The Celtic nations are territories in North-West Europe in which that area's own Celtic languages and cultural traits have survived. The term "nation" is used in this context to mean a generally defined region that is associated with a common identity, language or culture. It is not synonymous with "sovereign state", but rather with traditional territories.
The six territories recognised as Celtic nations are Brittany (Breizh), Cornwall (Kernow), Ireland (Éire), the Isle of Man (Mannin), Scotland (Alba), and Wales (Cymru). In addition, areas of the northern Iberian Peninsula, particularly Galicia, are sometimes identified as part of the Celtic nations, due to the unique culture of the region. Unlike the others, however, no Celtic language was spoken there in modern times. Before the expansions of the Roman Republic and Germanic tribes, a significant part of Western Europe was mainly Celtic.
