IN: The Bretons (Breton: Bretoned, Breton pronunciation: [bre'tonet]) are an ethnic group located in the region of Brittany in France. They trace much of their heritage to groups of Brittonic speakers who immigrated from southwestern Great Britain, particularly Cornwall and Devon, to expand their territory onto the continent. They also descend in some parts from Vikings. They migrated in waves from the 3rd to 9th century (most heavily from 450-600) into Armorica, which was subsequently named Brittany after them.

The Breton language is a very important part of Breton identity. Breton itself is one of the Brittonic languages and is closely related to Cornish and more distantly to Welsh. Breton is thus an Insular Celtic language and is more distantly related to the long-extinct Continental Celtic languages such as Gaulish that were formerly spoken on the European mainland, including the areas colonised by the ancestors of the Bretons.  In eastern Brittany, a regional langue d'oil, Gallo, developed; it shares certain areal features such as points of vocabulary, idiom, and pronunciation with Breton but is a Romance language). Neither language has official status under French law; however, some still use Breton as an everyday language (particularly the older generation) and bilingual road signs are common in the west of Brittany.  From 1880 to the mid-20th century, Breton was banned from the French school system and children were punished for speaking it in a similar way to the application of the Welsh Not in Wales during the 19th and 20th centuries. The situation changed in 1951 with the Deixonne Law allowing Breton language and culture to be taught 1-3 hours a week in the public school system on the proviso that a teacher was both able and prepared to do so. In modern times, a number of schools and colleges have emerged with the aim of providing Breton-medium education or bilingual Breton/French education.  There are four main Breton dialects: Gwenedeg (Vannes), Kerneveg (Cornouaille), Leoneg (Leon) and Tregerieg (Tregor), which have varying degrees of mutual intelligibility. In 1908, a standard orthography was devised. The fourth dialect, Gwenedeg, was not included in this reform, but was included in the later orthographic reform of 1941.

Is it taught in schools?

input: In the following months, Jericho became a major force in The Invasion storyline in which WCW and ECW joined forces to overtake the WWF. Jericho remained on the side of the WWF despite previously competing in WCW and ECW. However, Jericho began slow turning into a villain by showing jealousy toward fellow WWF member The Rock. They faced each other in a match at No Mercy for the WCW Championship after Jericho defeated Rob Van Dam in a number one contenders match. Jericho won the WCW Championship when he pinned The Rock after debuting a new finisher, the Breakdown, onto a steel chair, winning his first world title in the process. One night later, the two put their differences aside and won the WWF Tag Team title from the Dudley Boyz.  After they lost the title to Test and Booker T, they continued their feud. On the November 5 episode of Raw, The Rock defeated Jericho to regain the WCW Championship. Following the match, Jericho attacked The Rock with a steel chair. At Survivor Series, Jericho solidified his heel turn by almost costing The Rock, and the WWF, victory in their elimination matchup by attacking The Rock again. At Vengeance, Jericho defeated both The Rock for the WCW Championship (unbranded and only referred to as the World Championship following Survivor Series) and Stone Cold Steve Austin for his first WWF Championship on the same night to become the first wrestler to hold both championships at the same time, which made him the first-ever Undisputed WWF Champion, as well as the fourth Grand Slam winner under the original format. He retained the title at Royal Rumble against The Rock and at No Way Out against Austin. Jericho later lost the title to Triple H in the main event of WrestleMania X8.  After his title loss, Jericho became a member of the SmackDown! roster and continued his feud with Triple H. The rivalry culminated at Judgment Day when Triple H defeated Jericho in a Hell in a Cell match.
