Tadhg Ó Cellaigh, also known as Tadhg mac Domnall O Cellaigh (Anglicized: Teig O'Kelly) (died 10 August 1316) was King of

Uí Maine and Chief of the Name
.

Background

Tadhg was one of five sons of Domhnall mac Conchobar mac Tadhg Taillten Ó Cellaigh, listed as

"Gilbert, King of Hy-Many, David, Tadhg Mor of the Battle of Ath na Righ, and Conchobhar, King of Hy-Many, and Aedh. Only two of them were by the same mother, viz., Tadhg and Conchobhar, and their mother was Abis, the daughter of O'Flainn O'Flynn."

King of Ui Maine

Tadhg usurped his brother, Gilbert Ó Cellaigh in the wake of the war of 1315–16, which arose with the return of Ruaidhri mac Cathal Ó Conchobair from Ulster and his successful seizure of the kingship of Connacht from his cousin, Fedlim Ó Conchobair. Tadhg expelled Gilbert and allied with Ruaidhri, who

assembled the men of Connacht and Brefne, together with many gallowglasses, and penetrated to the midst of

Roscommon, Randoon and Athlone
, as well as all the houses which lay on his route ... he took pledges and hostages of the rest of the Sil Murray and was made king on Carnfree. After this he remained for some time among them, ravaging every neighbour who was not submissive to him.

Winter campaign

Tadhg accompanied Ruaidhri on his subsequent winter raids around Connacht, such as those at

Leith Luigne and the slopes of Sliab Gam, and in particular to Glenn Fathraim, where they killed many thousand cows and sheep and horses. At that time they stripped women and ruined children and lowly folk, and never within the memory of man were so many cattle, fruitlessly destroyed in one place.

Returning to Ui Maine, he proceeded to burn the castle of

Máenmaige
.

As a result, both of the warfare and severe climatic conditions, "Many afflictions in all parts of Ireland: very many deaths, famine and many strange diseases, murders, and intolerable storms as well."

Moin Crinnoge

In February the two Ó Conchobairs fought each other at Tochar Mona Conneda (now Moin Crinnoge). Rudhri was defeated, and Fedlim "plundered the officers of Ruaidri O Conchobair and seized the kingship of Connacht from Assaroe (

Anglo-Irish
of Connacht.

Athenry

Fedlim's army, numbering as many as two thousand plus, seem to have assembled at Ballinasloe in late July or early August upon receiving the news that Sir William Liath de Burgh had returned from Scotland with Gallowglass mercenaries, and was assembling an army at Athenry to fight Fedlim.

Tadhg led the army of

Uí Maine and Síol Anmchadha, along with their vassals
, arriving at Athenry by 10 August 1316

The Second Battle of Athenry was fought on that day, and Fedlim's army soundly defeated, with "Tadc O Cellaig, king of Ui Maine [falling] with him, together with twenty-eight men who were entitled to succeed to the kingship of Ui Maine." Fedlim and his household bodyguard were slaughtered at what is now known as Kingsland, a plateau due east of, and overlooking, the town.

Final hours

Tadhg, however, survived the battle, and with a single bodyguard, hid in the woods outside Athenry. In the evening, John Husse, the town executioner and his servant were among the many local men surveying the battlefield for survivors and loot. Tadhg stepped out of the woods and made a pledge to Husse that, if he would switch sides and be his man, Tadhg would guarantee him power and position. Husse's servant agreed with Tadhg and urged his master to acquiesce.

In reply, Husse unsheathed his sword and beheaded his servant on the spot. He then engaged Tadhg's servant, defeated him, and fought Tadhg in a one-on-one sword fight. He ran Tadhg through and beheaded him and his bodyguard. Husse returned to Athenry, receiving reward from his lord, Rickard de Bermingham, for the three heads. Tadhg's head, along with that of King Fedlim, was surmounted on the twin towers of the main gate of Athenry, as the most dangerous of the defeated Irish. Their heads are featured to this day in the coat of arms of Athenry.
