Celtic ethnic group

The Bretons are a Celtic ethnic group native to Brittany, north-western France. Originally, the demonym designated groups of Brittonic speakers who emigrated from southwestern Great Britain, particularly Cornwall and Devon, mostly during the Anglo-Saxon settlement of Britain. They migrated in waves from the 3rd to 9th century to the west of Armorica. That western part of Armorica was subsequently named after them, as were the inhabitants.

Breton Kingdoms in Depth

History

In the late fourth century, large numbers of British auxiliary troops in the Roman army may have been stationed in Armorica; Armorica corresponds with the current Brittany and most of Normandy. The ninth-century Historia Brittonum states that the emperor Magnus Maximus, who withdrew Roman forces from Britain, settled his troops in Armorica.

Nennius and Gildas mention a second wave of Britons settling in Armorica in the following century to escape the invading Anglo-Saxons and Scoti. Modern archaeology also supports a two-wave migration.

It is generally accepted that the Brittonic speakers who arrived gave the west of Armorica its current name as well as the Breton language, Brezhoneg, a sister language to Welsh and Cornish.

Culture

The Breton people are predominantly members of the Catholic Church, with minorities in the Reformed Church of France and non-religious people. Brittany was one of the most staunchly Catholic regions in all of France. Attendance at Sunday mass dropped during the 1970s and the 1980s; however, other religious practices, such as pilgrimages, have experienced a revival. This includes the Tro Breizh, which takes place in the shrines of the seven founding saints of Breton Christianity. The Christian tradition is widely respected by both believers and nonbelievers, who see it as a symbol of Breton heritage and culture.

A pardon is the patron saint's feast day of the parish. It often begins with a procession followed by mass in honour of the saint.
