The Welsh word Cymru, along with Cymry, was falsely supposed by 17th-century celticists to be connected to the Biblical Gomer, or to the Cimbri or the Cimmerians of Antiquity. In reality it is descended from the Brittonic word combrogi, meaning "fellow-countrymen". The term thus conveys something like " fellow-countrymen". The use of Cymry as a self-designation seems to have arisen in the post-Roman Era, to refer collectively to the Brythonic peoples of Britain, inhabiting what are now Wales, Cornwall, Northern England, and Southern Scotland. It came into use as a self-description probably before the 7th century and is attested in a praise poem to Cadwallon ap Cadfan . In Welsh literature, the wordCymry was used throughout the Middle Ages to describe the Welsh, though the older, more generic term Brythoniaid continued to be used to describe any of the Britonnic peoples and was the more common literary term until c. 1100. Thereafter Cymry prevailed as a reference to the Welsh. Until c. 1560 the word was spelt Kymry or Cymry, regardless of whether it referred to the people or the country. The Latinised form Cambria was coined in the Middle Ages, and was used regularly by Geoffrey of Monmouth.
Cambria in legend
According to Geoffrey of Monmouth in the first part of his pseudohistoryHistoria Regum Britanniae, the TrojanBrutus had three sons, among whom he divided his lands after landing in Britain and subduing Gogmagog. His eldest son, Locrinus, received the land between the riversHumber and Severn, which he called Loegria. His second son, Albanactus, got the lands beyond the Humber, which took from him the name of Albany. The youngest son, Camber, was bequeathed everything beyond the Severn, which was called after him "Cambria". This legend was widely prevalent throughout the 12th–16th centuries.
Legacy
The name “Cambria” lives on in some local names, e.g. Cambrian Line, Cambrian Way. It is also used internationally in geology to denote the geologic period between around 542 million years and 488.3 million years ago; in 1835 the geologist Adam Sedgwick named this geological period the Cambrian, after studying rocks of that age in Wales. It is also a rare female name. It is also found in the name of a number of colleges stretching across North East Wales – Coleg Cambria. It is also referenced in the well-known song “Men of Harlech“, which regales an event of exceptional endurance and valor in 15th century Wales. This song is popular with supporters of Cardiff City Football Club, and also the Welsh National Team. Once the name used for most of upland Wales, the term Cambrian Mountains is now more localised and includes the area from Pumlumon down to Mynydd Mallaen. Cambria is the name of a font in Microsoft Windows.
