th Earl of Norfolk (d.1306) ceased using these arms after 1269. Glover's Roll, a sixteenth-century copy of a roll of arms of the 1250s, includes a depiction of the Or, a cross Gules of the Earl of Norfolk. The de Burgh claim to these arms may have been linked to the fact that Richard Óg de Burgh, 2nd Earl of Ulster was the son of Aveline FitzJohn (d.1274), daughter of Sir John FitzGeoffrey (d.1258) and his wife Isabel Bigod (c. 1212–1250), daughter of Hugh Bigod, 3rd Earl of Norfolk (c. 1182–1225).
Variations on this original shield were adopted by different branches of the family. For instance, the arms of the Burke/de Burgh family of Clanricarde added a black lion to the upper-left quadrant (Or, a cross gules in the first quarter a lion rampant sable).
