who are the celts and where did they come from
Celts The Celts (/ˈkɛlts/ or /ˈsɛlts/, see pronunciation of Celt for different usages) were an Indo-European people in Iron Age and Medieval Europe who spoke Celtic languages and had cultural similarities,[1] although the relationship between ethnic, linguistic and cultural factors in the Celtic world remains uncertain and controversial.[2] The exact geographic spread of the ancient Celts is also disputed; in particular, the ways in which the Iron Age inhabitants of Great Britain and Ireland should be regarded as Celts has become a subject of controversy.[1][2][3][4]
