Brian Bóruma mac Cennétig, (c. 941–23 April 1014), (English: Brian Boru, Middle Irish: Brian Bóruma, Irish: Brian Bóroimhe), was an Irish king who ended the domination of the High Kingship of Ireland by the Uí Néill. Building on the achievements of his father, Cennétig mac Lorcain, and especially his elder brother, Mathgamain, Brian first made himself King of Munster, then subjugated Leinster, making himself ruler of the south of Ireland. He is the founder of the O'Brien dynasty.

The Uí Néill king Máel Sechnaill mac Domnaill, abandoned by his northern kinsmen of the Cenél nEógain and Cenél Conaill, acknowledged Brian as High King at Athlone in 1002. In the decade that followed, Brian campaigned against the northern Uí Néill, who refused to accept his claims, against Leinster, where resistance was frequent, and against the Norse Gaelic Kingdom of Dublin. Brian's hard-won authority was seriously challenged in 1013 when his ally Máel Sechnaill was attacked by the Cenél nEógain king Flaithbertach Ua Néill, with the Ulstermen as his allies. This was followed by further attacks on Máel Sechnaill by the Dubliners under their king Sihtric Silkbeard and the Leinstermen led by Máel Mórda mac Murchada. Brian campaigned against these enemies in 1013. In 1014, Brian's armies confronted the armies of Leinster and Dublin at Clontarf near Dublin on Good Friday. The resulting Battle of Clontarf was a bloody affair, with Brian, his son Murchad, and Máel Mórda among those killed. The list of the noble dead in the Annals of Ulster includes Irish kings, Norse Gaels, Scotsmen, and Scandinavians. The immediate beneficiary of the slaughter was Máel Sechnaill who resumed his interrupted reign.

Alan Stivell (born Alan Cochevelou January 6, 1944) is a Breton musician and singer, recording artist and master of the celtic harp who from the early 1970s revived global interest in the Celtic (specifically Breton) harp and Celtic music as part of world music.

Alan was born in the Auvergnat town of Riom. His father Georges (Jord in Breton) Cochevelou was a civil servant in the French Ministry of Finance who achieved his dream of recreating a Celtic or Breton harp in the small town of Gourin, Brittany. In 1953, Alan began playing the instrument at the age of nine under the tutelage of his father and Denise Megevand, a concert harpist. Alan also learned Celtic mythology, art and history as well as the Breton language, traditional Breton dance and the Scottish bagpipe and the bombarde, a traditional Breton instrument, from the oboe family. Alan began playing concerts at eleven years and studying traditional Breton, English, Irish, Scottish, and Welsh folk music, also learning the drum, Irish flute, and tin whistle. He competed in and won several Breton traditional music competitions in the Bleimor Pipe band. Alan spent his childhood in Paris, with its cosmopolitan influences from France, Algeria, Morocco and elsewhere. But he fell in love with Breton music and Celtic culture in general, and often went back in his teens to Brittany.

Nolwenn Leroy, (born 28 September 1982 in Saint-Renan, Finistère, Brittany), is a French singer and songwriter, discovered by the French television reality show Star Academy. She is best known for her two Number One singles "Cassé" and "Nolwenn Ohwo!".

Leroy's parents left Saint-Renan, with her, when she was four years old. After living in Paris, Lille, and Guingamp, her mother Murielle Leroy and her younger sister settled with Leroy's grandparents in Saint-Yorre. Her mother had been divorced from her father, professional footballer Jean-Luc Le Magueresse, in 1993.

She studied at the "Collège des Célestins" in Vichy. When Leroy was eleven, her music teacher noticed her musical talents and encouraged her to learn the violin. At the age of thirteen she won "Les écoles du désert", a contest sponsored by the Cora supermarket chain, consequently travelling with a humanitarian mission from Gao to Timbuktu, Mali; she later claimed this had a profound influence on her.

In July 1998, she was awarded a scholarship by the Vichy Rotary Club to travel to Cincinnati, Ohio, as an exchange student. While there, she also attended the Performing Arts School. Returning to France, and speaking fluent English, she began classical singing classes at the Vichy music conservatory. From 2001 she studied law at the University of Clermont-Ferrand, for a potential alternative career to music.
